The best Air nibblers, compared.
Top pick: Walfront air nibbler 2800 RPM Best value: Draper 70835 air nibbler – Stated 1.5 mm steel at about £35.56, with 4.2 from 57 reviews, the largest count here. Updated October 2026.
An air nibbler is a pneumatic punch-and-die cutter for sheet metal. You use it for curves, internal holes, and profiled sheet when you already have a compressor and you do not want grinder sparks. Cordless nibblers and drill attachments are a different category. The listing states steel up to 1.5 mm, 90 psi and 4 cfm, and a punch and die that rotates through 360 degrees. One reviewer cut 1.5 mm mild steel easily. Another returned a unit that missed that thickness at 90 psi. The maker states 9.8 cfm, and more than one review says the connector was not a standard 1/4 inch BSP fitting. The [air nibbler buying guide](/hub/cutting-tools/air-nibbler/sub/air-nibbler-buying-guide) sets thickness, air, inlet, and spares in that order.

Personal buying guide
Question 1 of 2
What do you need the listing to state?
The Walfront listing, at £36.14 and 4.4 from 17 reviews, is the highest star line in this set, and it does not state a steel thickness. Reviewers have used it on box-profile roofing, and on van windows, vents and an electrical hook-up point. One short review simply says the performance was excellent. The same small set of reviews describes a head that is hard to see, saw-toothed edges that needed a sander, and a stall that restarted only after the tool was backed out and struck on the bench. One buyer cut thin aluminium and then failed on 0.5 mm steel. Crescent waste is flung around the work. The amazon.co.uk image file is the same file used on the Cocoarm listing, so the photograph does not show that the two tools differ.
Pros
Cons
Best for: You are cutting thin automotive sheet you can test on scrap, and you accept that the capacity is not printed.
Less suitable: You need a stated millimetre, a spare you can order by part number, or a cut that stays on the line.
Specifications
Common questions
What thickness can it cut?
The listing does not state a thickness. One UK review says it coped with sheet steel up to 1 mm. Another says it failed on 0.5 mm steel.
How is the blade changed?
The bullets say to unscrew the button on the head, open the lid, and replace the blade.
Is it cordless?
The title calls it an air nibbler and a pneumatic cutting tool. The listing does not name a battery or a mains lead.
Across 57 amazon.co.uk reviews the Draper 70835 is the most reviewed air nibbler in this set, listed at £35.56 with a stated cut of up to 1.5 mm steel. Reviewers who stayed on flat sheet describe quick cuts, including 1 mm mild steel and, in one test, 2 mm aluminium described as close to the jaw limit. One buyer used it on steering brackets for a vintage Land Rover. The listing weight is 960 g, with an adjustable die and a front exhaust. The amazon.co.uk page does not print cfm or inlet size. Draper’s own page states 9.8 cfm, 3,800 strokes per minute and a 1/4 inch BSP inlet, and more than one review says the connector was not a standard 1/4 inch BSP fitting. Air use is called relatively high, and at least one buyer stalled at 1.5 mm or stopped after about five minutes on 1 mm steel.
Pros
Cons
Best for: You have compressor output for a tool the maker rates at 9.8 cfm and you want a named 1.5 mm steel nibbler near £36.
Less suitable: You run a small compressor, you need a standard 1/4 inch BSP plug out of the box, or the sheet is profiled.
Specifications
Common questions
What steel thickness does the listing state?
The amazon.co.uk bullets say it cuts up to 1.5 mm steel. Air consumption, pressure and inlet size are not in the listing text, so those fields are not shown.
Can the head follow a curve?
The listing says the die is adjustable for curves, corners and straight lines, and that a front exhaust directs air away from the work.
What do buyers mention about fitting the air line?
More than one review says the connector was not a standard 1/4 inch BSP fitting. Others mention high air use and sharp chips.
The LiebeWH is the lowest price in this set at £34.32, listed at 2,800 rpm with a 1 mm capacity that the bullets apply to steel, aluminium, stainless and barbed wire in one line. The inlet is printed as 1/4 and the working pressure as 8kg, without saying BSP or psi. Across 3 amazon.co.uk reviews the score is 4.2, and the only written review says it cut window holes in a Transit campervan and did the job. There is no criticism in that saved review, which is too small a sample to treat as a pattern. The listing weight is 880 g. A 1 mm line that also names stainless is not a separate stainless rating, and the listing does not name a spare punch.
Pros
Cons
Best for: You are cutting about 1 mm automotive skin, you can scrap-test first, and the shelf price matters more than a service record.
Less suitable: You need 1.5 mm steel, a published cfm figure, or more than one written UK review.
Specifications
Common questions
What does the listing say it will cut?
The bullets state a 1 mm capacity for steel plate, aluminium plate, stainless steel plate and barbed wire.
What air connection is printed?
The listing says the inlet port is 1/4 and the working pressure is 8kg. It does not say BSP or psi.
Is there a UK review?
One UK review says it cut window holes in a Transit campervan. No criticism is written in the saved reviews.
The Cocoarm listing shows 4.0 from 1 review at £37.73, and the saved listing contains no review text at all. The title states 2,800 rpm and a hardened blade in a hard alloy case, and both the item and the package are listed at 850 g. No steel thickness, air consumption, pressure or inlet thread is printed. Package dimensions are 20 x 11 x 4 cm. The product image is the same amazon.co.uk file as the Walfront, so you cannot tell the two apart from the photograph. With one star and no sentences, there is nothing here to confirm a cut, a stall or a fitting. First listed on 25 December 2024, it is the newest row in this set and the least documented.
Pros
Cons
Best for: Only as a spare row beside listings that state a thickness, and only if one review with no written text is enough.
Less suitable: You need a stated capacity, a UK spare, or any written account of a cut.
Specifications
Common questions
What cutting capacity is stated?
None. The bullets describe a hardened blade and an alloy housing and do not give a thickness.
How many written reviews are in the saved listing?
The listing shows 4.0 out of 5 from 1 review. The saved listing has no review text, so praised and criticised points are not available.
Is a weight given?
Yes. Item weight and package weight are both 850 g. Package dimensions are 20 x 11 x 4 cm.
The Sealey SA28 is listed at £43.19 for steel up to 1.5 mm, with a stated air supply of 90 psi and 4 cfm and a punch and die that rotates through 360 degrees. Across 33 amazon.co.uk reviews it sits at 3.9. Buyers who got it running call it surprisingly powerful, and one says it cuts 1.5 mm mild steel easily and suits vehicle work. The listing weight is 798 g. Another buyer returned a unit that would not cut 1.5 mm mild steel at 90 psi, so the stated maximum is not a guarantee on every sheet. A separate review describes a BSP inlet plug screwed in so tightly that the threads galled and needed a tap. The technical table also lists the power source as AC, which contradicts the air-supply line on the same page.
Pros
Cons
Best for: You want a 1.5 mm steel nibbler whose air demand is printed as 4 cfm at 90 psi, and you can check the inlet thread before the first cut.
Less suitable: You need the first sheet to match 1.5 mm without a scrap test, or you will not deal with a seized BSP plug.
Specifications
Common questions
What air supply does the listing ask for?
The bullets state 90 psi and 4 cfm. The technical table lists the power source as AC. Both lines are on the same listing.
Can the punch and die be turned?
The listing says the punch and die may be rotated through 360 degrees to help access.
Did buyers reach 1.5 mm steel?
One review says it cuts 1.5 mm mild steel easily. Another says it did not manage 1.5 mm mild steel at 90 psi and was returned.
The Ingersoll Rand 325B is the dearest tool here at £133.60, listed for steel up to 1.2 mm at 4,200 strokes per minute and a 6.5 mm cutting radius. Across 15 amazon.co.uk reviews it sits at 3.7. Reviewers who got a cut describe a smooth edge, easy work in 0.050 inch sheet aluminium, and a straight line when a guide is held against the snout. The same reviews say the cut only becomes visible about a quarter of an inch behind the punch, so the line wanders without that guide. One buyer found no pneumatic fitting in the box and moved one from another tool. Another unit would not run out of the box despite pressure and oil, and one review calls the tool slow and heavy on air. The maker’s sheet, not the amazon.co.uk wattage line, states about 4 cfm on average and 17 cfm at load, with a 1/4 inch NPTF inlet.
Pros
Cons
Best for: You want the published 6.5 mm radius on sheet up to 1.2 mm, and you will fit an NPT adapter and cover the load air figure.
Less suitable: You want a BSP tool under £50, or you expect the box to include a UK air fitting.
Specifications
Common questions
How thick a cut does the listing claim?
The bullets say steel up to 1.2 mm (18-gauge), at up to 4,200 BPM, with a tight radius of 6.5 mm. CFM and inlet thread are not in the listing.
Does the box include an air fitting?
One review says the pneumatic attachment was not included and had to be taken from another air tool. The included-components line says 1 piece.
What is the wattage line on the listing?
The technical table prints 15 KW. No other wattage is given in the listing. The power source line says air powered.
Six amazon.co.uk air nibblers were scored from the listings dated 19 October 2026. Prices, star lines, and review themes come from those pages. Maker pages fill gaps a listing leaves blank. They do not override a contradictory review. This is not a laboratory test. The weights below sum to 100.
Star rating
40%Stars are scaled from the listing as the star line divided by 5, then times 100. A high star line with a tiny count does not outrank a larger sample on its own.
Review confidence
20%Fifty-plus reviews score higher than a single star with no text. LiebeWH has 3 reviews, one with text. Cocoarm has 1 review and no text.
Listing usefulness
25%A steel thickness in millimetres, a printed air figure, and a head or radius claim. A missing thickness scores low. The LiebeWH 8 kg line is not treated as a bar figure. The 325B wattage line of 15 KW is ignored.
Review sentiment
15%Repeated stalls, a missing fitting, or a return against the stated thickness reduce the score. Maker pages fill blank listing fields, including Draper 9.8 cfm and the 325B NPTF inlet and load air.
Match thickness and air before you compare shelf price. An air nibbler punches sheet with a die. It is not a grinder, and it is not a cordless nibbler. The six prices below are amazon.co.uk shelves on 19 October 2026, from about £34.32 to £133.60. A printed millimetre, a printed cfm figure, and a BSP inlet unless the maker says NPT matter more than a tiny star line. Walfront and Cocoarm do not state a thickness. This is not a lab test.
An air nibbler is a pneumatic punch-and-die cutter for sheet metal. You use it for curves, internal holes, and profiled sheet when you already have a compressor and you do not want grinder sparks. On 19 October 2026 these six amazon.co.uk tools ran from about £34.32 to £133.60. Cordless nibblers and drill attachments are a different category. Buy the millimetre printed for that metal. Sealey SA28 and Draper 70835 state 1.5 mm steel. The 325B states 1.2 mm (18 gauge) and a 6.5 mm radius.
Free air delivery is the figure that feeds the tool, not tank litres and not pump displacement. Sealey states 4 cfm at 90 psi. Draper states 9.8 cfm. The 325B states 4 cfm average and 17 cfm at load. A bigger tank does not raise cfm. A 24 litre tank will not run every nibbler in this set.
Sealey and Draper state 1.5 mm steel. That line is not a stainless figure. LiebeWH puts stainless in the same 1 mm line as mild steel, which is not a separate stainless rating. Forcing a stall by raising pressure above the stated maximum is the same class of mistake. Sealey says do not exceed 90 psi.
UK workshop air is BSP. Draper and Sealey state 1/4 inch BSP. The 325B inlet is 1/4 inch NPTF, which will not seal properly in a BSP port. PCL and Euro couplers do not interchange. Some Draper buyers reported a connector that was not a standard 1/4 inch BSP fitting. Check the plug before the first cut.
Buy to the millimetre the maker prints for that metal. Sealey SA28 and Draper 70835 state 1.5 mm steel. Ingersoll Rand 325B states 1.2 mm, also written as 18 gauge. LiebeWH states 1 mm and names stainless in the same line. Walfront and Cocoarm do not state a capacity. A missing thickness scores low. Stainless stays a separate number unless the page prints one. Then match free air delivery at about 90 psi (6.2 bar), not tank litres.
UK workshop air is BSP. Draper and Sealey state 1/4 inch BSP. The 325B inlet is 1/4 inch NPTF, which will not seal properly in a BSP port. LiebeWH prints the inlet as 1/4 and does not say BSP. Draper and Ingersoll Rand both ask for a 10 mm (3/8 inch) hose. PCL and Euro couplers do not interchange. More than one Draper review says the connector was not a standard 1/4 inch BSP fitting. One Sealey review describes a BSP plug screwed in so tightly that the threads galled.
Three typical situations, each with a recommendation from this comparison.
You already have a compressor and you want a cold cut with a printed air figure. The Sealey SA28 states 4 cfm at 90 psi and steel up to 1.5 mm, at about £43.19, with 3.9 from 33 reviews. Check the inlet plug before the first cut. One buyer returned a unit that missed 1.5 mm mild steel at 90 psi.
You want a named 1.5 mm steel nibbler near £36 and the largest review count here. The Draper 70835 is about £35.56, with 4.2 from 57 reviews. The maker states 9.8 cfm, which the listing omits. More than one review says the connector was not a standard 1/4 inch BSP fitting.
You are cutting windows or vents in body skin, and you will stop at strengtheners, wiring, and pillars. The LiebeWH states 1 mm and a 1/4 inlet, at about £34.32. One UK review describes window holes in a Transit. There are only 3 reviews. Scrap-test first. A guess of 1 to 1.2 mm is not a specification for every van.
The top pick is the Sealey SA28, score 81, at about £43.19. It leads because the listing prints 90 psi and 4 cfm, the lowest printed air figure in this set, with a punch and die that rotates through 360 degrees. One reviewer cut 1.5 mm mild steel easily. Another returned a unit that missed that thickness at 90 psi, and the listing power-source line says AC. The best value is the Draper 70835, score 80, at about £35.56, with 4.2 from 57 reviews and a stated cut of up to 1.5 mm steel. The listing omits cfm. The maker states 9.8 cfm, and more than one review says the connector was not a standard 1/4 inch BSP fitting. Neither result is a lab win.
