The 40V Max XGT® Brushless 1-1/8" Rotary Hammer is a high-performance cordless solution for heavy-duty concrete drilling and chipping. Delivering 2.7 ft-lb of impact energy, its Makita-built brushless motor features constant speed control to maintain power under load. The ergonomic D-handle design is ideal for overhead or hard-to-reach areas, while advanced AVT® and AFT® technologies reduce vibration and enhance user safety. Built for the job site, it includes XPT™ dust and water resistance and is AWS® compatible for wireless dust extraction.
Includes:
(1) Rotary Hammer Bare Tool
(1) Hammer Bit Grease
(1) CLOTH F/WIPING OIL
(1) Side Handle Assembly
- Anti-Vibration Technology (AVT®) is designed to reduce vibration for increased comfort
- Dust extraction capability with optional OSHA Table 1 compliant on-board HEPA Dust Extractor or stand-alone AWS® Extractor
- Auto-Start Wireless System (AWS®) utilizes Bluetooth® technology for wireless power-on/off communication (transmitter sold separately)
- Electric brake allows the tool to be repositioned faster for maximum productivity
- Torque limiting clutch engineered to prevent gear damage by automatically disengaging gears during a bind-up situation
- Variable speed trigger enables the user to match the speed to the application
- D-handle design is ideal for overhead, downward or hard-to-reach horizontal drilling/chipping applications
- Ergonomic soft-grip handle and large 2-finger trigger provide increased comfort on the job
- Built-in L.E.D. light with an independent on/off illuminates the work area
- Tethering loop/hanging hook helps secure the tool when working at heights or on a lift (sold separately)
- 3-mode operation for "Rotation Only", "Hammering with Rotation" or "Hammering Only" for multiple applications
- Multiple bit angles allow the bit to be set at different positions for increased comfort
- Extreme Protection Technology (XPT™) is engineered for improved dust and water resistance for operation in harsh conditions
- XGT® optimizes performance to provide up to 2X longer sustained power under heavy-load applications
- XGT® actively monitors and protects against overload, over-discharge and overheating
- Designed with a multi-layer contact interface for more constant power delivery to take on high-current demands
- Impact-resistant construction to secure the battery to the tool during high-demand applications (batteries not included)
- Dual-fan design circulates air through the battery to cool the battery and circuit board quickly for faster charging (charger not included)
- Digital display indicates battery charge level (-80%, +80%, 100%)
