The Spline shank bits are carbide-tipped bits used for drilling holes in concrete, brick or block base material. The tip of the bit is made out of carbide. The Spline drive carbide-tipped bits are used in electro-pneumatic hammer drills. The Spline drive bits are attached to an electro-pneumatic hammer drill via a spline designed keyless chuck. Our Spline bits are American made from premium quality steel and carbide. The spline bits are available in diameters from 3/8" to 1-1/2" and lengths up to 36".
