60° Metric Thread
The TM531 series consists of professional-grade thread milling cutters specifically engineered for the precision machining of 60° American Standard UNF fine threads (per ANSI B1.1.74). Featuring an ultra-fine grain carbide substrate, these cutters enable efficient and precise machining of 60° American threads (UN series), making them an ideal choice for mold making, aerospace, automotive, and general machining applications. A range of high-performance coatings is available, ensuring exceptional machining efficiency, superior surface finish, and consistent, long tool life across various materials with hardness levels up to 58 HRC. They are particularly well-suited for machining precision threads on 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 the fine-thread connection requirements of precision equipment; achieves thread formation in a single pass, boosting machining efficiency by 40% compared to traditional taps.
Utilizes HRC65-grade ultra-fine grain carbide with 50% greater resistance to chipping, ensuring stable machining performance across common materials such as steel, aluminum alloys, and stainless steel.
Thread pitch accuracy is maintained within ±0.005mm, and surface finish reaches Ra ≤ 0.2μm, satisfying the stringent tolerance requirements of precision equipment.
The cutting edge radius is precisely controlled at 0.005mm, balancing sharpness with wear resistance to minimize edge chipping and extend tool life.
Vacuum ion plating technology increases coating adhesion by 40%, preventing coating delamination that could compromise machining accuracy.
Direct application of cutting fluid reduces friction between the cutting edge and the workpiece, improving machined surface quality and reducing tap wear.
The cutting edge radius is precisely controlled at 0.003mm, balancing sharpness with wear resistance to minimize edge chipping and ensure machining consistency.
Features an eccentric cutting design that eliminates the need for pre-drilling center holes, allowing for direct threading of blind holes and thereby reducing process steps and increasing efficiency.
