3" Grinder Overview
The 3" Grinder is engineered for industrial applications requiring compact power and durability. Its high-efficiency, large flow motor operates at high air pressure to deliver superior torque and extended tool life. The gearless design eliminates power loss and enhances performance, while the adjustable chrome guard ensures operator safety and ergonomic handling.
Designed for versatility, this pneumatic grinder can function as both a grinder and a cut-off tool using a unique adapter and spindle system. The simplified switch design allows easy on/off control, and side-exhaust air flow minimizes dust dispersion to maintain a cleaner work environment.
