60° Metric Thread
The TM535 series consists of professional-grade thread mills specifically designed for machining 60° UNJ aerospace precision threads in accordance with the ANSI B1.1:74 standard. Featuring an ultra-fine grain carbide substrate, these tools enable efficient and precise machining of 60° Unified threads (UN series), making them an ideal choice for mold making, aerospace, automotive, and general machining applications. Available with a variety of high-performance coatings, the series ensures exceptional machining efficiency, superior surface finish, and consistent, long tool life across a wide range of materials with hardness levels up to 58 HRC. They are particularly well-suited for machining precision threads into steel components for aerospace sensors and navigation equipment, where high reliability is essential.

Design details engineered for accuracy, tool life and process stability.
Strictly adheres to the ANSI B1.1:74 standard to meet aerospace requirements for high-precision, high-fatigue-strength threaded connections; enables thread formation in a single pass, increasing machining efficiency by 45% compared to traditional taps.
Utilizes HRC65-grade ultra-fine grain carbide with 50% higher chip resistance, ensuring stable machining of common materials such as steel, aluminum alloys, and stainless steel.
Thread pitch accuracy is controlled within ±0.003mm, and surface finish reaches Ra ≤ 0.15μm, meeting the stringent tolerance requirements of aerospace components.
The cutting edge radius is precisely controlled at 0.005mm, balancing sharpness with wear resistance to minimize edge chipping and extend tool life.
Uses a vacuum ion plating process to increase coating adhesion by 40%, preventing coating delamination that could compromise machining precision.
Direct application of cutting fluid reduces friction between the cutting edge and the workpiece, improving machined surface quality and reducing tap wear.
Cutting edge radius precisely controlled at 0.003mm, balancing sharpness and wear resistance to minimize edge chipping and ensure machining consistency.
Features an eccentric cutting design that eliminates the need for pre-drilled center holes, allowing for direct machining of blind-hole threads; reduces process steps and boosts efficiency.
