The Makita 40v Grinder GAG01Z XGT Brushless Cordless 4‑1/2” / 5″ Angle with Electric Brake, Tool Only delivers corded grinding performance without the cord. It’s powered by an 8,500 RPM brushless motor for increased power & speed. Ideal for grinding & cutting materials such as tile, concrete, pipe, conduit, & more. An electric current limiter helps protect from overload. Additional features include an electric brake that stops the wheel in 2 seconds or less, Active Feedback-sensing Technology (AFT®) that turns the motor off if the rotation of the wheel is stopped, & a convenient slide switch with lock-on. Quick guard rotation provides tool-less adjustments, & anti-restart protection is engineered to prevent motor start-up when the battery is inserted while the slide switch is locked on. A soft start to the Makita 40v Grinder GAG01Z suppresses start-up reaction & provides smooth start-ups. Wire mesh intake covers are engineered to prevent debris from entering the motor. XGT’s advanced features outpower, outsmart & outlast the rest.
