Small-diameter thread
The TC613 series of thread milling cutters is engineered to meet the rigorous demands of modern precision thread machining. Designed in accordance with the DIN 13 standard, these specialized tools enable the efficient and precise production of 60° metric threads (M-series), making them an ideal choice for mold making, aerospace, automotive, and general machining applications. Available with a range of high-performance coatings, the series delivers exceptional machining efficiency, superior surface finish, and consistent, long tool life across various materials with hardness levels below 28 HRC. They are particularly well-suited for machining micro-threads (M0.8–M3) in steel components for aerospace sensors and navigation equipment, where high reliability is essential.

Design details engineered for accuracy, tool life and process stability.
Shank diameters as small as 0.3 mm and cutting diameters ranging from M0.8 to M3; suitable for threading small-diameter holes in precision components, overcoming the inability of traditional tools to access narrow cavities.
Features HRC68-grade ultrafine-grained carbide with 60% higher resistance to edge chipping, enabling stable machining of materials such as steel, aluminum alloys, and titanium alloys.
Thread pitch accuracy is controlled within ±0.005 mm, and surface finish reaches Ra ≤ 0.2 μm, meeting the stringent tolerance requirements for precision components.
Designed for DIN 13 standard metric threads, it completes thread formation in a single pass, offering 45% higher machining efficiency compared to traditional taps.
Utilizing a vacuum ion plating process, coating adhesion is increased by 40%, preventing coating detachment that could compromise machining accuracy.
The direct action of the cutting fluid reduces friction between the cutting edge and the workpiece, improves the quality of the machined surface, and reduces cutter wear.
The cutting edge radius is precisely controlled at 0.003 mm, balancing sharpness and wear resistance, reducing edge chipping, and ensuring machining consistency.
Featuring an eccentric cutting design, it eliminates the need for pre-drilling a center hole and allows for the direct machining of blind-hole threads, thereby reducing process steps and increasing efficiency.
