Makita HR166DSMJ Cordless Rotary Hammer Drill 18V SDS-Plus 2 Modes

The Makita HR166DSMJ is a compact and powerful cordless rotary hammer drill designed for professional drilling and light chiseling applications. Powered by an 18V LXT Lithium-Ion battery and featuring a brushless motor, this tool delivers efficient performance with reduced maintenance. The SDS-Plus chuck ensures quick and secure bit changes, while the two operating modes (rotary drilling and hammer drilling) provide versatility for various materials. With a maximum impact energy of 1.1 Joules and a no-load speed of 0-680 RPM, it offers precise control and effective drilling in concrete, steel, and wood. The built-in LED job light illuminates dark workspaces, and the variable speed control with forward/reverse rotation enhances usability. The torque limiter protects the user and tool from sudden bit binding. This kit includes two 4.0Ah batteries, a DC18RC charger, and a Makpac Type 1 case for convenient storage and transport.
