The DeWALT DCH172B ATOMIC 20V MAX Cordless Brushless Ultra-Compact 5/8 in. SDS Plus Rotary Hammer (Bare Tool) is a high-performance rotary hammer built for jobs in tight spaces. Powered by a brushless motor and a durable German-engineered mechanism, it delivers 1.4 Joules of impact energy for fast drilling in concrete. Its lightweight, compact design makes it well suited for rod hanging, concrete forming, cable tray and strut mounting, clip and bracket mounting, and railing mounting. This is a bare tool - battery and charger are sold separately.

Key Features

• 1.4 Joules of impact energy - delivers fast drilling performance in concrete
• Lightweight, compact design - well suited for rod hanging, concrete forming, cable tray and strut mounting, clip and bracket mounting, and railing mounting
• Brushless motor and German-engineered mechanism - built for efficient performance and long-term runtime
• SHOCKS Active Vibration Control System - reduces vibration felt by the user at the handles compared to rotary hammers without this feature
• OSHA Table 1 compliant - when paired with the DWH200D shroud and DWH161D1 dust extractor (sold separately)
• Mode selector switch - allows quick switching between drill and hammer drill applications

Why This Product

• The compact, lightweight design makes this rotary hammer especially practical for repetitive overhead or awkward-angle work, such as hanging rod or mounting brackets, where a full-size rotary hammer would add unnecessary fatigue.
• SHOCKS Active Vibration Control reduces the vibration transmitted to the user's hands and arms during repeated concrete drilling, which matters directly for comfort and fatigue over a full day of use.
• Being OSHA Table 1 compliant when paired with the correct shroud and dust extractor gives contractors a straightforward path to compliant dust control on concrete drilling tasks without needing a separate system.
• As a bare tool, this rotary hammer is a cost-effective option for users who already have compatible 20V MAX batteries and chargers and don't need to purchase them again.
