Overview
The RYOBI PCL445B operates on the RYOBI ONE+ 18-volt battery platform, making it an easy addition for anyone already invested in RYOBI's cordless ecosystem. Its 9000 RPM no-load speed is solid for standard angle grinder applications including metal prep, tile cutting, and weld grinding.
At 4 pounds, the PCL445B is a moderate-weight tool for a cordless grinder. Based on its specs and the depth of its review sample, it represents a well-rounded mid-tier option: not the lightest or fastest, but reliable and supported by a widely available battery system.
With 257 reviews at 4.5 stars and 400 units purchased last month, the PCL445B sits among the most actively bought cordless grinders in the $50 to $70 range. That demand level reflects genuine buyer confidence across a broad audience, from weekend DIYers to regular home-shop users.
