Air orbital sander buying guide

Updated: 21 October 2026

You are looking at amazon.co.uk and the results mix a 150 mm bodyshop palm, a 125 mm furniture sander, a three-pad mini kit and, until you read the power line, a corded or 18 V sander that only shares the word orbital. This air orbital sander buying guide is the order behind the [air orbital sander comparison](/hub/sanders/air-orbital-sander): confirm the tool is pneumatic, match the pad to the panel, then the orbit to the scratch, then ask whether air use and the inlet thread are even stated. Shelf prices stay on that comparison. The Products Compared editorial team checked the amazon.co.uk listings on 19 October 2026. A qualifying purchase can earn a commission at no extra cost to you.

150 mm, 125 mm, or a mini

Pad diameter decides the job before brand does. A 150 mm pad covers a door skin, a bonnet or a flat panel. A 125 mm pad is easier on a chair rail, a drawer front or a curved repair where a larger pad rocks. A 25, 50 and 80 mm set is a spot tool: a headlamp edge, a mirror housing, a stone chip. A mini kit will not flat the next full panel, and a 150 mm pad bridges a tight corner. Hook-and-loop discs have to match the pad holes, or the dust path is blocked. HSE’s wood-dust sheet WD7 asks you to align those holes. Which listing is which size is on the best air orbital sander page.

Orbit, 2.5 mm or 5 mm

Orbit is how far the pad swings while it spins. 3M’s random orbital guide treats about 2.5 mm, often written 3/32 inch, as the finer scratch, and about 5 mm, or 3/16 inch, as general purpose. Ingersoll Rand’s UK table lists the 4152-HL at 2.5 mm and the 4151-HL at 5 mm. The amazon title states 2.5 mm only on the 4152-HL, so do not copy 5 mm onto the 4151-HL listing. On other palms a bullet may say 5 mm or 3/16 inch while the specification table says nothing. If the compressor cannot hold pressure, that orbit becomes a slow rub. That air question is the compressor for an air sander page.

Dust, inlet and the blank CFM line

A self-generated bag uses exhaust air to pull dust into a cloth sack. An exhaust siphon is the same idea with a hose claimed in the box. A vacuum-ready pad wants an external vacuum, and the tool does not collect dust by itself. UK workshop couplings are often 1/4 inch BSP. The Ingersoll Rand family on the manufacturer table is 1/4 inch NPT, and those threads do not seal if you force them. A UK review of a mini set here says the supplied tail may not match a male 1/4 inch BSP fitting. Draper’s page for the 65084 states about 3 cfm average at 90 psi and a 1/4 inch BSP inlet. Ingersoll Rand’s UK table states about 8 cfm average for the 4151-HL and 4152-HL. Several amazon rows print neither. A blank cell is unknown, not a small-compressor guarantee.

What to read on the listing

Read the power source before the star rating. The Proster prints Corded Electric on the specification line while the title, the 1/4 inch inlet and a 0.6–0.8 MPa bullet say pneumatic. Keep both lines. Do not buy it as a mains sander, and do not pretend the corded line is not there. A title can promise dozens of discs while a bullet promises a different count, which is what happens on one mini set here. The 4151-HL components line prints mechanical ratchets and pawls. The LithiCraft page prints weight as 1.12 kg and as 0.89 kg. Stars do not tell you the pad size. If you already own the tool and the question is oil, swirls or a pad that will not turn, that is how to use an air orbital sander.

Common questions

Should I buy 125 mm or 150 mm?
Buy 150 mm when the work is doors, bonnets and other broad panels, and 125 mm when the work is furniture and smaller repairs where a 150 mm pad would tip on an edge. A mini kit at 25 to 80 mm is a third decision, for spots, and it does not replace either palm.
Is a 5 mm orbit the one to get if I only buy one?
For mixed prep and finishing, 5 mm is the usual single orbit, and you control the scratch with grit. Choose 2.5 mm when the work is mostly a fine finish and you can accept a slower cut. 3M’s guide is the source of that split. Only trust the figure if the listing or the manufacturer table for that model actually states it. A blank orbit cell is not 5 mm by default.
When is a 25–80 mm kit the right tool?
It is the right tool for headlamps, small panels, motorcycle parts and corners a palm cannot enter. UK reviews of the mini sets in this comparison describe exactly that work. It is the wrong only tool if the next job is a full door. You will spend the afternoon with a pad that is too small to keep the surface flat, however many discs came in the box.
What does vacuum-ready mean compared with a dust bag?
Vacuum-ready means the pad is built to connect to an external vacuum, and dust collection is that vacuum’s job. A bag or an exhaust siphon uses the tool’s own exhaust to pull dust into a sack or hose. For wood, HSE still expects suitable extraction and, for most enclosed powered sanding, RPE of at least APF 20. A cloth bag is not a Class M certificate.
Why do some listings omit CFM?
Because the seller did not print it. Several amazon.co.uk rows in this set have no air-use line at all, while Draper’s manufacturer page states about 3 cfm average and Ingersoll Rand’s UK table states about 8 cfm average. A reviewer’s guess is not the plate. If the cell is blank, treat consumption as unknown and read the compressor page before you assume a small DIY tank will hold speed.
