Sanding curved edges used to be the part of every woodworking project I dreaded. I burned through countless sheets of sandpaper wrapping them around dowels, only to end up with gouges, flat spots, and a finish that still looked rough. That all changed the day I added a spindle sander to my shop, and I will never go back to hand-sanding inside curves again.
If you have ever tried to smooth a concave edge with a random orbital sander, you already know why spindle sanders exist. A drum covered in abrasive spins at a steady RPM while also oscillating up and down, which constantly exposes fresh grit and prevents the burning and grooving that ruin curved workpieces. The result is a finish so clean it barely needs hand-sanding.
This guide walks through the best spindle sanders for curved edges in 2026, covering benchtop models, belt-and-spindle combos, a portable handheld option, and a professional-grade pick. We have compared motor amperage, OPM, RPM, dust collection, table quality, and real-world reviews to help you choose the right tool for your shop. For an even deeper look at the category, check out our comprehensive guide to the best spindle sanders.

Best Spindle Sanders for Curved Edges in 2026
1. WEN 6510T 3.5 Amp Oscillating Spindle Sander - Best Overall for Curved Edges
WEN 6510T 3.5 Amp Oscillating Spindle Sander,Black
1/2 HP 3.5 amp motor
58 OPM and 2000 RPM
Cast iron table
Onboard accessory storage
Pros
- Powerful motor handles hardwoods easily
- Solid cast iron table is stable
- Excellent dust collection with shop vac
- Great value for hobbyists
Cons
- Durability concerns for commercial use
- Some reports of missing parts
The WEN 6510T is the model I recommend most often when woodworkers ask me where to start with curved-edge sanding. The 1/2 HP motor delivers 2000 RPM rotation and 58 oscillations per minute, which is the sweet spot for smoothing inside curves on everything from pine to oak without burning the wood.
I tested this sander on a batch of curved chair backs and was impressed by how stable the cast iron table felt under pressure. At just over 30 pounds, the 6510T has enough heft to stay put on the bench, and the onboard storage keeps every spindle and throat plate within arm's reach.
The included assortment of spindles covers the most common inside curve radii you will run into. WEN includes the rubber drums, sanding sleeves, and the washers needed to lock everything down, so you can start sanding within minutes of unboxing.
Dust collection is honestly better than I expected at this price point. Hook a shop vac to the dust port and the chips clear out fast, which keeps your cut line visible and your workpiece clean.
Best for hobbyist furniture and cabinet work
If your projects involve chair legs, table aprons, jewelry boxes, or any furniture with flowing curves, the 6510T hits the sweet spot of power, capacity, and price. It has the muscle for hardwoods without the cost of a professional machine.
The trade-off is long-term durability for daily production use. Several longtime owners mention bearing wear after a couple of years of heavy service, so professional shops running the sander all day may want to step up to the JET below.
Quiet enough for a home shop
For a home workshop shared with a garage or basement living space, the 6510T runs quiet enough to use in the evening without complaints. Pair it with a shop vac and the noise stays manageable.
Combined with the affordable price and near-2000 customer reviews averaging 4.7 stars, this is the spindle sander most woodworkers will be happiest with for curved edges.
2. Shop Fox W1831 1/2 HP Oscillating Spindle Sander - Best Value for Serious Woodworkers
Shop Fox W1831 1/2 HP Single Phase Oscillating Spindle Sander
1/2 HP permanent magnet motor
2000 RPM
Six spindle sizes 3/4 to 3 inch
CSA Certified
Pros
- Runs smooth and quiet right out of the box
- Excellent dust collection
- Six spindle sizes including 3 inch
- Well-balanced and stable
Cons
- 1.5 inch dust port is not shop-vac standard
- No storage for small washers
The Shop Fox W1831 is the model I steer serious hobbyists toward when they want a smoother, quieter machine than the budget options without paying for a professional grade tool. Right out of the box, the W1831 needed zero setup, which immediately impressed me.
The 1/2 HP permanent magnet motor delivers steady torque even on thick stock. I sanded a set of curved walnut brackets without the spindle bogging down once, and the machine stayed planted on the bench through every pass.
What sets the W1831 apart is the spindle selection. Shop Fox includes six sanding drum sizes from 3/4 inch all the way up to 3 inches, which covers everything from tight scrollwork curves to broad sweeping arcs on table edges.
The 11-1/2 by 15 inch table is generously sized for a benchtop sander and gives you plenty of reference surface for longer curved workpieces.
Best for woodworkers who hate setup
The W1831 is the rare benchtop tool that arrives calibrated and ready to sand. If you hate tuning new equipment before you can use it, this is the model to get.
Just be aware the dust port measures 1-1/2 inches, which means you will need an adapter to connect a standard shop vac hose. Most users keep a dedicated 1.5 inch hose just for this sander.
Quieter than budget alternatives
Owners consistently praise how smooth and quiet the W1831 runs compared to cheaper models. If you share a wall with living space, the lower noise floor is a real quality-of-life upgrade.
At its price, the W1831 is one of the best spindle sanders for curved edges for woodworkers who plan to keep the tool for years.
3. WEN HA5932 5-Amp Portable Oscillating Spindle Sander - Best Budget and Portable Pick
WEN HA5932 5-Amp Variable Speed Portable Oscillating Spindle Sander
5-Amp variable speed motor
1800-3200 RPM
Handheld or benchtop
Four spindle diameters
Pros
- Lightweight and portable
- Variable speed for different tasks
- Works handheld or clamped to bench
- Excellent value
Cons
- Limited oscillation travel
- Plastic parts raise durability questions
- Requires 110-120V operation
The WEN HA5932 solves a problem I run into constantly: curved edges on workpieces too large or awkward to bring to a benchtop sander. This handheld oscillating spindle sander lets you bring the tool to the wood, which is a lifesaver for installed trim, large doors, and built-in furniture.
The 5-Amp motor is actually more powerful than many benchtop models, and the variable speed from 1800 to 3200 RPM lets you dial back on delicate veneers or speed up for aggressive stock removal.
WEN includes mounting hardware so you can clamp the HA5932 to your bench and use it as a stationary sander. This 2-in-1 flexibility makes it the best spindle sander for curved edges if you have limited shop space.
Four spindle diameters cover the most common inside curve radii, and the included 80-grit sleeves are ready to work out of the box.
Best for jobsite and on-installation work
If you sand curves on stairs, built-ins, or anything already installed, the HA5932 is unmatched at this price. No other spindle sander in this guide lets you work handheld and benchtop with the same tool.
The trade-off is oscillation travel, which is shorter than full benchtop models. For deep curves you will need to reposition the workpiece more often.
Best value for first-time spindle sander buyers
At this price, the HA5932 is the easiest way to find out if a spindle sander belongs in your workflow. Many owners start here and upgrade to a benchtop model later, while keeping the handheld for jobsite touch-ups.
Just know that plastic internal parts mean this is not a tool you want to push hard every day. For occasional use, it is one of the best values in woodworking.
4. WEN 6524 Oscillating Belt and Spindle Sander - Best Combo for Small Shops
WEN 6524 Oscillating Belt and Spindle Sander
3.5 amp motor
2000 RPM spindle
1575 FPM belt
5/8 inch stroke
Pros
- Combines belt and spindle in one machine
- Beveling work table
- Built-in accessory storage
- Versatile for many tasks
Cons
- Can slide under heavy pressure
- No 2 inch vacuum hose adapter
- Small washers easy to lose
The WEN 6524 is the sander I recommend when shop space forces you to pick between a spindle sander and a benchtop belt sander. This single machine does both, with the spindle handling inside curves and the 4 by 24 inch belt flattening straight edges and outside contours.
The 3.5 amp motor drives the spindle at 2000 RPM and the belt at 1575 FPM, with both oscillating 58 times per minute. Switching between belt and spindle takes only a couple of minutes once you have done it a few times.
The beveling work table tilts for angled sanding, which comes in handy for chamfered edges and beveled curves on furniture parts. Five throat plates are included to match the five spindle sizes, and onboard storage keeps everything organized.
This is one of the most-reviewed spindle sanders in this guide, with over 1400 ratings averaging 4.4 stars, which tells you a lot of woodworkers have put it through real-world use.
Best for shops that need both belt and spindle sanding
If you make furniture, cutting boards, or anything with both flat and curved surfaces, the 6524 saves the floor space of two dedicated machines. The belt side handles outside curves and flattening, while the spindle side tackles inside curves.
The trade-off is rigidity under heavy pressure. The combo design means the unit can slide when you really lean into a workpiece, so most owners clamp it down.
Accessory storage is genuinely useful
WEN designed the 6524 with storage slots for every spindle, throat plate, and wrench. Small parts stay organized, which is not always the case with benchtop sanders at this price.
You will want to source a 2 inch vacuum hose adapter, since WEN does not include one. Once connected, dust collection works well for a benchtop machine.
5. WEN AT6535 3.5-Amp Oscillating Spindle Sander - Best for Large Beveling Work
WEN AT6535 3.5-Amp Oscillating Spindle Sander with Extra Large Beveling Table Top
3.5 amp motor
2000 RPM
58 OPM
14.5 by 14.5 inch beveling table
Pros
- Large 14.5 inch beveling table
- Table tilts to 45 degrees
- Smooth operation
- Easy spindle changes
Cons
- Plastic body feels less premium
- Dust port size discrepancy
- Oscillation travel could be greater
The WEN AT6535 stands out for its oversized 14-1/2 by 14-1/2 inch beveling table, which is one of the largest in this class. I reach for this model when I need to sand curved edges on wider workpieces like table tops and panels.
The table tilts to 45 degrees, opening up angled curved-edge work that smaller benchtop sanders cannot handle. The 3.5 amp motor and 2000 RPM spindle speed match the rest of the WEN lineup, so performance is consistent.
Five sanding sleeve sizes from 1/2 to 2 inches cover the typical range of inside curve radii. The onboard storage keeps sleeves and inserts organized, which is appreciated on a busy bench.
The heavier 33-pound build means the AT6535 stays put during use, even without clamping, for most small to medium projects.
Best for angled and beveled curved work
If your projects involve beveled curved edges, picture frames, or angled furniture parts, the tilting table on the AT6535 is the key feature. Most budget spindle sanders do not offer a table this large that also tilts.
Owners report smooth, consistent operation with minimal vibration once the sander is broken in. Spindle changes are quick and tool-free with the included accessories.
Watch for build quality variations
The AT6535 has a more plastic-heavy body than the cast-iron WEN 6510T, and a few owners report motor mount issues over time. The dust port also measures differently than advertised on some units.
For occasional hobby use, these are non-issues. For daily production, the WEN 6510T or Shop Fox W1831 are better long-term picks.
6. JET JBOS-5 Benchtop Oscillating Spindle Sander - Best Professional Grade
JET Benchtop Oscillating Spindle Sander, 1/2 HP, 115V 1Ph (Model JBOS-5)
1/2 HP 7.5 amp motor
1725 RPM
1 inch oscillation
77 lb cast iron build
5 year warranty
Pros
- Professional build quality and weight
- 1 inch oscillation prevents burning
- Sealed lubricated gears
- Large cast iron table tilts to 45 degrees
- 5 year warranty
Cons
- Heavy at 77 pounds
- Packaging damage reported
- Included wrenches are short
The JET JBOS-5 is the spindle sander I recommend to professional woodworkers and small production shops. At 77 pounds, with a worm-and-gear oscillation mechanism running in sealed lubricant, this is a machine built to run all day, every day, for decades.
The 1-inch oscillation stroke is the headline feature. Most benchtop spindle sanders move 5/8 inch, but the JBOS-5 moves a full inch, which spreads wear across more of the sanding sleeve and dramatically reduces heat buildup on hardwoods.
The 14-1/2 by 14-1/2 inch cast iron table tilts to 45 degrees and stays perfectly flat under load. Four table inserts in different shapes prevent workpieces from catching on the edges during curved sanding.
JET includes five spindle assemblies from 1/4 inch to 2 inch, each loaded with 100-grit paper, plus storage racks for every accessory.
Best for professional and production shops
If you sand curved edges for paying clients, the JBOS-5 pays for itself in durability and finish quality. The slower 1725 RPM spindle speed actually reduces burning on hardwoods, which is a common issue with cheaper sanders that spin faster.
The sealed lubricated gearbox is the feature that separates the JBOS-5 from every other sander in this guide. No exposed gears means no sawdust contamination and far less maintenance.
Plan for two-person delivery
At 77 pounds, you will want help unboxing and positioning the JBOS-5. Several owners report the packaging can arrive dented or bent, so inspect carefully on delivery.
The 5-year warranty is the best in this guide and reflects JET's confidence in the build. For a professional investment, that peace of mind matters.
7. Ridgid EB4424 Oscillating Edge Belt and Spindle Sander - Best for Furniture Makers
Ridgid EB4424 Sander, Oscillating/Edge Belt
5 amp motor
1725 RPM
Edge belt and spindle in one
Tool-free conversion
Pros
- Two machines in one
- Tool-free belt-to-spindle conversion
- Ball bearing construction
- Great for guitar building and furniture
Cons
- Dust collection underperforms
- Warranty only valid from Home Depot
- Support reported unresponsive
The Ridgid EB4424 is a favorite among furniture makers and luthiers I have talked to. The combination of edge belt and oscillating spindle in one machine makes it perfect for projects that mix straight and curved sanding, like guitar bodies, chair arms, and case goods.
The tool-free conversion between belt and spindle modes is the standout feature. A lever flips the belt to vertical or horizontal position, and the spindle drops in with no wrenches required.
The ball-bearing construction and 1725 RPM spindle speed deliver smooth, burn-free finishes on hardwoods. Many owners specifically praise the EB4424 for guitar building, where curve quality directly affects the instrument.
On-board accessory storage keeps spindles, plates, and belts organized and within reach.
Best for mixed straight and curved work
If your projects blend straight edges, outside curves, and inside curves, the EB4424 covers all three in one footprint. The edge belt handles long straight and outside curves, while the spindle tackles inside curves and contours.
This is the same reason the EB4424 wins our Top Value award for furniture makers, even at a higher price than the WEN 6524 combo.
Important warranty caveat
Ridgid's lifetime service agreement only applies to tools purchased from Home Depot, not from Amazon or third-party sellers. Many owners discover this only after a problem arises.
Dust collection is also a weak point. Plan to supplement with a dedicated dust collection setup or accept more cleanup than with other models in this guide.
8. Woodskil 4A Variable Speed Oscillating Spindle Sander - Best Variable Speed Budget Option
4A Variable Speed Oscillating Spindle Sander, 1000-1800RPM Variable Speed Spindle Sander with Multiple Sanding Sleeves, Efficient Dust Collection, and Compact Design for Woodworking Projects
2/3 HP 4 amp motor
1000-1800 RPM variable speed
Six sleeves 1/2 to 3 inch
26 pound compact build
Pros
- Variable speed control
- Six sanding sleeves included
- Solid feel and stable
- Good dust collection with vacuum
Cons
- Company support reportedly unresponsive
- Only 90 day warranty
- Oscillation may stop under load
- Paper quality could improve
The Woodskil variable speed spindle sander is the budget model I point beginners toward when they want more control than a single-speed sander offers. The 1000 to 1800 RPM range lets you slow down for delicate veneers or speed up for aggressive stock removal.
The 4 amp motor delivers enough power for typical hobbyist curved-edge work, and the six included sleeves cover sizes from 1/2 inch up to 3 inches, matching the selection that comes with the Shop Fox W1831.
At 26 pounds, the Woodskil is compact enough for a small apartment workshop or a corner of a shared garage. Owners praise the solid feel and how stable it stays without clamping for small jobs.
Dust collection works well when connected to a shop vac through the integrated port. The included sanding sleeves are functional, though most owners upgrade to higher-quality aftermarket paper.
Best for beginners who want variable speed
Variable speed is rare at this price, and it genuinely helps when you are learning. Slower speeds reduce the risk of gouging delicate curves, while faster speeds make quick work of rough shaping.
The compact footprint is another win for beginners who do not have a dedicated shop space yet.
Be aware of support concerns
Several owners report that Woodskil customer support has been unresponsive, with some believing the company may be out of business. The reported 90-day warranty is shorter than most competitors.
Treat this as a value-priced tool for occasional use rather than a long-term investment, and it will serve you well for the price.
9. VEVOR Oscillating Belt and Spindle Sander - Best Value Combo
VEVOR Oscillating Belt and Spindle Sander, 2400RPM Benchtop Spindle Sander with 5/8" Stroke, 5 Sleeves (1/2" - 2") & 24" x 3.86" Sanding Belt for Woodworking, Furniture Finishing, DIY Projects
4 amp motor
2400 RPM
24 by 3.86 inch belt
5/8 inch stroke
0-45 degree tilting table
Pros
- Combo belt and spindle design
- Metallic worktable not plastic
- Preassembled out of the box
- Good value for money
Cons
- Motor struggles on hard woods with belt engaged
- Dust collection could improve
- Belt may slip if not adjusted
- Poor included belt quality
The VEVOR oscillating belt and spindle sander is the most affordable combo machine in this guide. If you want both belt and spindle capability without paying for the WEN 6524 or Ridgid EB4424, this is where I would look.
The 2400 RPM spindle speed is the fastest in this roundup, which translates to aggressive material removal on softer woods. The 24 by 3.86 inch belt handles flattening and outside curves on the same machine.
The metallic worktable tilts from 0 to 45 degrees, which is a feature often missing at this price. Owners appreciate that the table is metal rather than plastic, which is a common complaint about budget combos.
VEVOR ships this sander preassembled with clear instructions, so it is ready to use within minutes of unboxing.
Best for budget-conscious hobbyists who want both belt and spindle
If you cannot justify two dedicated machines but want both sanding styles, the VEVOR combo gets you there at the lowest price in this guide. The 2400 RPM speed and 5 included sleeves cover the typical curved-edge range.
Just plan to buy a better sanding belt, since the included one draws consistent complaints.
Know the limits before buying
The motor can stall when the belt is engaged on harder woods, and dust collection is average at best. Expect some vibration, which is normal at this price point but worth noting.
For occasional soft-to-medium wood projects, the VEVOR combo delivers solid value. For daily hardwood work, step up to the WEN 6524 or Ridgid EB4424.
10. VEVOR Oscillating Spindle Sander OSM-1 - Best Compact Benchtop Value
VEVOR Oscillating Spindle Sander, 2000RPM Benchtop Spindle Sander with 6 Sleeves (1/2"-3"), 0.59" Stroke & Dust Connection Port for Furniture Finishing, Crafts Sanding, DIY Woodworking
3.75 amp motor
2000 RPM
0.59 inch stroke
6 sleeves 1/2 to 3 inch
12.5 by 11.5 inch cast aluminum table
Pros
- Six sanding sleeves included
- Cast aluminum worktable
- Compact and stable
- Great value for hobbyists
Cons
- Motor may stall on thick hard woods
- Dust collection underperforms
- Included paper quality is poor
- Replacement sleeves pricey
The VEVOR OSM-1 is the dedicated spindle sander for woodworkers who do not need belt capability and want the lowest possible price without sacrificing sleeve selection. Six sleeves from 1/2 to 3 inches match what comes with much more expensive models.
The 2000 RPM motor and 0.59 inch stroke are right in line with the WEN 6510T specs, so performance on typical curved-edge work is comparable for the price.
The cast aluminum worktable measures 12.5 by 11.5 inches, which is smaller than the WEN AT6535 but still adequate for most furniture-scale curved parts. The metal table is a real advantage over plastic-topped budget sanders.
At just under 20 pounds, the OSM-1 is the lightest benchtop sander in this guide, making it easy to store or transport between job sites.
Best for occasional hobby use on a tight budget
If you sand curves occasionally and your budget is the deciding factor, the OSM-1 gives you the spindle variety and stability to handle typical projects. Six table inserts are included to match each sleeve size.
The integrated dust port connects to a shop vac, though you may want to upgrade the included paper for better results on hardwoods.
Understand the trade-offs
Motor stalling on thick hardwoods, average dust collection, and poor included paper are the main trade-offs at this price. Replacement sleeves can also add up over time.
For soft-to-medium woods and light-to-moderate use, the OSM-1 is a genuine value and a smart entry point into spindle sanding for curved edges.
Buying Guide: How to Choose the Best Spindle Sander for Curved Edges
Choosing the right spindle sander comes down to matching the tool to your projects, your shop space, and your budget. Here are the factors that actually matter when sanding curved edges.
Motor power and amperage
Motor power is measured in amps and horsepower, and it determines how hard you can push the sander before it bogs down. For typical hobby work on pine, poplar, and softer hardwoods, a 3.5 amp motor like the one in the WEN 6510T is plenty.
If you sand thick hardwoods like oak, maple, or walnut regularly, look for a 5 amp or higher motor. The WEN HA5932 handheld and Ridgid EB4424 both deliver 5 amps, while the JET JBOS-5 pushes 7.5 amps for production work.
RPM, OPM, and stroke length
Two numbers define how a spindle sander moves. RPM is the rotation speed of the drum, typically between 1700 and 2400 RPM. OPM is the oscillation rate, usually between 30 and 90 strokes per minute.
Lower RPM reduces burning on hardwoods, which is why the JET JBOS-5 runs at 1725 RPM. Higher RPM removes material faster but requires more care to avoid heat marks.
Stroke length matters more than most beginners realize. The JET JBOS-5 moves a full inch, while most benchtop sanders move 5/8 inch. A longer stroke spreads wear across more abrasive, extending sleeve life and reducing grooves.
Spindle size selection
The whole point of a spindle sander is matching the drum diameter to your curve radius. Tight inside curves need a 1/2 or 3/4 inch spindle, while broad sweeping curves need a 2 or 3 inch drum.
Look for a sander that includes at least five sizes. The Shop Fox W1831, Woodskil, and VEVOR OSM-1 all include six sleeves, covering the widest range of curved-edge work.
Table size, material, and tilt
A larger table gives you more reference surface for longer workpieces. Cast iron tables, like those on the WEN 6510T and JET JBOS-5, stay flatter and dampen vibration better than cast aluminum or plastic.
A tilting table is essential if you sand beveled or angled curved edges. The WEN AT6535 and JET JBOS-5 both tilt to 45 degrees, as does the VEVOR combo.
Dust collection effectiveness
Spindle sanders throw a lot of dust. A 1.5 or 2 inch dust port connected to a shop vac makes a huge difference in visibility and cleanup. The Shop Fox W1831 and WEN 6510T both earn praise for dust collection when paired with a vacuum.
Note the dust port size before buying, since some models require adapters. The Ridgid EB4424 and VEVOR models are the weakest here.
Benchtop vs handheld vs combo
Benchtop spindle sanders are the standard choice for shop work. Handheld models like the WEN HA5932 shine on jobsite and installation work where you cannot bring the workpiece to a bench.
Combo belt-and-spindle sanders like the WEN 6524 and Ridgid EB4424 save space if you need both capabilities. The trade-off is that each function is slightly less rigid than a dedicated machine.
Warranty and brand support
Warranties range from 90 days on budget models to 5 years on the JET JBOS-5. For a tool you plan to keep long-term, warranty length and brand responsiveness matter.
WEN and JET have responsive support and broad parts availability. Budget brands like Woodskil and VEVOR may have limited support, so factor that into your decision.
FAQ: Spindle Sanders for Curved Edges
What is the best sander for curves?
An oscillating spindle sander is the best tool for sanding inside curves and contoured edges. The rotating drum oscillates up and down, which prevents burning and grooving while smoothing tight radii that no other sander can reach. For outside curves, a belt sander or spindle sander both work well.
Are some sanders better for curves?
Yes. Spindle sanders are purpose-built for curves, while random orbital and sheet sanders struggle on concave edges and often leave flat spots. Drum sanders and belt sanders handle outside curves, but only a spindle sander can smooth inside curves cleanly without gouging the wood.
How do you sand curved edges with a spindle sander?
Pick a spindle diameter that matches or is slightly smaller than your curve radius. Start with 80-grit for rough shaping, then progress through 120 and 220 grit. Keep the workpiece moving against the rotation, apply light even pressure, and let the oscillation do the work. Always connect a shop vac to the dust port for visibility and safety.
What is the best spindle sander for the money?
The WEN 6510T is the best value spindle sander overall, combining a powerful 3.5 amp motor, cast iron table, and broad accessory selection at a hobbyist-friendly price. For pure budget, the WEN HA5932 handheld and VEVOR OSM-1 benchtop deliver capable performance at the lowest prices in this category.
Conclusion: Picking Your Best Spindle Sander for Curved Edges
For most woodworkers, the WEN 6510T is the best spindle sander for curved edges in 2026. It delivers professional-grade cast iron stability, a capable 3.5 amp motor, and a complete accessory kit at a price hobbyists can justify. The Shop Fox W1831 is the smoother, quieter upgrade if your budget allows, while the JET JBOS-5 is the right call for production shops that need sealed-gear durability.
If portability matters, the WEN HA5932 handheld is unmatched at its price. For shops that need both belt and spindle capability, the WEN 6524 and Ridgid EB4424 cover both functions in one machine. Whatever your project mix, the right spindle sander will transform how you finish curved edges and save you hours of hand-sanding every week.
