DEWALT 20V MAX SDS Rotary Hammer Drill - Cordless Demolition Power

Our review of the DEWALT 20V MAX SDS Rotary Hammer Drill (DCH273B) with the DWH052 large hammer dust extraction finds it aimed squarely at tradespeople who need cordless impact power for concrete and demolition tasks. The bottom line: this combination delivers robust 2.1 Joules of impact energy in a compact, lightweight package with effective vibration control, and the extractor option makes it practical for dusty jobs when paired appropriately. It is a practical choice when portability, reduced vibration, and on-board dust control are priorities.

Key Features

• Brushless motor: The brushless motor offers longer runtime and improved durability compared with brushed equivalents, helping the tool stay productive on tough jobs.
• 2.1 Joules impact energy: Delivers corded-level drilling power for fast drilling in concrete and masonry without being tethered to a cord.
• Active Vibration Control: SHOCKS vibration control reduces user fatigue and improves comfort over extended drilling or hammering tasks.
• Lightweight design: The compact, lighter form factor makes it easier to use for overhead work like rod hanging, seismic attachments, and cable tray mounting.
• Dust extraction compatibility: The DWH052 large hammer extractor works with 1-1/8 in. pavement breakers and demolition hammers and features a 360 swivel and quick air lock connector for easy setup.
• OSHA Table 1 compliance path: When the 20V MAX rotary hammer is paired with the DWH303DH on-board extractor, it becomes compliant with OSHA Table 1 for reduced silica exposure.

Who It's For

This tool is best for professional contractors and serious DIYers who frequently drill into concrete, masonry, or other hard materials and need cordless convenience. Electricians, plumbers, and mechanical trades that perform overhead anchoring, seismic work, or cable tray installation will appreciate the compact weight and vibration control for repeated use.

Less appropriate for users who need extended runtime from a single battery pack without spare batteries, or hobbyists who rarely work with concrete and would be better served by a lower-cost hammer drill. The bare tool format also means buyers must already own or plan to buy compatible 20V MAX batteries and chargers.

Pros & Cons

Pros

• High build quality and power for cordless drilling in concrete and even reinforced material.
• Reduced vibration thanks to SHOCKS Active Vibration Control, increasing comfort and control.
• Compact, lightweight design that eases overhead and prolonged use.
• Dust extraction options that provide quick connection and 360 swivel for demolition work.

Cons

• Battery life receives mixed feedback, so expect to carry spare batteries for extended jobs.
• The tool is sold as a bare unit, so additional cost for batteries and a compatible extractor may be required.
