Score: 92/100Rankings
The DeWalt DCH293B is a high-performance, pro-grade cordless rotary hammer that delivers corded-level power in a compact format. Its key strength lies in its 3.5 Joules of impact energy combined with advanced vibration control and safety features. It is best suited for professional contractors requiring heavy-duty drilling and chiseling capabilities.
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.

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 characterize the DeWalt DCH293B as a high-performance, pro-grade tool that successfully delivers corded-level power in a cordless format, highlighting its German-engineered mechanism and enhanced ergonomics.
Direct consumer reviews are not present, but inferred sentiment suggests users value the tool's power and runtime for heavy-duty tasks, though some note confusion regarding branding and voltage labeling.
