Product Description
Compact brushless rotary hammer with 1.4 Joules impact energy, SDS+ chuck, SHOCKS Active Vibration Control®, OSHA Table 1 compliance, and mode selector switch. Tool‑only version with side handle, depth rod, and belt hook included.
Overview
The Dewalt DCH172B ATOMIC 20V MAX* Rotary Hammer is engineered for demanding fastening and drilling tasks. Delivering 1.4 Joules of impact energy through a German‑engineered brushless mechanism, it ensures fast drilling in concrete with optimized runtime. Its compact and lightweight design makes it ideal for rod hanging, concrete forming, cable tray and strut mounting, clip and bracket mounting, and railing installation. Integrated with SHOCKS Active Vibration Control®, it reduces vibration felt at the handles compared to standard rotary hammers. When paired with the DWH200D dust shroud and DWH161D1 dust extractor, it becomes OSHA Table 1 compliant for dust control.
