DeWalt DCH273B

Expert Review Analysis

The DeWalt DCH133B is a 20V MAX brushless cordless SDS-Plus D-handle rotary hammer designed for concrete drilling with 2.6 Joules of impact energy. It features a lightweight, compact design with three operational modes (drill, hammer drill, chip) to facilitate work in tight spaces and overhead applications. The tool is positioned as a versatile solution for light-to-medium duty structural tasks without the need for cords.

✓ Best for: Electricians, plumbers, and general contractors needing cordless mobility for light-to-medium concrete work. Specific use cases include rod hanging, structural connections, beam/column anchorage, steel stanchion mounting, and clip/bracket installation in tight or overhead spaces.✗ Not ideal for: Heavy chipping operations or drilling large-diameter holes exceeding 1 inch. Users requiring advanced vibration control or E-CLUTCH safety features should look to higher-end models like the DCH293B.

Pros

✓Delivers 2.6 Joules of impact energy for fast concrete drilling up to 1 inch
✓Brushless motor and German-engineered mechanism extend runtime and durability

Expert Opinion

Professional reviewers highlight the DCH133B's exceptional power-to-weight ratio, making it ideal for structural tasks such as rod hanging, beam anchorage, and clip installation. The 2.6J impact energy is noted for matching corded performance, while the lightweight design is praised for overhead work. However, experts note it lacks the advanced vibration control and safety features of higher-end models, positioning it best for light-to-medium duty applications rather than heavy industrial chipping.

What Users Say

Everyday users and professionals praise the tool for its compact access and reliability in drilling anchor holes in masonry. The cordless nature is frequently highlighted as a major benefit for mobility. Common complaints include noticeable vibration without SHOCKS technology and rapid battery drain during prolonged chipping. Users also note that the total weight, including the battery, can become tiring during extended use.

Common Complaints
