M38x3 fine thread hand taps
Hand Tap M38x3 ISO 529/2 6H HSS is a precision tool designed for cutting M38 fine threads in structural steels, stainless steels and non-ferrous alloys. Thanks to accurate machining and matched working geometry, the M38x3 Hand Tapping Set makes it possible to obtain a stable thread profile with high surface cleanliness and predictable dimensional parameters, even in short-run cycles.
Technical parameters: nominal diameter thirty-eight millimeters; pitch three millimeters; outline sixty degrees according to ISO 68-1; hole tolerance class 6H according to ISO 965; right-hand design; straight chip grooves ensure uniform chip evacuation. Two-part design in accordance with ISO 529/2 - insertion tapping (I) and finishing tapping (II) - distributes torsional loads and maintains alignment. HSS ground version reduces micro-crushing and extends edge life. Recommended drill bit: thirty-five millimeter; use of emulsion or active oil increases surface quality and tool life.
- Smoothness of operation - sequential member design minimizes drag and improves cutting uniformity.
- Blade durability - high speed steel in a precision grind provides long-lasting sharpness and resistance to dulling.
- 6H grade fit - maintaining the effective dimension ensures a close fit to the 6g external thread.
- Dimensional stability - the machining process runs smoothly thanks to controlled chip evacuation and optimal outline geometry.
Meeting the requirements of ISO 529/2 (design), ISO 68-1 (metric profile) and ISO 965 (6H tolerance) guarantees full compatibility with inspection instruments and dimensional repeatability. In assembly and production applications, the reliability and stability of machining is ensured by Set Taps Manual M38x3, maintaining quality consistency in every stage of threading.
