  • CONTROL : AFT® turns the motor off if rotation of the wheel is suddenly forced to stop
  • PRODUCTIVITY : Electric brake stops the grinding or cut-off wheel in 2 seconds or less for maximum productivity
  • INCLUDES : (1) 40V max XGT® Lithium-Ion 4.0Ah battery, charger, grinding wheel, wheel guard, side handle and bag

The 40V max XGT® Brushless Cordless 4-1/2" / 5” Paddle Switch Angle Grinder Kit with Electric Brake (GAG03M1) delivers corded grinding performance without the cord for the most demanding applications. It's powered by a Makita-built brushless motor which delivers 8,500 RPM for heavy-load applications and increased power and speed. The GAG03M1 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.

A large paddle switch provides power-start press points at multiple grip positions. A quick guard rotation provides tool-less adjustments for increased productivity. Anti-restart protection is engineered to prevent motor start-up when the battery is inserted while the switch is locked on. A soft start suppresses start-up reaction and provides smooth start-ups.

Wire mesh intake covers are engineered to prevent debris from entering the motor. The GAG03M1 is also equipped with Makita's Extreme Protection Technology (XPT™), a series of protective seals inside the tool. XPT is designed to improve a tool’s operation in harsh conditions by channeling water and dust from key internal components. Reinforced metal gear housing provides additional durability on the job site.

XGT is a system of equipment, tools, batteries and chargers utilizing 40v max lithium-ion batteries. XGT is engineered to deliver high power to take on high-demand applications, allowing users to completely transition to a cordless job site. XGT is equipped with advanced brushless motor engineering, intelligent digital communication, and superior durability features to outpower, outsmart and outlast the rest.
