Makita DHR171RTJ 18v LXT SDS+ Plus Brushless Rotary Hammer 17mm inc 2x 5.0Ah Batts

Makita DHR171RTJ 18v LXT SDS+ Plus Brushless Rotary Hammer 17mm inc 2x BL1850B 5.0Ah Batteries, DC18RC Charger & Makpac Type 3 Carry Case

Makita has created a new class in cordless with 18V LXT new compact tools. The Brushless DHR171 17mm SDS Plus Rotary Hammer is ideal for working in tight spaces and for overhead conditions.

The DHR171 has an efficient Makita Brushless Motor for up to 50% longer run time, increased power and speed, and longer tool life. It has 2-mode operation for “rotation only” or “hammering with rotation”, with 0-680 RPM, 0-4,800 IPM and 1.2 Joules of impact energy for fast and efficient drilling. The compact size and lower weight mean reduced fatigue for operators, especially for overhead applications.

Additional features include a vibration-absorbing handle that moves independently of the motor and hammer mechanism for increased operator comfort, as well as a variable speed trigger, built-in L.E.D. lights, and one-touch sliding chuck for easy bit changes.

This DHR171RTJ kit comes complete with 2x BL1850B 5.0Ah lithium-ion batteries and an DC18RC charger, all packed in a Makpac type 3 carry case with inlay tray.

FEATURES
