From the Manufacturer
An industrial 11 amp motor delivering up to 2,650 BPM makes the HM1100C perfect for your smaller demolition jobs. Ideal for such applications as breaking and chiseling concrete, cutting asphalt, digging out hard packed gravel or frozen ground, and breaking stone. An electronic variable speed control dial can adjust the hammer speed (1,300-2,650 BPM) to match the material that is being broken. A specially designed dust proof chuck cap keeps intruding dust and debris from penetrating the interior of the hammer, and a unique varnish coating on the armature ensures that the motor is safe from foreign materials that may penetrate the exterior of the hammer.
