55° Tapered Locking Thread
The MT730 series is a professional-grade thread end mill specifically developed for precision machining of 55° imperial taper threads on orthopedic implants/locking plates. Designed for the characteristics of biomedical materials such as titanium alloys (Ti-6Al-4V, etc.) and cobalt-chromium-molybdenum alloys (CoCrMo), it employs an ultra-fine grain cemented carbide substrate and a medical-grade coating solution (TiAlN/DLC) to ensure excellent biocompatibility while achieving medical-grade standards of thread machining accuracy ±0.005mm and surface roughness Ra≤0.2μm. It provides an efficient, stable, and safe precision thread machining solution for orthopedic implants such as bone plates, interbody fusion devices, and joint stems.

Design details engineered for accuracy, tool life and process stability.
Utilizes HRC68 grade ultra-fine grain cemented carbide, improving chipping resistance by 60% and enabling stable machining of difficult-to-machine biomaterials such as titanium alloys and cobalt-chromium-molybdenum alloys.
Adapted to the standard taper thread design for orthopedic implants, taper thread forming can be completed in a single pass, increasing machining efficiency by 50% compared to traditional taps.
Thread pitch accuracy is controlled within ±0.005mm, and surface finish reaches Ra≤0.2μm, meeting the stringent tolerance requirements of orthopedic implants.
The cutting edge radius is precisely controlled within 0.003mm, balancing sharpness and wear resistance, reducing edge chipping, and ensuring consistent machining.
Utilizing a vacuum ion plating process, coating adhesion is improved by 40%, preventing coating peeling and contamination of the implant surface.
Hardness HV3400, coefficient of friction 0.4, suitable for machining common implant materials such as titanium alloys and stainless steel.
The direct action of cutting fluid reduces friction between the cutting edge and the workpiece, improving surface quality and reducing tap wear.
