MAKITA DHR171 18V LXT BL Brushless Cordless 17 mm (11/16″) Rotary Hammer SDS-PLUS Bits

MAKITA DHR171 18V LXT BL Brushless Cordless 17 mm (11/16″) Rotary Hammer SDS-PLUS Bits,

• BL Motor Delivers 0-680 RPM, 0-4,800 BPM and 1.2 Joules of Impact Energy for Faster Drilling
• Compact and lightweight for reduced operator fatigue
• BL-motor-with high power to weight and size ratio
• BL-motor-is electronically controlled to optimize battery energy use for up to 50% longer run time per charge
• BL-motor-eliminates carbon brushes, enabling the BL motor to run cooler and more efficiently for longer life
• BL-motor-efficiently uses energy to match torque and RPM to the changing demands of the application
• Dust cup connectable to Makita vacuum cleaner (country-specific): Suitable for upward operation: For cleaner work environment
• Built-in LED light with afterglow function illuminates the work area
• 2-Mode operation for “Rotation Only” or “Hammering with Rotation” for multiple applications
• Side grip with elastomer soft grip
• One touch sliding chuck enables quick and easy bit changes
• Variable speed trigger allows operator to adjust speed based on materials or application
• Constant speed control automatically applies additional power to the motor to maintain speed under load
• Depth gauge for increased drilling consistency
• Conveniently located push button for rotation reverse
• Electric brake for maximum productivity and increased operator safety
• Battery protection circuit protects against overloading, over-discharging and over-heating. Optional hook is convenient for temporarily hanging the tool
