The Milwaukee M18 BOS125-0 is a cordless random orbital sander that runs on Milwaukee's 18V M18 batteries, and it takes third place in this guide. The listing quotes no amp figure at all — there is nothing here like the '270 Amps' the guide picks apart on other models — so the number to watch is the price: £89.59 buys the tool alone, because the product name ends in 'Bare Unit'.

What the listing does give you: 4.7 out of 5 from 1,136 ratings, with 85 of the 100 ratings in the breakdown at five stars and two at one star; 1.4 kg in the specification, against 1.41 kg in the bullet; and a 125 mm disc, since the model number says 125 while the diameter field says 5 Inches — 125 mm converts to about 4.9 inches, so those two figures agree once you allow for rounding. It sits 20th in Amazon's Random-orbit Sanders category, and the same page carries grit fields (80, medium, silicon carbide) plus an Included Components field that reads simply '1'. Everything on this page comes from the Amazon listing, not from any testing of our own.
