Cutting Tools: CrazyDrill Pilot

With the CrazyDrill Pilot, centering and drilling of a pilot hole up to 2 x Ø is carried out in one single operation, thereby guaranteeing tight tolerance for the follow-up drill process. A 90° chamfer is cut at the same time. Diameter ranges and tolerances are matched to the CrazyDrill program, making it suitable for perparing to drill deep holes over 6 x Ø in length. Its special high-performance geometry combined with optimum coating increases the service life many times over while maintaining constant drilling precision.

The CrazyDrill Pilot is available from stock, in diameters 0.4 – 6.0 mm ( .016 - .24) in increments of 0.05 mm ( .002) and of 0.1 mm for diameters above 4 mm, with a standard chamfering and centering length of 2 x Ø.
