Makita 40V Max XGT️ Rotary Hammer Kit 1-1/8In AVT with Dust Extractor - GRH01M1W
The Makita 40 Volt Max XGT cordless rotary hammer kit includes brushless 1-1/8 Inch AVT rotary hammer (GRH01Z), dust extractor attachment with HEPA filter cleaning mechanism (DX12), cloth towel (443122-7), 4.0 Amp-hour battery (BL4040), rapid optimum charger (DC40RA), side handle assembly (126882-3), grease (194683-7) and a tool bag. This cordless hammer tool is a great concrete solution designed for heavy-load applications. It delivers the power, speed and run-time for corded demands without the cord. The XGT technology delivers up to 135 of 3/8 Inch holes per charge when using one 40 Volt max 4.0 Amp-hour battery. Tool features constant speed control that automatically applies additional power under load for optimum performance. It also features Active Feedback-Sensing Technology (AFT) to electronically turn off the motor, if rotation of bit is suddenly forced to stop. The Anti-Vibration Technology (AVT) is an internal counterbalance that uses air pressure to move counterweight pistons in the opposite direction of the drive piston to actively reduce vibration. In addition, the vibration-absorbing back handle and side handle further reduce vibration. Tool with Extreme Protection Technology (XPT) system is engineered for improved dust, water resistance and added durability in harsh job site conditions.

Maintenance Tips
-
Clean tool & extractor after every use – wipe down the rotary hammer and dust extractor housing to remove concrete dust and debris that can clog vents and hinder performance.
-
Check HEPA filter regularly – clean or replace the dust extractor’s HEPA filter often to maintain effective dust capture and airflow.
-
Inspect SDS‑PLUS bits and accessories – examine bits for wear or damage and replace them promptly to ensure efficient drilling and reduce tool strain.
-
Grease bit shanks lightly – apply the included grease to bit shanks before drilling to reduce friction and prolong bit and chuck life.
-
Protect battery contacts – keep XGT battery terminals and tool contacts clean and dry for reliable power transfer and long battery life.
-
Store properly – store tool and dust extractor in a dry, cool place away from moisture and extreme heat to protect electronics and steel components.
-
Tighten handles & components – before each use, check that handles, side grips, and attachments are secure and free from play.
-
Follow Makita guidelines – refer to the owner’s manual for specific torque settings, cleaning instructions, and AWS/AFT functions to maintain warranty coverage.
