The Makita GRH08M1 40V Max XGT® Cordless Brushless 1-3/16' AVT® Rotary Hammer Kit is a game-changer for heavy-duty concrete work. It's a cordless solution that packs the power, speed, and long run-time you'd expect from corded tools, without the hassle of cords. Powered by a 40V Max lithium-ion battery and a Makita-built brushless motor, it's ready for any heavy-load task. With a fully charged 40V XGT® 4.0Ah battery, it can drill up to 135 of 3/8' holes. The variable speed dial and trigger let you adjust the speed according to the job. This powerful tool also offers advanced comfort and convenience features. The Active Feedback-Sensing Technology (AFT®) shuts off the motor if the bit's rotation suddenly stops, preventing potential damage. The Anti-Vibration Technology (AVT®) significantly reduces vibration. It's not just a padded handle; it's an internal counterbalance system that uses air pressure to move counterweight pistons against the drive piston. The vibration-absorbing back and side handles further enhance comfort. For tough job sites, the Extreme Protection Technology (XPT™) improves dust and water resistance. The GRH08M1 has dust extraction capabilities (sold separately) and meets OSHA Table 1 requirements with on-board HEPA Dust Extractor or stand-alone AWS® Extractor options. The Auto-Start Wireless System (AWS®) uses Bluetooth® technology to wirelessly control the power of the dust extractor (sold separately), turning it on and off when the tool starts and stops. This boosts productivity on a single charge and reduces noise. Constant speed control adds extra power under load for top performance. The torque limiting clutch disengages gears if the bit binds, protecting the gears. Other features include an electric brake for quick repositioning, a built-in L.E.D. light to illuminate the work area, an ergonomic soft-grip handle with a large 2-finger trigger for comfort, and a retractable hook to secure the tool when not in use. It has three operating modes - 'Rotation Only', 'Hammering with Rotation', and 'Hammering Only' - suitable for various applications. Ideal for mechanical/electrical/plumbing contractors, concrete contractors, road and bridge contractors, utility workers, pest control, and maintenance operations. It accepts SDS-PLUS bits. XGT is a comprehensive system of equipment, tools, batteries, and chargers using 40V Max lithium-ion batteries. It's engineered to deliver high power for high-demand tasks, enabling a complete transition to a cordless job site. With advanced brushless motor engineering, intelligent digital communication, and superior durability, XGT outperforms the competition.
Using the Makita GRH08M1 is easy. First, make sure the battery is fully charged. Insert the battery into the tool and you're ready to go. Choose the right SDS-PLUS bit for your task. You can adjust the speed using the variable speed dial and trigger according to the material and job. For example, use a slower speed for harder materials. When using the tool, hold it firmly with both hands. The vibration-absorbing handles will help reduce fatigue. If the bit gets stuck, the torque limiting clutch will disengage the gears to protect the tool. The Active Feedback-Sensing Technology (AFT®) will turn off the motor if the bit's rotation suddenly stops. This is a safety feature, so don't try to override it. When it comes to dust extraction, if you have the AWS® Transmitter and a compatible dust extractor, connect them via Bluetooth®. The dust extractor will automatically turn on and off with the tool. This not only keeps your work area clean but also improves air quality. After use, remove the battery from the tool. Clean the tool regularly with a dry cloth. If there's a lot of dust, you can use a brush to clean hard-to-reach areas. Store the tool in a dry place. Make sure to use only genuine Makita batteries and chargers. They're designed to work perfectly with the tool and come with a 3-year limited warranty. If you have any issues, contact Makita's customer service for assistance.
