Score: 88/100Rankings
The Bosch GBH2-28L is a lightweight, corded SDS-plus rotary hammer designed for drilling, hammer drilling, and chiseling in concrete and masonry. Its primary limitation is the mandatory 5-hour break-in period required for optimal power. It is best suited for trade professionals needing a lightweight, high-power tool for daily concrete and masonry work.
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 praise the Bosch GBH2-28L as a 'legendary Bulldog' built for tough jobsites, highlighting its impressive 5,100 BPM and 1,300 RPM in a lightweight 6.9 lb package. Experts emphasize its exclusive features like KickBack Control and vibration control.
Everyday users commonly praise the tool's robust performance in heavy-duty applications, noting the comfortable D-handle and low vibration levels. However, recurring complaints focus on the mandatory 5-hour break-in period required for optimal power.
