Score: 82/100Rankings
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.
The Bosch 11255VSR is a lightweight, corded SDS-plus rotary hammer offering robust 2.0 ft-lbs of impact energy and vibration control. Its main limitation is the corded design, which restricts mobility and requires access to a power outlet. It is best suited for professional contractors working in areas with reliable power access.

“Blasts through concrete fast-2.6J feels like corded power”
“Lightweight for overhead work; great runtime on 6Ah packs.”
“Vibration is noticeable without SHOCKS-hands tire after 30+ holes”
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.
