Tungsten carbide drill is designed to strengthen the drill tip geometry to choose a design, which is different from the standard design geometry cone drill point geometry design. This is a tetrahedral shape of the drill tip, consists of a main and a secondary rear corner after corner composition, these two angles can better protect the tungsten carbide drill drill tip at the center. As a result of this tungsten carbide drills can generate a free cross-cutting edge, and can help tungsten carbide drill positioning. SD 216 overall structural design makes tungsten carbide drill before the formal process does not need to pre-drill a pilot hole.
