Makita 40V Max XGT️ (GRH07Z) 1-1/8 In. AVT Rotary Hammer (Bare Tool) - GRH07Z

Makita 40V Max XGT️ (GRH07Z) 1-1/8 In. AVT Rotary Hammer (Bare Tool) - GRH07Z

The Makita brushless cordless 1-1/8 Inch rotary hammer comes with a hammer bit grease, wiping cloth and a side handle. Hammer works well with SDS-plus bits and is ideal for heavy-duty applications. XGT technology produces up to 135 of 3/8 Inch holes per charge on a single battery. Brushless motor operates at an impact energy of 2.8 ft-lb and has a speed of 0 to 980 RPM and 0 to 5000 BPM. Constant speed mechanism automatically applies the power under load. Active feedback-sensing technology electronically shuts down the motor in case the rotation of the bits if stopped suddenly. Anti-vibration technology minimizes the vibration on the padded handle thus making it easier to use. Internal counterbalancing technology moves the counterweight positions in the opposite direction of the drive piston by utilizing the air pressure. Auto-Wireless technology makes use of Bluetooth connectivity for effortless wireless communication between the equipped tool and the dust extractor. Dust extractor automatically starts when the tool is running and stops immediately when the tool is stopped. This in turns enhances the productivity and minimizes the continuous noise at the jobsite. Torque-limiting clutch disengages the gears if the bits binds thus preventing any gear damage. Electric brake prevents sudden initiation and the integrated LED light brightens up the working surface. Retractable tool hook allows the user to store the tool when not in use. This tool is perfect for contractors, concrete contractors, road and bridge contractors, utility workers, pest control and maintenance operations. Overload protection safeguards the motor from burnout while using the tool in high-torque applications. User can choose three operational modes namely "rotation only", "hammering with rotation" and "hammering only" depending upon the applications. Extreme protection mechanism provides good resistance to dust and water in harsh weather conditions.

Maintenance Tips

• Remove the battery before cleaning, inspecting, or changing accessories.
• Clean dust, concrete debris, and buildup from the tool body, vents, and chuck area after each use.
• Inspect SDS bits regularly and replace worn, damaged, or cracked accessories for safe operation.
• Keep the chuck clean and properly lubricated to ensure smooth bit installation and removal.
• Check the side handle, mode selector, and adjustment controls for secure operation before use.
• Use dust extraction when drilling to reduce debris entering the motor and internal components.
• Wipe the tool with a soft, dry cloth; avoid gasoline, thinner, alcohol, or harsh solvents.
• Store the rotary hammer and 40V XGT battery in a clean, dry location away from moisture and extreme temperatures.
• Use genuine Makita accessories and replacement parts, and have servicing completed by an authorized Makita service center when needed.
