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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cdiv class=\"attribute-values\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eOUTPOWER: Makita-built
