System 3 uses a special piston and port handpiece design that self oscillates using normal compressed air. This makes it simpler and less expensive than the other GRS pneumatic power tools. It is comfortable, lightweight and delivers controlled impact power allowing you to engrave metal, set stones, hammer, texture & stipple and carve wood. The System 3 handpiece stays cool in continuous use and utilizes the versatile GRS QC Tool System.
