Overview

RYOBI's PSBDG01B spins up to 22000 RPM on the brand's 18V battery platform, a speed that points to compact detail grinding rather than heavy stock removal.

22000 RPM is well above what a typical angle grinder runs, and lines up instead with a compact die grinder built for deburring and shaping small parts. Running on RYOBI's 18V system, it fits into that battery family rather than needing its own charger and pack.

Who it's for

Suits RYOBI 18V battery owners who want a high speed, compact tool for deburring metal edges or shaping small pieces. Not the right choice for anyone needing a full-size angle grinder for cutting or grinding down larger material.
