Ohio Power Tool carries air rotary drills from Chicago Pneumatic.  These versatile tools are both a drill and a chipping hammer.  A push of the rotation release button easily and quickly converts the tool to a hammer.  Rotary drills are designed for a wide variety of construction and maintenance applications such as driving or setting masonry anchors and drilling holes in concrete, bricks or rock.  These tools can be used for chipping, scarifying, scaling and cleaning welds.
