Description

CrazyDrill Pilot, short drill, pilot drill and chamfer tool, is the perfect hole preparation for high-precision position accuracy in deep-hole drilling of lengths greater than 6 x d using twist drill types CrazyDrill Cool XL and CrazyDrill Cool. With the coated pilot drill or center drill CrazyDrill Pilot from Mikron Tool, centering and pilot drilling up to 2 x d are done in one single step. The follow-up drill is guided cylindrically in the pilot hole and this translates to a high degree of straightness for the hole. The precise adjustment of the tip angle from pilot drill to follow-up drill protects cutting edges and ensures reliability. CrazyDrill Pilot is available from stock in diameters of 0.4 mm to 6.35 mm (.016” to .250”, fractional inches available). Its special high-performance geometry ensures high machining speed and the optimal coating increases tool life, and all of this while maintaining constant drilling precision. In conventional centering with a 90° or 120° centering tool, the risk of cutting edge breakage and hole drifting is significant when a long follow-up drill is used. The follow-up drill, with a tip angle of 140°, first encounters the cutting edges at the 90° chamfer and is not accurately guided. CrazyDrill Pilot from Mikron Tool replaces classic centering with pilot drilling with a drilling depth of 2 x d. The follow-up drill is perfectly guided in the pilot hole, thus ensuring the straightness of the deep hole. Because of the sturdy design, the pilot drilling achieves a high degree of position accuracy. Moreover,
