The Makita 40 Volt Max XGT® 1-1/8 Inch brushless rotary hammer tool only with interchangeable chuck, is a perfect cordless concrete solution for heavy-load applications. It is precisely designed to deliver the more power, speed as well as run-time for corded applications, without the cord. 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.
