 | The new tool is unique in two aspects, hence its name: CrazyDrill Twicenter.
Two integrated ducts supply the coolant directly to the exact spot where it is needed, right up to the drill’s cutting edge. The internal cooling is an advantage, always provided the machine used is equipped for it. No additional external cooling is needed. When drilling – and consequently when centering – in places difficult to access, bringing the coolant up to the cutting edge can be quite difficult. Only a precise internal coolant supply solves the problem. However the use of internal cooling is not always a must. It remains a first class center drill also for „conventional“ applications. A double point provides for more cutting stability. The tool with 60° or 90° chamfers are combined with a 130° tip angle, which apart from a better protection of the cutting edges also guarantees a perfect centering for the subsequent drilling operation. The third type with a 120° point angle gives stable performance due to the point angle. The diameters are matched to the existing CrazyDrill program. CrazyDrill Twicenter is available from stock in diameters from 0,3 mm to 6 mm.
