Rank #2 in Best Angle Grinder 2026: 10 Ranked, and the Wattage Claims That Fail
Bosch Professional GWS 9-115 S Angle Grinder, 900W, 115mm
Price and rating as shown on Amazon when we collected them. Both change.
The Bosch Professional GWS 9-115 S sits at number two in this guide, and it is a corded machine: the listing gives 900 watts, a 230 volt supply and a 1.66 kg item weight, at £78.54, rated 4.6 out of 5 from 203 ratings. That 900 W figure is the reason it places where it does — it is one of only three power figures across the whole guide that a domestic socket can actually deliver, while the cordless models on the list quote numbers no 18V battery can produce.
One row of its own spec table still does not hold together. The horsepower field reads '900 Watts': the same number and the same unit as the wattage field, filed under a different heading. Watts and horsepower are not the same unit, so that entry is the wattage copied across rather than a second measurement. Everything on this page — specifications, price, rating and buyer comments — comes from the Amazon listing and not from any test of our own.
How those 203 ratings break down
