The Bosch Rotary Hammer 11228VSR is a power tool intended for use in heavy duty drilling and chiseling in concrete and masonry. It was released by Bosch in 2019. The device is equipped with a 7.5 amp motor that generates 2.1 ft-lbs of impact energy. Other specifications include a chuck type of SDS-Plus, an impact rate of 0 - 4800 BPM and a no load speed of 0 - 900 RPM. The maximum drilling capacity of the tool is 1-1/8" in concrete, with a maximum core bit diameter of 4". The Rotary Hammer also features an anti-vibration technology, a variable speed trigger and a lock-on button.

The Bosch Rotary Hammer 11228VSR is constructed with a cast metal gearbox and an all-metal transmission, designed to endure heavy usage typically associated with concrete drilling and chiseling. The anti-vibration technology reduces vibration by up to 50% compared to prior models. The tool is intended for concrete drilling, chiseling and fastening applications, with the hammer mechanism engaging when drilling into concrete or masonry. This delivers a high percussion power to drill holes up to 1-1/8" diameter. An all-metal transmission and hardened steel hammer mechanism allows it to withstand frequent high torque applications. The variable speed trigger allows users to match the speed to the application.
