The small drill with through-tool cooling CrazyDrill Cool from Mikron Tool also resolves drilling problems in difficult-to-machine materials. The combined use of a pilot drill (solid carbide drill bits CrazyDrill Pilot or CrazyDrill Crosspilot) and the small drill with through-tool cooling CrazyDrill Cool allows drilling depths of up to 15 x d (other standard lengths: 6 x d and 10 x d) and this in drill size diameter ranges of 0.75 mm to 6 mm (.030” - .236”, coated version in fractional inches available). A shaft-integrated power chamber (up to a drill diameter of 2.95 mm / .116”) allows a more efficient coolant supply directly to the drill tip results in higher drilling speeds and tool life. A double advantage! In addition, the drilling concept of the CrazyDrill Cool is an alternative to the long and costly deep-hole drilling methods using single-lip drills (gundrill). CrazyDrill Cool is used everywhere where long drills are needed to create deep and accurate holes. The drilling concept from Mikron Tool is especially designed for deep holes and is based on a two-stage principle. Centering and pilot drilling is carried out in one step with two types of drill bits: CrazyDrill Pilot or CrazyDrill Crosspilot. CrazyDrill Cool then reaches the maximum drilling depth in one or more pecks (depending on material). By means of fine-tuned tolerances the long drill is not only guided very well in a cylindrical bore but also produces a hole with the best quality. On inclined surfaces the combination with CrazyDrill Crosspilot works best allowing center drilling with an inclination angle of up to 60°.
