Description

The 40V max XGT® Brushless Cordless 4-1/2" / 5” Angle Grinder with Electric Brake and AWS® (GAG04Z, tool only) delivers corded grinding performance without the cord for the most demanding applications. It's powered by a Makita-built brushless motor which delivers variable 3,000-8,500 RPM for heavy-load applications and increased power and speed. The GAG04Z offers up to 60% faster cutting speed when cutting #5 (5/8”) rebar. It is ideal for grinding and cutting a wide range of materials including tile, concrete, pipe, conduit, and more.

An electric current limiter helps protect the motor from overload in high-torque applications. Additional features include an electric brake that stops the grinding or cut-off wheel in 2 seconds or less and Active Feedback-sensing Technology (AFT®) that turns the motor off if rotation of the wheel is forced to a stop.
