The best air ratchets, compared.
Top pick: Draper 84126 Best value: US Pro AT005 – Highest value part among the other listings: about £28.22, with 40 Nm, 250 rpm, 2.5 cfm and a 1/4 inch BSP inlet stated, and 4.1 from 37 ratings. Updated October 2026.
An air ratchet spins a square drive on compressed air so you can run nuts off without the swing of a spanner. In the UK you buy one when a compressor is in the garage, for a faster rundown on covers, radiators, filters and small-engine fasteners. Snug the nut, then finish a critical fastener with a torque wrench. You tell a suitable air ratchet by the square, the stated torque at about 90 psi (6.2 bar), the air the compressor must deliver, and whether the head fits the bay. Squares are 1/4 inch, 3/8 inch or 1/2 inch, matching the socket rather than a power rank. A short head reaches a fastener a long body cannot. Match stated air demand to delivered flow. Tank litres store air. They are not the flow. A 1/4 inch BSP fitting and a 1/4 inch NPT fitting do not seal on each other. Keep the trigger off until the hose is on, and do not blow compressed air at your skin. Drive, torque and air are set out in the [air ratchet buying guide](/hub/hand-tools/air-ratchet/sub/air-ratchet-buying-guide).

Question 1 of 2
What is the job?
The Draper 84126 is a 3/8 inch ratchet with a stubby yoke, a 4-speed rear regulator and a 1/4 inch BSP inlet on a 360-degree rotating connector. The listing mass is 500 g and the size line is 30 × 4 × 4 cm. It claims a lightweight aluminium housing, a soft-grip handle and a middle exhaust, and the bullets describe radiator, spark plug and pump work. The star line is 5.0 from 3 ratings, and there is no review text, so those stars do not describe a job. Torque, free speed, air consumption and operating pressure are all missing from the listing. Direction change is not named either. The August 2025 manual states 85 Nm, 4 cfm, 1.21 kg and impact sockets only. The 500 g amazon.co.uk mass is not that manual mass, so it is not confirmed here.
Pros
Cons
Best for: You want a short Draper 3/8 inch body with a stated BSP inlet and you will read the manual for torque.
Less suitable: A choice you want backed by a written review, or a mass you take from the amazon.co.uk line alone.
Specifications
Common questions
What torque does this Draper listing state?
The amazon.co.uk page does not. It states a 3/8 inch drive, a stubby yoke, a 4-speed regulator and a 1/4 inch BSP inlet. The August 2025 manual states 85 Nm.
Is there review text?
The star line is 5.0 from 3. There is no review body, so those stars do not describe a job.
The Durlo page lists a 265 mm ratchet with a forward and reverse switch on the head, for small-engine, headlight and filter work. The drive line says a 3/8 inch square and also 10 mm, and torque, free speed and air consumption are all absent. The only rating is 5.0 from one review, marked France on 17 January 2026, and the text is the single word Super. That review names no job and no fault. The listing mass of 0.01 g is not a usable weight for a 265 mm tool, so the mass stays unknown. Country of origin is China, and the page does not itemise a case, oil or sockets. A price near the US Pro AT005 does not make the two listings the same tool.
Pros
Cons
Best for: You already know which sockets fit this head and you are choosing on the price.
Less suitable: A job that needs a stated torque, a known weight, or a review that describes the work.
Specifications
Common questions
What drive does the Durlo use?
The listing says a 3/8 inch square head and also 10 mm. It does not state torque, free speed or air consumption.
How much does it weigh?
The listing mass is 0.01 g. That figure is not usable, so weight is unknown from this page.
The Ingersoll Rand 1105MAX-D2 is a 1/4 inch mini listed at 40.7 Nm in the title and 41 Nm in the torque field, with 300 rpm, 650 g and a length of 7.36 inches. Across 275 amazon.co.uk ratings the line is 4.6, though the early texts are from Sweden, the United States, France, Canada and Belgium. Reviewers call it light enough for tight spaces and say the rundown is fast, and some say they use a speed regulator. One professional user says a previous tool of this type lasted more than 15 years. Torque is described as short of a full-size ratchet, and the trigger is harder to feather than some older tools. Two French reviews report an air leak at the adjustment collar, and one of those ended in a refund because of stock. Air consumption, operating pressure and the inlet thread are not on this row. A UK dealer sheet lists average air use of 3.5 cfm, 20 cfm at free speed, a 1/4 inch NPT inlet and 88.9 dB(A). Those figures are not on this amazon.co.uk row, and that NPT inlet does not seal on a BSP hose.
Pros
Cons
Best for: You run 1/4 inch sockets in a tight bay and you can live with a mini's 40.7 Nm.
Less suitable: A fastener that needs the 88 Nm listing in this set, or a hose you have not matched to 1/4 inch NPT.
Specifications
Common questions
What size is the 1105MAX-D2?
The listing is a 1/4 inch mini at 40.7 Nm, 300 rpm and 650 g. Air consumption and the inlet thread are not on this amazon.co.uk row.
Are the reviews British?
The star line is 4.6 from 275. The review texts captured in the file are from outside the United Kingdom.
The Ingersoll Rand 1207MAX-D3 is a 3/8 inch ratchet listed at up to 88 Nm and 1.42 kg, with a forward and reverse collar and a variable speed regulator. The star line is 4.4 from 115 ratings. Two United Kingdom texts call it powerful, if not the fastest, and good quality, while the longer texts are mostly from the United States and Canada. Reviewers mention the twist collar and an adjustable exhaust. The collar is sticky until air is connected, in more than one review, and one user found the inlet blocked by cardboard before the tool made full power. It is heavier than a small ratchet in one review, and an identification tag came off easily in another. Free speed and air consumption are not on this row, and the length field reads 0.38 inches, which is not a usable overall length. A UK seller page lists 275 mm, average air use of 4 cfm and 23 cfm at free speed. Use that length, not the 0.38 inch field.
Pros
Cons
Best for: You want the 88 Nm figure in this set on a 3/8 inch drive and you can check the collar once air is connected.
Less suitable: A very tight bay where 1.42 kg gets in the way, or a spec sheet that must quote free speed from the amazon.co.uk row alone.
Specifications
Common questions
How much torque does the 1207MAX-D3 listing state?
Up to 88 Nm, on a 3/8 inch drive, at 1.42 kg. Free speed and air consumption are not on this amazon.co.uk row.
Can you use the listing length?
No. The length field reads 0.38 inches, which is not a usable overall length. A UK seller page lists 275 mm.
What do the UK reviews say?
Two UK texts call it powerful and good quality. They do not describe a fault.
The Ingersoll Rand 105-D3 is a 3/8 inch ratchet at 34 Nm and 250 rpm, weighing 640 g and measuring 18.5 cm. It has 4.3 from 30 amazon.co.uk ratings, and the review texts are from Canada and the United States, with no United Kingdom body in the file. Reviewers use the small body in tight places, one calls it quieter than the tool it replaced, and one reports daily workshop use when it is oiled. The same file describes it as a 1/4 inch body with a 3/8 inch anvil, and light for sockets much over 13 mm. One review puts the power below the printed 34 Nm, the trigger is called too easy and has no catch, and one professional user says the head or housing comes loose in daily use. Air consumption, pressure and the inlet thread are not stated on this row. The Ingersoll Rand GB page lists 3 cfm average, 18 cfm at free speed and 81.8 dB(A). Those figures are not on the amazon.co.uk row, and the review texts are not British opinion.
Pros
Cons
Best for: You want a short 3/8 inch Ingersoll Rand around 34 Nm for access work, and you will keep it oiled.
Less suitable: Sockets much over 13 mm, or a job that needs the 61 Nm or 88 Nm listings in this set.
Specifications
Common questions
Is the 105-D3 a full-size 3/8 inch ratchet?
The listing gives 34 Nm, 250 rpm, 640 g and 18.5 cm. One reviewer says it is a mini body with a 3/8 inch anvil.
Does the listing state air consumption?
No. Torque, free speed, mass and length are stated. Air consumption, pressure and the inlet thread are not on this row.
The US Pro AT005 is a stubby 3/8 inch ratchet at 180 mm and 624 g, listed at 40 Nm and 250 rpm. The page also says 30 ft lb, and average air use is 2.5 cfm at 90 psi through a 1/4 inch BSP inlet. The star line is 4.1 from 37 ratings, and the UK-marked reviews talk about size, speed and noise. Buyers use it on valve covers and timing covers, and they call it fast on fasteners that are not seized. One buyer treats the modest torque as less likely to snap a bolt. It is painfully loud in more than one UK review, and one buyer stopped using it because of the noise. One original unit failed, and the seller sent a replacement the same day. Direction change and speed control are not named. It is the best value in this set because the value part is the highest of the listings that are not the top score.
Pros
Cons
Best for: You need a short 3/8 inch ratchet for covers and fasteners that are not seized, and you already wear hearing protection.
Less suitable: A seized bolt, or a garage where this level of noise is a problem.
Specifications
Common questions
Is the US Pro AT005 a short ratchet?
Yes. The listing calls it a stubby 3/8 inch drive at 180 mm, with 40 Nm and 250 rpm.
What air fitting does it use?
1/4 inch BSP, and 2.5 cfm at 90 psi.
What do UK reviews mention?
Tight access on engine covers, modest torque, and noise. One buyer received a same-day replacement.
The Sealey SA21/S is a 1/2 inch ratchet listed at 61 Nm, with a bullet that also states 45 lb ft, on a 90 psi supply at 5 cfm. It weighs 1.21 kg and is 26.5 cm long, with a hardened steel anvil, a twist reverse and trigger-operated power control. Across 22 amazon.co.uk ratings the line is 4.1, and the file holds three United Kingdom texts. One calls it top quality for workshop use. Another had to strip and relubricate it after it stopped on first use, and it then worked. A third describes the noise as unbearable beside their other air tools and would not use it. Free speed and the inlet thread are not on this row. The Sealey manual states 150 rpm, 95 dB(A), 2.9 m/s² and a 1/4 inch BSP inlet. Quote the manual for those figures. They are not the amazon.co.uk free-speed line.
Pros
Cons
Best for: You want a 1/2 inch workshop ratchet around 61 Nm and you will oil it before the first job.
Less suitable: A shared workshop where that noise is a problem, or a first job you cannot interrupt to relubricate.
Specifications
Common questions
Does the Sealey SA21/S reverse?
Yes. The listing names a twist reverse mechanism and a hardened steel anvil.
What air supply does the listing state?
90 psi and 5 cfm. Free speed and the inlet thread are not on this amazon.co.uk row. The manual states 150 rpm and 1/4 inch BSP.
What do UK reviews say?
Three UK texts are in the file: workshop quality, a first-use strip and relube, and noise described as unbearable.
The Draper 84122 is a 1/2 inch ratchet listed at 85 Nm, with a 4-speed rear regulator, an aluminium housing and a claimed soft-grip handle. The listing mass is 500 g and the length is 0.29 m, and the bullets describe radiator removal and replacement. The star line is 3.0 from one rating, and there is no review text, so that star does not say what failed. Free speed, air consumption, operating pressure and the inlet thread are not on this row. Country of origin is China. The stated 85 Nm sits next to the 88 Nm Ingersoll Rand in this set, at about £39.81 and without that tool's written reviews. The manual states 1.22 kg, so the listing mass of 500 g is not confirmed. The same manual says this is not a torque wrench and that you should use impact sockets, not chrome hand sockets.
Pros
Cons
Best for: You want a stated 85 Nm on a 1/2 inch Draper and you will judge the tool yourself.
Less suitable: A bay where you need a written review before you connect the hose.
Specifications
Common questions
What torque does the Draper 84122 listing state?
85 Nm, on a 1/2 inch drive, with a 4-speed regulator. Air consumption and the inlet thread are not on this row.
Is there a written review?
The star line is 3.0 from 1. There is no review body, so that star does not say what failed.
Eight air ratchets on amazon.co.uk were scored from the star line, the review count, what the review texts describe, and a value part for price and printed figures. The top pick is the highest total. The best value is the highest value part among the other listings. There is no lab test. A newton-metre figure is the figure the listing prints.
Star rating
35%The amazon.co.uk rating divided by 5, then multiplied by 35. A 4.6 contributes 32. A 5.0 still scores 35 on this part, and a thin sample is scored separately.
Review sample
20%200 or more ratings score 12. From 100 to 199 scores 8. From 20 to 99 scores 4. Under 20 scores 1. A single rating cannot outrank a large sample on this part.
Use in the reviews
30%What the review texts describe: tight access, a named job, a fault in more than one review, or no review body at all. Stars with no written review stay low on this part.
Value in this set
15%Shelf price, plus a printed torque, free speed, air figure or named control. A conflicting drive line, or a missing torque, is deducted once. This part names the best value. It does not name the top pick.
Use the square you already own, then the stated torque, then the air. The notes below apply those checks to the eight amazon.co.uk listings read on 20 October 2026. Shelf prices and star lines can move. The checks do not.
An air ratchet is a pneumatic spanner. Compressed air turns a square drive so the socket runs a nut off without the arc of a hand ratchet. UK buyers are home mechanics and workshops that already own a compressor. The stable checks are the job and the stated torque, the square, the length and mass of the head, the air at about 90 psi (6.2 bar), and the inlet thread. Cover bolts are not the same job as an 80 Nm fastener, and a rusted suspension bolt is a third job again.
A tank stores air. It does not tell you the flow the compressor can hold at 90 psi. Match the model's cfm to delivered flow. Do not guess a written scheme for a work receiver from the litre figure either.
A 1/4 inch BSP fitting and a 1/4 inch NPT fitting do not seal on each other. Sealey, Draper and US Pro threads that are named are BSP. A UK dealer lists the 1105MAX-D2 as NPT. Check the thread before the hose is made up.
A printed maximum is the listing figure at the stated pressure. It is not a wheel-nut torque. The Draper manual says to snug the nut and finish a critical fastener with a hand torque wrench. Trust neither a 0.01 g mass nor a 0.38 inch length when the figure is absurd.
Read the newton-metre figure against the fastener, not against the square. Cover bolts, filter housings and small-engine work are a different duty from a rusted suspension bolt. The Draper 84122 listing states 85 Nm and the 84126 listing states none. The August 2025 manual for those two states 85 Nm and says the tool is not a torque wrench. The US Pro AT005 states 40 Nm, and UK reviews use it on valve covers and timing covers, not on seized bolts.
Match the model's air figure to delivered compressor flow at about 90 psi (6.2 bar). Tank litres are storage. The US Pro AT005 states 2.5 cfm at 90 psi through a 1/4 inch BSP inlet. The Sealey SA21/S states 5 cfm at 90 psi. Its manual adds 150 rpm, 95 dB(A) and 2.9 m/s², which the amazon.co.uk row does not print as free speed. A UK dealer sheet for the 1105MAX-D2 lists average air use of 3.5 cfm, 20 cfm at free speed, a 1/4 inch NPT inlet and 88.9 dB(A).
Three typical situations, each with a recommendation from this comparison.
You already have a compressor and 3/8 inch sockets, and the jobs are covers and radiators. The US Pro AT005 is about £28.22, with 40 Nm, 250 rpm, 2.5 cfm and a 1/4 inch BSP inlet, and 4.1 from 37 ratings. UK reviews cite valve covers, timing covers and noise. If you look at the Draper 84126, check the manual against the amazon.co.uk mass before you treat 500 g as the tool weight.
You want a 1/2 inch anvil and you can live with the noise notes. The Sealey SA21/S is about £40.53, listed at 61 Nm, 5 cfm and 90 psi, with 4.1 from 22 ratings. Three UK texts cover workshop use, a first-use strip and relube, and noise one buyer called unbearable.
You are spending in the band from about £148 to about £217 and you will match inlet thread and free-speed air on the maker sheet. The Ingersoll Rand 1105MAX-D2 is the top pick on score. A UK dealer lists it as 1/4 inch NPT, which does not seal on a BSP hose. The amazon.co.uk row does not print air consumption.
The top pick is the Ingersoll Rand 1105MAX-D2. It has the highest score in this set, from 4.6 across 275 amazon.co.uk ratings, and reviewers describe tight access and a fast rundown. It is a 1/4 inch mini listed at 40.7 Nm and about £196.70. Torque is described as short of a full-size ratchet, two French reviews report an air leak at the adjustment collar, and air consumption is not on the amazon.co.uk row. The best value is the US Pro AT005 at about £28.22. It has the highest value part, with 40 Nm, 250 rpm and 2.5 cfm stated, and 4.1 from 37 ratings. UK reviews use it on valve covers and timing covers and also call it painfully loud. One original unit failed and was replaced the same day. The other six listings have no award. None of these scores is a lab test.
US Pro AT005
Highest value part among the other listings: about £28.22, with 40 Nm, 250 rpm, 2.5 cfm and a 1/4 inch BSP inlet stated, and 4.1 from 37 ratings.
