Score: 85/100
DeWalt DCH133B 1 inch
Score: 82/100Rankings
The DEWALT DCH273B is a compact, cordless rotary hammer featuring SHOCKS vibration control and OSHA compliance, making it ideal for professional use in tight spaces. While its 2.1 Joules of impact energy is modest, the vibration reduction and safety features offset this for many users. It is best suited for electricians and plumbers who prioritize comfort and compliance over raw power.
The DEWALT DCH133B is a brushless, lightweight cordless rotary hammer delivering 2.6 Joules of impact energy, ideal for structural connections and anchor installations. While it lacks advanced vibration control and safety features, its compact design and high power-to-weight ratio make it a versatile choice for medium-duty work. It is best suited for professionals needing portable power for concrete drilling in tight or overhead spaces.

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.
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.
Professional reviewers and editors highlight the DCH133B's impressive power-to-weight ratio, noting that its 2.6 Joules of impact energy makes it ideal for structural connections, rod hanging, and mechanical anchors. Editors praise the German-engineered mechanism for its reliability and the brushless motor for extending runtime. While it is commended for its compact design and ability to perform tasks quickly, some analogs note that it trades advanced safety and vibration control features for affordability and portability.
Everyday users frequently praise the tool for its ability to blast through concrete with speed comparable to corded models, making it highly effective for anchors and brackets. The lightweight design is a major plus for overhead work, though users note that runtime is heavily dependent on using 6Ah or larger batteries. Recurring complaints focus on the lack of vibration control, which leads to hand fatigue after extended use, and occasional slipping of the side handle in wet conditions.
