The 1-3/16” Rotary Hammer (HR3001CK) is engineered for performance and power. It has a 7.5 AMP motor that delivers 2.6 ft.lbs. of impact energy to handle the most demanding applications. The 3-mode operation offers “rotation only”, “hammering with rotation” or “hammering only” for multiple applications. Modes can be easily changed with a recessed hammer-function selector, which is located below the gear housing for improved durability.
