Best air angle grinder
Updated: 22 October 2026
You have three amazon.co.uk listings open, all of them answering a search for an air angle grinder, and you want one name to come out on top. The heads are not the same job. One is a 125 mm grinder with a published air figure, one is a 100 mm head with a safety lever, and one is a 3 inch cut-off. A best air angle grinder, inside this snapshot, is the tool that matches the disc you will fit and the air you can supply. The [air angle grinder comparison](/hub/tools/air-angle-grinder) lists the three captures with their shelf prices. This page says who each one is for, and who should leave it on the shelf. Peter F. updated this on 22 October 2026 from those listings and public UK sources. We did not test the tools in a lab, and the review samples are small. A qualifying purchase can earn us a commission at no extra cost to you.

What best can mean in this set
A single winner is what most people want from a best page. These three listings do not give you one, because they drive different discs and the star lines sit on small samples. The ORAZIO shows 4.7 out of 5 from 11 ratings, the ABAC G-202 shows 3.9 from 20, and the NuoDunco shows 4.1 from 25. Several of those reviews are not from the UK. Sorting by the average would put the 100 mm head above the only 125 mm tool in the set, which is the wrong order if your drawer is already full of 125 mm wheels.
Trade 125 mm air grinders sit in another price band, and a US-style roundup that ranks Chicago Pneumatic or Ingersoll Rand in dollars is not a UK shop result. US PRO 8425 is on amazon.co.uk at about £37.09, with a stated 6 cfm, 90 psi, 1/4 inch BSP and five ratings. That listing shows what a fuller 125 mm page can print. It is context, not a fourth pick here. If your compressor, thread or guard need is not on the listing, the honest result is to wait. Those blanks are the point of the air angle grinder buying guide.
ABAC G-202 when you want a stated 125 mm head
The ABAC G-202 is listed at £62.99. It is the only capture stated for 125 mm sanding and cutting discs, at 10,000 rpm. The maker's shop page for part 2809913206 states a working band of 4-6.3 bar and 2.5 litres per second, which is 150 litres per minute or about 5.3 cfm. The amazon description also states 89.5 dB(A) and 4 m/s² for this model. Those noise and vibration figures come from the maker, not from a test we ran. The item weight is 1.44 kg. One UK review, dated 16 June 2025, calls it a decent air grinder and good value. That comment sits under the 3.9 average, beside reviews that mention air use a home compressor cannot sustain, a failure after a few uses, and a very loud tool.
It suits you if your wheels are already 125 mm and the compressor can hold about 150 litres per minute at up to 6.3 bar. It does not suit you if the compressor is a small household unit, or if you need a lock-off. The listing does not claim one, and one review says nothing stops an accidental start. The captured file does not name the inlet thread. Whether your compressor can hold that 5.3 cfm is the question on the air angle grinder compressor size page.
ORAZIO when you want a 100 mm head and a safety lever
The ORAZIO is listed at £27.99. The display shows a 100 mm, or 4 inch, disc, 11,000 rpm, a safety lever throttle, a side handle, and UK plus European 1/4 inch quick connectors. The item weight is 1.53 kg. The box lists one grinding disc, two hex wrenches and a packing box, not a carry case. Eleven ratings, including a UK text written before the tool was used, are too thin to treat 4.7 as a settled verdict. One review says suitable discs are hard to find, which matters if the bore does not match the wheels you already own.
It suits you if you want the smaller head, a stated safety lever, and connectors in the box, and you can buy discs marked at or above 11,000 rpm. A slower disc on that spindle is the wrong wheel, even when the arbor fits. It does not suit you if you need a stated guard, because the listing leaves the guard blank, or if you need a stated air figure, or if the work is 125 mm weld dressing. The connectors are not named as BSP or NPT. Compared with the ABAC, you pay less and you accept two blanks that the dearer listing at least tries to fill.
NuoDunco when the job is a 3 inch cut
The NuoDunco is listed at £29.99. It is a 3 inch mini air cut-off, not a 125 mm angle grinder. The display lists 20,000 rpm, a safety switch, an adjustable wheel guard and a 1/4 inch NPT fitting. The item weight is 905 g. The package line includes cut-off wheels, one 3 inch HSS saw blade and wrenches, though that wheel count conflicts with a line that says five wheels. One UK review says the tool is neither light nor quiet, which sits awkwardly against 905 g if you expected a featherweight cutter. Air consumption, noise and vibration are not stated. The 1,200 W field is a listing line on an air-powered tool, not a mains wattage.
It suits you if you are cutting sheet metal with 3 inch wheels and you can connect a 1/4 inch NPT fitting without forcing it onto a BSP-only airline. It does not suit you if the job is weld dressing on a 125 mm disc. A price close to the ORAZIO does not make the two tools interchangeable. The included HSS blade is what the box lists. It is not permission to fit every blade that will mount. If you needed a stated air figure, a BSP inlet, or a 125 mm head, wait for a listing that prints them.
Common questions
Which of the three is the best air angle grinder?
None of them is the best air angle grinder overall. The ABAC G-202 at £62.99 is the 125 mm head with a published air figure of about 5.3 cfm. The ORAZIO at £27.99 is a 100 mm head with a safety lever and no stated guard or air use. The NuoDunco at £29.99 is a 3 inch cut-off with a guard and a 1/4 inch NPT fitting. Pick the disc form that matches the job. If the listing omits a check you need, wait.
Is the dearest one the one to buy?
The ABAC is the dearest of the three at £62.99, against £27.99 and £29.99. The extra money buys a stated 125 mm head and a maker figure of 2.5 litres per second at up to 6.3 bar. It does not buy a named inlet thread or a claimed lock-off. If your wheels are 100 mm, or the job is a 3 inch cut, the dearer tool is the wrong head. Price ranks the shelf, not the job.
Is 4.7 from 11 ratings better evidence than 3.9 from 20?
No. The ORAZIO's 4.7 from 11 ratings is a higher average on a smaller sample than the ABAC's 3.9 from 20, and the NuoDunco sits at 4.1 from 25. Samples of that size shift quickly, and several reviews are not from the UK. One ORAZIO text was written before use. Read the complaints about noise, discs and early failures. Keep the purchase on disc form, inlet and stated air use.
Who is the ABAC G-202 for?
It is for a reader who already uses 125 mm discs and can supply about 150 litres per minute at up to 6.3 bar. The maker states 10,000 rpm, 89.5 dB(A) and 4 m/s² for this model. Skip it if the compressor is a small household unit, because one review says the air use is too high for that. Skip it if you need a lock-off, which the listing does not claim. The inlet thread is not named in the captured file.
When is the ORAZIO 100 mm enough?
It is enough when the work is a 100 mm, or 4 inch, disc, you want a stated safety lever and 1/4 inch connectors in the box, and you can source wheels marked at or above 11,000 rpm. At £27.99 that is a smaller spend than the ABAC. It is not enough when you need a stated guard, a stated air figure, or the 125 mm wheels you already own. Eleven ratings are too few to treat 4.7 as a settled verdict.
When is the NuoDunco the wrong tool?
It is the wrong tool when you wanted a 125 mm grinder or a BSP-only airline. The listing is a 3 inch cut-off at 20,000 rpm, with a safety switch, an adjustable guard and a 1/4 inch NPT fitting, at £29.99. NPT should not be forced onto BSP. It is also the wrong tool if you needed a stated air figure, because consumption is blank. The included HSS blade covers the blade in the box, not every blade that mounts.
Should you wait for a tool that states air use, noise and a guard?
Wait if those three lines decide whether you can run the tool. Only the ABAC, in this set, publishes air use, a noise figure and a cover. The ORAZIO states a safety lever and leaves the guard and the air figure blank. The NuoDunco states a guard and a safety switch and leaves air use, noise and vibration blank. A class chart is not a substitute for a blank on the listing you are about to pay for.
