Taper pipe thread
The TM559 series consists of professional-grade thread milling cutters specifically engineered for the precision machining of 60° American Standard Taper Pipe Threads (NPT) in accordance with the USAS B2.1:1968 standard. Manufactured from an ultra-fine grain carbide substrate, these cutters enable efficient and precise machining of 60° American threads (NPT series), making them an ideal choice for applications in mold making, aerospace, automotive manufacturing, and general machining. The series offers a range of high-performance coatings that ensure 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 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 USAS B2.1:1968 standard, meeting the threading requirements for American-standard tapered pipe fittings; the tapered thread is formed in a single pass, boosting machining efficiency by 40% compared to traditional taps.
Thread pitch accuracy is maintained within ±0.005mm, taper tolerance is ≤0.01mm, and surface finish reaches Ra ≤0.2μm, satisfying the stringent tolerance and sealing requirements for tapered pipe fittings.
Utilizes HRC68-grade ultra-fine grain carbide with 60% higher chip resistance, ensuring stable machining of pipe fitting materials such as steel and stainless steel.
The cutting edge radius is precisely controlled at 0.003mm, balancing sharpness with wear resistance to minimize edge chipping and ensure machining consistency.
Employs a vacuum ion plating process that increases coating adhesion by 40%, preventing coating delamination from compromising machining precision.
Direct application of cutting fluid reduces friction between the cutting edge and the workpiece, improving 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 a center hole, allowing for direct threading of blind holes; this reduces process steps and increases efficiency.
