The Bosch 11232EVS electronic variable-speed spline rotary hammer runs at 180 to 360 rpm and 1,600 to 3,200 beats per minute. The tool’s electronic feedback circuitry provides soft-start and maintains a constant speed under load. The service reminder light indicates when the tool needs servicing eight hours in advance of tool shutdown, while the improved electro-pneumatic impact system minimizes vibration and ensures a constant, more powerful impact. The hammer’s maximum capacity is 1-1/2 inches for spiral bits; 2-1/2 inches for thru hole bits; and 3-1/2 inches for core bits. Includes depth gauge, dust shield, 360-degree auxiliary handle, and metal carrying case.
