Overview
Running on an 18 volt battery, the RYOBI PCL445B grinder spins up to 9000 RPM and weighs about 4 pounds, light enough for one-handed use over a work session.
Cordless operation means no cord to manage on ladders or in tight spots, and the 4 pound weight keeps it maneuverable for extended use. Ryobi's PCL model numbering points to its 18 volt battery platform, though the listing does not confirm whether a battery or charger ships with it. Buyer demand looks healthy at 400 purchases in the past month.
- 18 volt battery powered
- 9000 RPM top speed
- About 4 pounds
Who it's for
Fits users already invested in Ryobi's 18 volt battery tools who want a light, cordless grinder for occasional cutting or grinding jobs. Less suited to continuous heavy grinding, where a corded tool holds power longer.
Pros and cons
- Cordless and light at about 4 pounds
- Fast 9000 RPM motor speed
- Strong recent demand
- Battery and charger inclusion not confirmed
- No listed disc size
Performance notes
At 9000 RPM the motor spins fast enough for typical grinding and cutting discs, while the 4 pound body keeps fatigue down during handheld work. Runtime and disc size are not listed, so actual job capacity depends on the battery and accessory used.
