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 Ryobi R18SDS-0 is a compact, cordless 18V SDS-Plus rotary hammer drill designed for light to medium-duty tasks such as drilling into masonry and light chiseling. Its lower impact energy and brushed motor are the main trade-offs compared to newer brushless models. It is best suited for DIY homeowners needing portability without cords for small hole drilling.
