Makita 9557PB 4-1/2in Paddle Switch Angle Grinder with AC/DC Switch | 7.5A, 11,000 RPM

Powerful grinding meets thoughtful design

The Makita 9557PB 4-1/2 inch paddle-switch angle grinder is built for demanding professional tasks. With a robust 7.5 amp motor, it delivers rapid material removal and steady performance at up to 11,000 RPM, helping you tackle metal, masonry, and composite surfaces with confidence. The large paddle switch is easy to reach for quick control, while the compact 2-1/2 inch barrel grip keeps your hand close to the tool’s center of gravity for precise handling, even during extended sessions.

The tool employs labyrinth construction to shield the drive gear and bearings from dust and debris, promoting longer life in harsh workshop environments. An AC/DC switch adds versatility for different power sources on site, so you can adapt your workflow without swapping equipment. A spindle lock simplifies wheel changes, and the side handle can be mounted on either side to accommodate left- or right-handed users. At roughly 4.5 lbs, this grinder balances power with comfort, making it suitable for heavy grinding without excessive fatigue.
