Score: 72/100Rankings
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 VEVOR 1" SDS-Plus Rotary Hammer Drill is a 20V brushless cordless tool designed for light-to-medium duty concrete work, featuring 2.8 J of impact energy and 1200 RPM. While it offers high raw power specs at a budget-friendly price, the heavy weight and limited battery runtime are notable trade-offs. It is best suited for DIY homeowners and weekend warriors needing versatile cordless drilling for home renovations.
