Most of medical screws are machined on lathes, on the main spindle the thread and on the sub-spindle the hex lobular socket. That particular operation is usually slower and defines the cycle time. With every second of time saving the manufacturer wins: time and money. CrazyDrill Hexalobe and CrazyMill Hexalobe are solutions developed by Mikron Tool to achieve a clear improvement of efficiency when machining medical screws made from Titanium (mainly Titanium Grade 5 ELI / TiAl6V4 ELI / 3.7165), Stainless Steel (mainly 316LM / X2CrNiMo18-15-3 / 1.4441) or Cobalt Chrome (mainly CrCoMo28). Thanks to a perfect machining strategy and adapted parameters, the machining of hex lobular bone screws (better known as „TORX®“) is 50% faster, guaranteeing also a high degree of precision of the profile and achieving nearly burr-free results. The pre-hole drill CrazyDrill Hexalobe with tip angle of 140° and the flat drill CrazyDrill Hexalobe Flat with tip angle of 180° are available in the diameter range from T4 – T30 (0.9 to 3.8 mm, [.035“ - .150), or as customized combined drill. Micro endmill CrazyMill Hexalobe, is available in the diameter range from T4 – T30 (0.2 to 1.0 mm, [.008“ - .039), for milling depths of 3.5 x d and 5 x d and, depending on diameter, with 3 or 4 flutes.
