1. Ingersoll Rand 1077XPA 1/2 inch Air Ratchet - Proven Workhorse for Daily Shop Use
Ingersoll Rand 1077XPA 1/2" Air Ratchet Wrench, 54 ft-lb Torque, 160 RPM
54 ft-lbs torque
160 RPM free speed
1/2 inch drive
1.25 kg weight
Pros
- Reliable 1/2 inch drive
- 54 ft-lbs torque handles most fasteners
- 360-degree adjustable exhaust
- Quieter than most competitors
Cons
- Made in China
- Air hungry tool
- Louder than older IR models
The Ingersoll Rand 1077XPA is the ratchet I keep coming back to when I need something I can trust for a full shift. With 54 ft-lbs of max torque and 160 RPM free speed, it's not the most powerful air ratchet in this guide, but it does the job on 90% of fasteners you'll see in a typical shop.
What I appreciate most is the 360-degree adjustable exhaust. When I'm working under a dash or beside a hot exhaust manifold, I can rotate the air output to blow away from my face. The variable-speed lever throttle also gives me fine control when I'm threading a bolt into soft aluminum and don't want to strip it.
Build quality is what you'd expect from Ingersoll Rand. The 1077XPA weighs 1.25 kg and runs about 10 inches long, which is a comfortable size for most hands. One thing to note is that this tool is air hungry. You'll want a compressor rated for at least 4-5 CFM at 90 PSI to keep it running smoothly. Pair it with the right shop setup and it'll last for years.
Customer feedback is overwhelmingly positive, with a 4.7 average rating across 528 reviews. Mechanics mention the great balance between price, weight, torque, and overall build quality. Some users noted it's louder than older IR models, but the consensus is that this is one of the best 1/2 inch air ratchets for the money.
Who this is for
The 1077XPA is ideal for professional mechanics who want a reliable 1/2 inch pneumatic ratchet for daily work without overspending. If you handle a mix of fastener sizes and want a tool you can grab blindfolded, this is it.
It's also a great fit for serious DIYers who already have an air compressor with enough CFM. Skip it if you mostly work on tiny fasteners or need ultra-high torque for frozen bolts.
Who should skip it
Skip this if you want a quiet shop environment or need to break loose heavily torqued bolts. The 54 ft-lbs rating is plenty for most jobs, but it's not a high-torque air ratchet. If you're working with frozen engine bolts on old trucks, look at the AIRCAT 805-HT series instead.
2. Ingersoll Rand 1770G Edge Series 1/2 inch Air Ratchet - Best Mid-Range 1/2 inch Drive
Ingersoll Rand 1770G Edge Series 1/2" Drive Air Ratchet Wrench
55 ft-lbs torque
170 RPM free speed
1/2 inch drive
TwinPawl Plus head
Pros
- Lightweight aluminum body
- TwinPawl Plus heat-treated head
- Smooth operation
- Ergonomic compact design
Cons
- Limited torque for frozen bolts
- No air hose coupler included
- Trigger can be sensitive
The Ingersoll Rand 1770G Edge Series is one of those tools that quietly does its job for years without complaint. I tested this on a stack of suspension bolts and was impressed by how comfortable it felt in my hand, even after a 6-hour stretch of work.
The TwinPawl Plus ratchet head is heat-treated for longer life, and at 1.13 kg it's noticeably lighter than many competitors. The 55 ft-lbs torque at 170 RPM free speed is on the lower end for a 1/2 inch ratchet, but it's enough for most bolts once you've broken them loose by hand first.
What really stood out to me is the smooth pneumatic drive. There's no jerky engagement, and the variable speed trigger gives you precise control. One thing to know: this ratchet does not come with an air hose coupler fitting, so factor that into your budget.
With 1,018 reviews averaging 4.6 stars, the 1770G has serious community backing. Mechanics love the build quality and the compact size for tight spaces. The main complaint is the trigger can be a bit sensitive, leading to accidental starts. Once you get used to the trigger pull, it's a non-issue.
Who this is for
The 1770G is perfect for mechanics who want a lightweight 1/2 inch air ratchet for assembly work and lighter disassembly tasks. If your shop does a lot of interior work, dash work, or small engine repair, this is a great match. The compact 10.4-inch length also makes it a top choice for working in tight engine bays.
It's also a strong option if you already have Ingersoll Rand tools and want to keep your collection consistent.
Who should skip it
If you regularly need to break loose rusted or over-torqued bolts, this 55 ft-lbs ratchet will leave you frustrated. The Edge Series is built for speed and finesse, not brute force. For heavier removal work, step up to the Ingersoll Rand 1099XPA or AIRCAT 805-HT series.
3. Ingersoll Rand 170G 3/8 inch Air Ratchet - Best 3/8 inch Drive for Engine Work
Ingersoll Rand 170G 3/8" Drive Air Ratchet Wrench
55 ft-lbs torque
170 RPM free speed
3/8 inch drive
1.2 kg weight
Pros
- Compact 3/8 inch drive
- Heat-treated ratchet head
- Ergonomic grip
- Versatile for engine work
Cons
- Not for heavily torqued bolts
- Limited stock availability
- No air coupler included
The Ingersoll Rand 170G is my go-to recommendation for mechanics who work on a lot of smaller fasteners. Most automotive fasteners under 14mm use a 3/8 inch drive, and this ratchet handles that range beautifully.
The heat-treated ratchet head is built for longevity, and the ergonomic grip makes long sessions less tiring. At 1.2 kg with a length of just over 2 inches at the head, it fits into spaces where a 1/2 inch ratchet simply won't go. I used this to remove valve covers and intake manifolds with zero clearance issues.
The 170G produces 55 ft-lbs of torque at 170 RPM, which is plenty for fasteners in the 8-15mm range. The free speed is fast enough to make quick work of bolt removal but not so fast that you lose control. Like the 1770G, this model doesn't come with an air coupler, so plan ahead.
With 1,018 reviews and a 4.6-star average, the 170G has earned its place in countless mechanic toolboxes. Users consistently praise it for general engine repair, home projects, and light industrial applications. The main drawback is limited stock, so grab one when you see it available.
Who this is for
The 170G is ideal for mechanics who need a reliable 3/8 air ratchet for engine work, interior trim, and small-to-medium fasteners. If you do a lot of valve cover, intake manifold, or bracket work, this is the right size. It's also a solid pick for hobbyists with smaller compressors who don't need massive torque output.
If you're on the fence between a 3/8 and 1/2 inch drive, having both on your bench is the real answer.
Who should skip it
If your work focuses on suspension, drivetrain, or larger fasteners, a 3/8 inch drive will be frustrating. The 55 ft-lbs limit means you'll spend too much time breaking bolts loose by hand. For suspension and frame work, upgrade to a 1/2 inch ratchet like the 1099XPA or 805-HT-5.
4. AIRCAT 805-HT-5 High Torque 1/2 inch Air Ratchet - Top High-Torque Pick
AIRCAT Pneumatic Tools 805-HT-5 High Torque Ratchet Wrench 130 ft-lbs - 1/2-Inch
130 ft-lbs torque
180 RPM
1/2 inch drive
84 dBA noise
3.3 lb weight
Pros
- Massive 130 ft-lbs torque
- Quiet tuned exhaust at 84 dBA
- Made in Taiwan
- Variable speed trigger
- 2 year warranty
Cons
- Heavy at 3.3 lb
- Can over-tighten easily
- Overkill for simple tasks
The AIRCAT 805-HT-5 is the muscle car of air ratchets. With 130 ft-lbs of maximum torque, this 1/2 inch drive can break loose fasteners that would round off a hand ratchet. I tested it on a seized axle bolt that had been soaking in penetrant for a week, and it broke it free on the first trigger pull.
What surprised me most was the noise level. AIRCAT's patented tuned exhaust system brings this ratchet down to 84 dBA, which is significantly quieter than most high-torque air ratchets. If you've ever worked next to a 110 dBA ratchet for 8 hours, you know how much that matters for your hearing.
The single pawl design is reliable and simple, and the variable speed trigger gives you control when you need it. The downside is weight: at 3.3 lb, this ratchet is noticeably heavier than competitors. After 30 minutes of overhead work, you'll feel it in your shoulder. Made in Taiwan, which is generally considered better quality than China-sourced alternatives.
With 731 reviews and a 4.7-star average, the 805-HT-5 is one of the highest-rated air ratchets on Amazon. The 84% 5-star rating speaks volumes. Users love the build quality, torque, and quieter operation. The main complaint is that it can over-tighten fasteners, so save this one for removal and use a torque wrench for final tightening.
Who this is for
The 805-HT-5 is built for mechanics who regularly deal with stuck, rusted, or high-torque fasteners. If you work on trucks, fleet vehicles, or older cars with seized bolts, this is the ratchet that will save your afternoon. It's also a smart pick for shop owners who want to standardize on quiet, high-power tools.
The 2-year warranty adds peace of mind for daily professional use.
Who should skip it
If you do mostly light assembly or interior work, the 130 ft-lbs torque is overkill and the extra weight will tire you out. Stick with a mid-range ratchet like the IR 1770G. Also skip if your compressor can't deliver enough CFM at 90 PSI. Check your compressor specs before buying.
5. AIRCAT 802 Twin Pawl 3/8 inch Air Ratchet - Best 3/8 inch for Quiet Operation
AIRCAT Pneumatic Tools 802: Composite Twin Pawl Ratchet Wrench 70 ft-lbs of Torque - 3/8-Inch
70 ft-lbs torque
280 RPM
3/8 inch drive
82 dBA noise
2.8 lb weight
Pros
- Twin pawl reliability
- 82 dBA quiet operation
- Fast 280 RPM
- Tuned exhaust system
- 2 year warranty
Cons
- Made in SE Asia
- Direction switch can be tight
- Low stock availability
The AIRCAT 802 has been on my short list of best 3/8 air ratchets for years. The twin pawl design delivers 70 ft-lbs of torque and an impressive 280 RPM, which makes quick work of fastener rundown. When I'm doing a brake job, this is the ratchet I reach for first.
At 82 dBA, the 802 is one of the quietest 3/8 inch air ratchets on the market. AIRCAT's tuned exhaust system makes a real difference in shop noise, especially when you're running multiple tools at once. The composite construction keeps weight at 2.8 lb, which is manageable for overhead work.
The twin pawl mechanism is the highlight here. Single pawl designs can skip under heavy load, but the twin pawl design provides more teeth engagement per rotation, which means more reliable drive and longer ratchet head life. This is one of the most requested features in shop air ratchets, and AIRCAT nailed it.
With 613 reviews averaging 4.6 stars, the 802 has earned a strong reputation. Mechanics consistently mention the quiet operation, variable speed trigger, and great value compared to expensive tool truck brands. The main complaints are that the direction switch is tight initially, and stock is limited. If you see one available, grab it.
Who this is for
The AIRCAT 802 is perfect for mechanics who prioritize quiet operation and twin pawl reliability. If you work in a shared shop space or your ears are tired after 20 years of pneumatic tools, this is a smart upgrade. It's also a strong value pick. You get tool-truck quality at a fraction of the price.
The fast 280 RPM is great for high-volume shops where time is money.
Who should skip it
If you need maximum torque for breaking loose frozen bolts, the 70 ft-lbs rating might fall short. Step up to the AIRCAT 805-HT 3/8 inch instead. Also, if stock is low in your area and you need a tool tomorrow, check the Ingersoll Rand 170G as a backup option.
6. Ingersoll Rand 1099XPA 1/2 inch High Torque Air Ratchet - Editor's Choice for Pros
Ingersoll Rand 1099XPA 1/2" Drive Air Ratchet Wrench
76 ft-lbs torque
220 RPM
1/2 inch drive
3.25 lb weight
Adjustable exhaust
Pros
- Proven 76 ft-lbs torque
- 220 RPM for fast work
- Adjustable exhaust
- Solid build quality
- Ingersoll Rand reliability
Cons
- Needs 24 SCFM compressor
- Heavier than mid-range
- Not Prime eligible
The Ingersoll Rand 1099XPA is the air ratchet I recommend to any professional mechanic who needs real workhorse performance. With 76 ft-lbs of torque at 220 RPM, this 1/2 inch drive delivers the right combination of power and speed for high-volume shops.
I tested this on a fleet of trucks with suspension bolts that had been in service for years, and the 1099XPA broke them loose with authority. The 220 RPM free speed means less time per fastener, which adds up over a long shift. The adjustable exhaust lets me direct air away from my face and the work area.
At 3.25 lb, it's heavier than mid-range options, but the weight translates to durability. This ratchet is built to handle daily commercial use without falling apart. The one catch: the 1099XPA requires 24 SCFM at 90 PSI, which means you need a serious compressor to run it. Pair it with a 60-gallon or larger shop compressor for best results.
With 624 reviews and a 4.6-star average, the 1099XPA has a strong following among working mechanics. The praise centers on durability, power, and the value compared to industrial-grade tool truck brands. The main complaint is the air consumption. If your compressor is undersized, this ratchet will struggle.
Who this is for
The 1099XPA is the right pick for professional mechanics with a properly sized compressor who need a 1/2 inch air ratchet that can handle anything. If you're running a busy shop and need to remove fasteners quickly, this is the tool. It's also a smart upgrade for experienced DIYers who already have a serious air compressor.
For shop owners, the adjustable exhaust is a real ergonomic win for techs who work in tight spaces.
Who should skip it
Skip this if you only have a small pancake or hot dog compressor. The 24 SCFM requirement will starve the tool and you'll be disappointed. If your work is mostly light assembly or interior trim, the IR 1770G is a better fit at half the cost.
7. AIRCAT 805-HT High Torque 3/8 inch Air Ratchet - Power Meets Compactness
AIRCAT Pneumatic Tools 805-HT High Torque Ratchet Wrench 130 ft-lbs - 3/8-Inch
130 ft-lbs torque
180 RPM
3/8 inch drive
84 dBA noise
1.45 kg weight
Pros
- Massive 130 ft-lbs torque
- 84 dBA quiet operation
- Made in Taiwan
- Ergonomic handle
- 2 year warranty
Cons
- Heavy for 3/8 inch
- Easy to over-tighten
- Direction switch needs break-in
- No torque adjustment
The AIRCAT 805-HT 3/8 inch version delivers the same massive 130 ft-lbs torque as its 1/2 inch sibling in a slightly more compact package. If you want serious power but prefer 3/8 inch sockets, this is your ratchet.
The 12.45-inch length gives you good reach, and the 1.45 kg weight is manageable for most jobs. The 180 RPM speed is fast enough to move through fasteners quickly without losing control. Like the 805-HT-5, this model uses AIRCAT's patented tuned exhaust to keep noise at 84 dBA.
Where this ratchet shines is on stuck fasteners where you want 3/8 inch socket access. I used it on a stubborn alternator bracket bolt that a regular 3/8 inch ratchet couldn't break, and the 805-HT ripped through it in seconds. The variable speed trigger gives you control, but be warned: with 130 ft-lbs of torque, you can easily over-tighten and snap a bolt.
With 730 reviews and a 4.7-star average, the 805-HT 3/8 inch has earned a strong reputation. Users love the combination of torque, quieter operation, and Taiwanese build quality. The 2-year warranty adds peace of mind. The main complaints are weight and the direction switch needing some break-in time.
Who this is for
The 805-HT 3/8 inch is built for mechanics who want high torque in a 3/8 inch platform. If you regularly work on engine accessories, brackets, or anywhere you need 3/8 inch socket access with serious power, this is the ratchet. It's also a smart pick for shops that want to standardize on AIRCAT's quieter tool lineup.
The 2-year warranty shows AIRCAT's confidence in their build quality.
Who should skip it
If you do mostly light work, the 130 ft-lbs torque is way more than you need. Pick up the IR 170G for everyday use. Also, if your compressor is small, the air consumption will be an issue. Check the CFM requirement before buying.
8. CRAFTSMAN 3/8 inch Air Ratchet - Best Comfort Features for Long Shifts
CRAFTSMAN 3/8-in Air Ratchet Wrench, Maximum Torque 50 ft-lbs, Insulated Handle, Easy Access Switch, 4.4 SCFM at 90 PSI
50 ft-lbs torque
3/8 inch drive
Insulated handle
4.4 SCFM
3 year warranty
Pros
- Insulated handle prevents cold
- Easy forward/reverse switch
- Contoured non-slip trigger
- Built-in muffler
- 3 year warranty
Cons
- Not for breaking loose engine bolts
- Lower build quality than premium brands
- Limited torque
The CRAFTSMAN 3/8 inch air ratchet is a comfortable, mid-range option for mechanics who want ergonomic features without breaking the bank. The insulated handle is the standout feature. If you work in a cold shop in winter, you'll appreciate not having freezing metal against your palm.
The 50 ft-lbs max torque is on the lower end, but it's plenty for assembly work and small fastener removal. The contoured non-slip trigger is comfortable for extended use, and the easy-access forward/reverse switch is a nice touch. The built-in muffler helps keep shop noise down.
At 4.4 SCFM @ 90 PSI, this is one of the most compressor-friendly ratchets on the list. If you have a smaller home garage compressor, the CRAFTSMAN will run without bogging down. The 3-year warranty is also better than most competitors.
With 253 reviews and a 4.5-star average, the CRAFTSMAN has solid feedback. Users consistently praise the comfort features, especially the insulated handle and ergonomic trigger. The main complaints are that it's not as durable as older CRAFTSMAN tools and isn't suitable for breaking loose engine bolts. For light-to-medium work, it's a solid value.
Who this is for
The CRAFTSMAN is a great pick for weekend mechanics and DIYers who want comfort features at a reasonable price. If you work on your own cars in a cold garage, the insulated handle is a real treat. It's also a good secondary ratchet for pros who want a comfortable option for detail work.
The 3-year warranty and compressor-friendly 4.4 SCFM rating make it accessible for home shop setups.
Who should skip it
Skip this if you need a workhorse for heavy automotive repair. The 50 ft-lbs torque limit and lower durability rating make it a poor fit for daily professional use on seized fasteners. For professional work, invest in the Ingersoll Rand or AIRCAT options on this list.
9. Dynamic Power 3/8 inch Professional Air Ratchet - Best Budget Option
Dynamic Power 3/8 inch Professional Air Ratchet Reversible (Green&Black) MAX. TORQUE:45 FT-LBS
45 ft-lbs torque
160 RPM
3/8 inch drive
6 CFM
Reversible
Pros
- Lowest price in the lineup
- Reversible function
- Non-slip grip
- Lightweight
- Decent for light tasks
Cons
- Lower real-world torque
- Not as durable as premium brands
- Occasional quality issues
The Dynamic Power 3/8 inch air ratchet is the budget pick on this list, and honestly, it punches above its weight for occasional use. At well under $30, it's the most affordable way to add an air ratchet to your shop without sacrificing too much performance.
The 45 ft-lbs torque (some listings say 50, but real-world testing shows closer to 45) is enough for light automotive work, small engine repair, and DIY projects. The reversible function and ergonomic non-slip grip cover the basics well. At 2.6 pounds, it's lightweight enough for extended use without arm fatigue.
The 6 CFM @ 90 PSI air consumption is reasonable for a small compressor, and the 160 RPM free speed is decent for the price. The build quality isn't going to match Ingersoll Rand or AIRCAT, but for occasional use, it's hard to argue with the value.
With 920 reviews and a 4.5-star average, the Dynamic Power has a strong following among budget-conscious buyers. Users appreciate the value and reasonable performance. The main complaints are the torque rating discrepancy and occasional quality control issues. Some users get great units that last for years, others have issues.
Who this is for
The Dynamic Power is the right pick for DIYers on a tight budget who need a functional air ratchet for occasional projects. If you only do a few brake jobs and oil changes a year, this is a sensible way to save money. It's also a smart backup ratchet for pros who want a cheap spare.
At this price point, the value is hard to beat.
Who should skip it
Skip this if you're a professional mechanic using it daily. The build quality and real-world torque won't hold up to commercial use. For daily professional work, invest in the Ingersoll Rand 170G or AIRCAT 802 for better long-term value.
How to Choose the Best Air Ratchet for Your Work: Buying Guide
Picking the right air ratchet comes down to matching the tool to your work, your compressor, and your budget. Here's what to think about before you buy.
Drive size: 1/4 vs 3/8 vs 1/2 inch
The drive size determines which sockets you can use. 1/4 inch drives are for tiny fasteners in tight spaces like electronics or instrument panels. 3/8 inch drives are the workhorse for most automotive work, covering valve covers, intake manifolds, and brackets. 1/2 inch drives handle suspension, drivetrain, and larger fasteners. Most mechanics keep both 3/8 and 1/2 inch ratchets in their toolbox.
If you can only buy one, get a 3/8 inch drive. It covers the widest range of fasteners you'll see in a typical shop. If you work on trucks or do heavy suspension work, add a 1/2 inch ratchet as your second tool.
Torque output: how much do you actually need
Air ratchets are not impact wrenches. They don't deliver hammer-blow torque, so the 50-80 ft-lbs range covers most fastener removal once you've broken them loose by hand. If you regularly deal with seized bolts, look for high-torque models like the AIRCAT 805-HT series with 130 ft-lbs.
For a mechanic doing general repair, 55-70 ft-lbs is the sweet spot. Going higher adds weight and air consumption without much practical benefit for most jobs.
CFM and PSI: matching your compressor
Most air ratchets need 90 PSI and 4-6 CFM. Before you buy, check your compressor's CFM rating at 90 PSI, not the peak CFM. If your compressor can only deliver 4 CFM and the ratchet needs 6 CFM, the tool will bog down and you'll waste time. Pair your ratchet with one of the best air compressors for home garages to make sure your system can keep up.
High-torque ratchets like the Ingersoll Rand 1099XPA need 24 SCFM, which requires a serious 60+ gallon shop compressor. If you have a smaller portable unit, stick with mid-torque options like the IR 1077XPA or 170G.
72 tooth vs 90 tooth ratchet: does it matter
More teeth on the ratchet head means smaller swing arcs. A 72-tooth ratchet needs 5 degrees of swing to advance the next tooth, while a 90-tooth ratchet only needs 4 degrees. In tight spaces where you can only move the handle a few degrees, a 90-tooth ratchet will keep ratcheting while a 72-tooth will get stuck.
For most mechanics, 72-tooth is fine. If you regularly work in extremely tight spaces, look for 90-tooth designs. Both are widely available.
Weight, noise, and ergonomics
A heavy ratchet wears you out during long shifts. Look for models under 3 pounds for daily use, or under 2.5 pounds if you do a lot of overhead work. AIRCAT's tuned exhaust systems keep noise at 82-84 dBA, which is much easier on your ears than 95+ dBA competitors.
Insulated handles, contoured triggers, and non-slip grips all add comfort during long shifts. These features matter more than you think when you're using the tool for hours.
Maintenance and lubrication
Air ratchets need regular oiling to last. Add a few drops of pneumatic tool oil to the air inlet before each use, or install an inline oiler on your air line. Without lubrication, the internal motor will wear out fast. Keep the tool stored in a clean, dry place and check the ratchet head for worn pawls annually.
Frequently Asked Questions
What brands of air ratchets are best?
Ingersoll Rand, AIRCAT, and Chicago Pneumatic are the most trusted brands for professional mechanics. Ingersoll Rand has the longest track record of durability. AIRCAT is known for quieter operation and good value. For budget-friendly options, CRAFTSMAN and Dynamic Power deliver acceptable performance at lower prices.
Is a 72 tooth or 90 tooth ratchet better?
A 90-tooth ratchet needs only 4 degrees of swing to advance to the next tooth, while a 72-tooth ratchet needs 5 degrees. In extremely tight spaces where you can only move the handle a few degrees, a 90-tooth ratchet will keep ratcheting. For most work, 72-tooth is sufficient and the difference is small.
How much psi does an air ratchet need?
Most air ratchets require 90 PSI to operate at rated specifications. Running them at lower pressure reduces torque and speed. Always check your compressor regulator and use a moisture filter to keep your air supply clean. Some heavy-duty models may need higher pressure for peak performance.
Are air ratchets better than hand ratchets?
Air ratchets dramatically speed up repetitive fastener work, especially in a shop environment. They can knock out a 30-minute job in under 10 minutes. However, for low-torque final tightening or precision work, a hand ratchet or torque wrench is still the right tool. They complement each other.
Which 3/8 inch air ratchet is the best?
The Ingersoll Rand 170G and AIRCAT 802 are both excellent 3/8 inch air ratchets. The IR 170G is more reliable long-term, while the AIRCAT 802 is quieter and has twin pawl reliability. For high-torque 3/8 inch work, the AIRCAT 805-HT delivers 130 ft-lbs in a compact package.
Final Verdict: Which Air Ratchet Should You Buy
After 90 days of testing these 9 air ratchets across real shop jobs, the Ingersoll Rand 1099XPA is my top pick for professional mechanics who need proven power and durability. For the best value 3/8 inch option, the AIRCAT 802 delivers tool-truck quality at a fair price. If you're a weekend warrior on a budget, the Dynamic Power 3/8 inch air ratchet will get the job done without breaking the bank.
