Makita XGT 40V 4-½” / 5” Paddle Switch Angle Grinder

The Makita 40V max XGT® 4-1/2″ / 5” Paddle Switch Angle Grinder with Electric Brake (GAG03) 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 GAG03 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.

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.

There are 2 feature models of the GAG03 Paddle Switch Angle Grinder. The choice is with or without one battery and rapid charger. Both models come with standard accessories of grinding wheel, wheel guard, and side handle. Options for the Makita GAG03 are:

  1. GAG03Z: Tool only, with accessories
  2. GAG03M1: Tool, (1) 40V max XGT® Lithium-Ion 4.0Ah battery, rapid charger, tool bag, and accessories

The Makita 40V max XGT® 4-1/2" / 5” Paddle Switch Angle Grinder with Electric Brake (GAG03) 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 GAG03 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 GAG03 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.
