Rank #3 in Best Angle Grinder 2026: 10 Ranked, and the Wattage Claims That Fail
RYOBI 18V ONE+ Angle Grinder, 115mm, Body Only
Price and rating as shown on Amazon when we collected them. Both change.
The RYOBI R18AG-0 is a 115mm cordless angle grinder that runs on the 18V ONE+ battery range, and it takes third place in this guide. It is sold as a bare unit at £67.45 and carries a 4.7 rating from 4,440 ratings, with 82% of those ratings at five stars.
The number to read carefully here is the power figure: the Horsepower field says 4 Horsepower while the Power source field says Battery Powered at 18.0 V. That is the same mismatch flagged across the cordless models in this guide, and the listing quotes no wattage for this one at all. Where it is straight is the battery: the product name says 'Battery & Charger Excluded' and the first bullet says 'Bare unit - no batteries supplied', which is the same story in two places. Everything on this page comes from the Amazon listing, not from any testing we have carried out.
How those 4,440 ratings break down
An average hides its own shape. This is the spread behind the 4.7 stars.

Questions people ask
