CrazyDrill Twicenter from Mikron Tool is a unique tungsten carbide center drill with a double advantage. This drill with through-tool cooling is designed especially for the center drilling of difficult-to-machine materials. Customary centering drills wear out very quickly due to the strong heat buildup. Because of the through-tool cooling, CrazyDrill Twicenter keeps the machining temperature constantly low and lubricates the drill tip at the same time. The through-tool cooling shows its advantages even when drilling in difficult-to-access spots such as those with protruding edges. The cooling medium arrives at the right spot at all times. CrazyDrill Twicenter can also be used successfully with external cooling. The highest degree of position accuracy is guaranteed in each case. The extremely short chisel edge and the "double tip" – in chamfers of 60° or 90° with an additional tip angle of 130° – ensure stability and good chip flow. The adapted high-performance coating guarantees longer tool life. This centering drill, adapted for all types of drilling machines, machining centers and rotary transfer machines, is available from stock in diameters of 0.3 mm to 6 mm (.0118” to .236”) (center) or 1 mm to 10 mm (.0393” to .394”) (chamfer) and for chamfers of 60°, 90° or 120°. This center drill with through-tool cooling is also unique in two respects, hence its name: CrazyDrill Twicenter. Two cooling channels bring the lubricant where it is needed, directly to the drill tip. An additional external coolant supply is unnecessary. This is an advantage when centering in difficult-to-access spots, especially with materials with a poor thermal conductivity value such
