Makita 40V Max XGT️ Rotary Hammer Kit 1-1/8in AVT - GRH02M1
The Makita 40 Volt Max XGT brushless 1-1/8 Inch rotary hammer kit contain AVT rotary hammer with interchangeable chuck. Rotary hammer is a perfect cordless solution for taking on high-demand applications. Rotary hammer has Makita built brushless motor, which delivers a full 2.8 ft-lb of impact energy with 0 to 980 RPM and 0 to 5000 BPM. Tool featuring quick-change chuck, assists to switch from SDS-PLUS bits to 1/2 Inch keyless chuck in order to make use of straight shank bits. The XGT technology renders up to 135 of 3/8 Inch holes per charge when using a 40 Volt max XGT 4.0 Amp-hour battery. Constant speed control applies additional power automatically under load for superior performance. Rotary hammer has Extreme Protection Technology (XPT) to increase dust and water resistance, thereby assures increased durability in harsh job site conditions.

Maintenance Tips
-
Clean After Every Use: Wipe dust and debris from the tool housing, vents, and quick‑change chuck to prevent buildup that can affect performance and cooling.
-
Inspect & Grease Bits: Check SDS‑PLUS bits before use; clean and apply recommended hammer bit grease to the shank to ease insertion and reduce wear.
-
Check Fasteners & Handles: Tighten the side handle and any fasteners before operating for secure handling and accuracy.
-
Battery Best Practices: Use genuine Makita 40V Max XGT batteries, charge before full discharge, and store batteries in a cool, dry place to prolong life and maintain consistent power delivery.
-
Dust Extraction Care: If used with a HEPA dust extractor or AWS system (sold separately), empty and clean filters regularly to maintain strong suction and comply with dust control standards.
-
Cooling & Rest: After long or heavy drilling, let the tool cool before continuing to protect internal components.
