Rank #7 in Best Orbital Sander 2026: 10 Models Ranked — and the Amp Figures That Don't Add Up
Bosch PEX 220 A 220 W Random Orbit Sander, 125 mm
Price and rating as shown on Amazon when we collected them. Both change.
The Bosch PEX 220 A is a corded random orbit sander with a 220 W motor, a 125 mm sanding pad and a microfilter dust box, sold in carton packaging for £51.99. It sits at number 7 in this guide, and its 4.5 out of 5 comes from 4,330 customer reviews. Bosch lists it at 1.29 kg with a maximum rotational speed of 24,000 RPM, a palm grip handle and three red wood sanding sheets in the box.
Its listing is also the cleanest example of the problem this guide is about. The spec table gives the motor 220 W and then gives the amperage capacity as 220 Amps. At the listed 240 volts, a 220 W motor draws about 0.92 A — so the amp figure is the wattage typed into the wrong box, roughly 240 times too large. Nothing else on the sheet contradicts the tool: the 125 mm disc, the 24,000 RPM and the 1.29 kg weight all read as a sander of this size. Everything on this page comes from the Amazon listing, not from testing we carried out ourselves.
How those 4,330 ratings break down

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Excellent machine - I have the smaller version, but it was struggling to go through some really stubborn factory lacquer and stain. This ate through 7 grades of a large dresser and a chest of drawers In a day. Very impressed with the speed and dust collection, especially considering how small, light and easy to use it is.”
Verified purchase“Useful and fits the hand easily, just the right size to fit into some awkward spaces, effective in use though if you're not used to using one you might find your hand gets pretty tired after long use.Dust box is useful but a dust mask is a good addition!”
