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.
