Makita GAG03M1 40V Max XGT Brushless Lithium-Ion 4-1/2 in./5 in. Cordless Paddle Switch Angle Grinder Kit with Electric Brake (4 Ah) - GAG03M1

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.

Features:
  • POWER: 13 AMP Corded Power
  • PERFORMANCE: Makita-built brushless motor along with 40V max XGT® battery delivers up to 60% faster cutting speed
  • 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
