The Ulitmax has 6 cutting edges which reduces binding and offers increased concentricity of the hole. The flex exerted in the lower section of a drill bit is the most likley destructive factor. The progessive core of the spiral adds material and increases the rigidity in this area which is subjected to extreme pressure.
