The Makita 40V MAX XGT 4-1/2 / 5 in. Angle Grinder Can Tackle Heavy Load Applications

The Makita GAG01M1 40V max XGT 4-1/2 / 5 in. Brushless Angle Grinder meets the capability of a corded grinder without the cord to deliver powerful cutting and grinding for the most demanding applications. Powered by a Makita brushless motor, the variable speeds range from 3,000 RPM up to 8,500 RPM for heavy-load applications that need increased power and speed. This angle grinder is ideal for grinding and cutting materials like tile, concrete, pipe, and conduit, and can cut 5/8 in. rebar up to 60% faster. The electric current limiter protects the motor from over-load when used in high-torque applications. An electric brake stops the wheel within 2 seconds, while Active Feedback-sensing Technology turns off the motor of the grinder if the wheel rotation is forced to stop. The Makita XGT angle grinder features a slide switch with lock-on for convenience and quick guard rotation for tool-less adjustments. Other features on this angle grinder include anti-restart protection to prevent motor start-up when the battery is inserted while the switch is locked on, and soft start provides smoother start-ups by suppressing start-up reactions.

The Makita XGT GAG01M1 features Makita Extreme Protection Technology for your angle grinder. Engineered for improved operation in harsh conditions, a protective seal is added inside the tool to repel water and dust away from key internal components. Additionally, wire mesh intake covers are engineered to prevent debris from entering the motor. With Auto-Start Wireless System capability, your tool can use Bluetooth technology for wireless power-on and power-off communication with a dust extractor. An AWS equipped dust extractor will automatically power on or off when your tool does. This function increases productivity and reduces noise on the jobsite. The XGT system of tools utilizes 40V max lithium-ion batteries. This system allows users to completely transition into a cordless jobsite because XGT is engineered to deliver high power and take on demanding applications. Equipped with advanced brushless motor engineering, intelligent digital communication, and superior durability, XGT cordless tools are designed to outpower, outsmart, and outlast the rest.
