Bosch Electric Hammer Drill Model #11230EVS

The Bosch Model #11230EVS is a powerful, lightweight electric hammer drill that has several features that make it ideal for drilling in both soft and hard stone.  Both the blows per minute and the rotating speed can be varied according to the type of stone and the desired hole size.  Once the right impact rate & speed are selected special electronic circuitry keeps them constant regardless of the load.  Rotation can also be stopped completely, so that the 11230EVS can be used as a chipping hammer.  Perfect for hole sizes from 1/2" to 1" in granite and up to 1-1/2" in softer stones, the 11230EVS can also used with core drills.  Includes carrying case.
