The Bosch GBH2-28L rotary hammer merits its place in the long line of legendary Bosch Bulldogs. It weighs only 6.9 pounds, yet delivers impact energy of 5,100 no-load bpm (blasts per minute) and 0-1,300 no-load rpm for drilling and chipping in masonry and concrete. The 1-1/8 inch diameter drilling capacity combines with three operation modes – drilling only, hammer drilling and chiseling – to ensure the Bosch GBH2-28L is ready to take on a variety of jobs, both big and small.
Bosch-exclusive KickBack Control is activated when there’s an unexpected bind-up situation, which the rotary hammer will immediately shut off to reduce dangerous tool kickback. KickBack Control helps to better control the rotary hammer and can reduce the risk of injury.
Additional user protection features includes vibration control, a counter-balance system that moves in the opposite director of the striker to optimize hammer action. And an overload clutch is included on all Bosch rotary hammers. In an overload situation the tool remains in operation, but the clutch disengages to prevent dangerous torque movement.
For U.S. users, this tool should be used in accordance to the OSHA silica regulations designed to limit silica dust exposure, as well as the owner’s manual.
