DEWALT 20V MAX SDS Rotary Hammer Drill DCH273B — Cordless 1-inch Brushless with SHOCKS Vibration Control

The DEWALT 20V MAX SDS Rotary Hammer Drill (DCH273B) is a cordless, brushless 1-inch rotary hammer built for fast concrete drilling with three selectable modes and active vibration control.

Designed for tradespeople who need mobility without sacrificing power, the DCH273B combines a brushless motor and a German-engineered gearbox to deliver 2.1 joules of impact energy in a compact, lightweight package. It’s part of DEWALT’s PERFORM and PROTECT line, featuring the SHOCKS ACTIVE VIBRATION CONTROL System to reduce user fatigue and improve control during repetitive drilling tasks.

How does the DCH273B perform on concrete and masonry?

The DCH273B produces 2.1 joules of impact energy which enables efficient drilling in concrete, block, and other masonry materials. The SDS-style chuck provides secure bit retention for heavy-duty bits, and the durable mechanism is engineered for consistent impact delivery.

• 2.1 J impact energy for rapid drilling progress in concrete
• SDS system for fast bit changes and strong retention
• German-engineered mechanism for long-term reliability

What convenience do the three application modes add on job sites?

A rotating dial lets you switch quickly between Drill, Hammer Drill, and Chip modes so you can adapt the tool to multiple tasks without changing tools. This flexibility saves time when you move from drilling anchor holes to light chiseling or standard drilling operations.

• Drill mode for standard wood/metal drilling with appropriate bits
• Hammer Drill mode combines rotation and impact for masonry work
• Chip (chiseling) mode for light demolition and surface removal

How does vibration control help during extended use?

DEWALT’s SHOCKS ACTIVE VIBRATION CONTROL System reduces the vibration transmitted to the handles, improving comfort and control during prolonged use. Lower vibration can reduce operator fatigue and make it easier to maintain accurate placement and steady drilling speed.

• Active vibration system cushions impacts felt at the grip
• Improved comfort during repetitive drilling and anchoring work
• Designed to assist compliance when used with recommended accessories

What are the compatibility and safety notes I should know?

The DCH273B is sold as a bare tool (battery and charger not included), making it ideal if you already own DEWALT 20V MAX batteries. When paired with DEWALT’s DWH303DH On Board Extractor, this model becomes OSHA Table 1 compliant for certain dust-control applications.

• Bare tool only — compatible with DEWALT 20V MAX batteries
• Becomes OSHA Table 1 Compliant with DWH303DH On Board Extractor
• Brushless motor improves runtime and lowers maintenance

Who is this for? The DEWALT DCH273B fits electricians, mechanical contractors, and general tradespeople who need a portable SDS rotary hammer for anchor drilling, rod hanging, cable tray and strut mounting, clamp and rail installations, or light chiseling. It’s also a good choice for crews wanting DEWALT 20V ecosystem compatibility, reduced vibration for extended shifts, and a durable motor-and-gear system for frequent masonry work.
