Product Details
Features & Benefits:
- Auto-Start Wireless System (AWS) Technology Features Wireless Dust Collection Technology!
- Hammer & Rotation / Hammer Only SDS-MAX Shank
- Variable Speed
- AWS (Auto-Start Wireless System) uses Bluetooth® technology to communicate between tool and vacuum and enable wireless control when used with Makita AWS cordless tools
- Advanced Anti-Vibration Technology (AVTTM) system incorporates vibration absorbing housing, active dynamic vibration absorber and damper spring to actively counteract the vibration of the tool for greatly reduced transmission to the operator
- eXtreme Protection Technology (XPT) offers maximum protection against dust, debris and liquids for optimal performance in extreme conditions
- Active Feedback sensing Technology (AFT) automatically shuts down the tool if there is a sudden drop in rotation speed (e.g. kick-back)
- Brushless DC motor with high power to weight and size ratio
- Brushless DC motor generates less heat buildup and is ideal for prolonged use in manufacturing / production applications
- 2 Operating Modes: Rotation / Rotation + Hammer
- Trigger-lock button prevents accidental start-up for increased safety
- Torque limiter stops bit rotation if bit jams for increased operator safety and tool protection
- Soft start feature gradually increases speed to eliminate start up shock
- No load motor suppression limits vibration and bit deflection when idling
- Variable speed dial allows operator to adjust speed based on materials or application
- Constant speed control maintains constant speed under heavy load
- One-touch SDS-MAX sliding chuck for easy bit installation and removal
- Dual LED job light with pre-glow and after-glow features illuminates work area
- Ergonomic soft rubber grip design for vibration absorption and comfortable operation
- Includes straight (drilling) and D-style (demolition) handles
