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.

## Questions people ask

**Does the RYOBI R18AG-0 come with a battery?**

7,500 RPM. That figure appears in both the Item Highlight and the Maximum Rotational Speed field.

115 mm, as given in the Item Highlight alongside the 7,500rpm speed and metal cutting and grinding use.

4.7 out of 5 from 4,440 ratings, of which 82% are five-star, 14% four-star and 4% three-star.
