AOBEN Cordless Angle Grinder 4-1/2-Inch, 21V Battery Kit with Brushless Motor – Metal Cutting, Grinding, Polishing

Versatile cordless power for metalworking and more

Without a power cord to hold you back, you can work freely in workshops, on job sites, or anywhere your project takes shape, rain or shine.

Three adjustable speeds give you the right tempo for your task, whether you’re removing rust from a metal railing, trimming tile edges, or smoothing a rough surface. The 4-1/2 inch wheel size is a standard choice for a wide range of applications, and the tool’s compact, ergonomic design feels comfortable in hand for extended sessions.

• Three speeds up to 9500 RPM for metal cutting, grinding, descaling, and surface prep.

A smart operating chip may pause the tool to protect the motor and battery if overload or overheating is detected, allowing a moment to recover and continue when ready.
