M14x1.25 fine thread hand taps
M14x1.25 ISO 529/3 6H HSSHand Taps are used for making M14 metric fine threads with a pitch of one and one-quarter millimeters in structural steels and metal alloys with strengths up to eight hundred mega pascals. A three-member system - ripper, intermediate, finisher - distributes torsional torque, ensuring smooth machining and maintaining a six H fit class.
Performance parameters: nominal diameter fourteen millimeters; pitch one and one-quarter millimeters; outline sixty degrees in accordance with ISO 68-1; bore tolerance class six H according to ISO 965; thread direction right; chip grooves straight to promote predictable chip evacuation. HSS ground version improves resistance to micro chipping and stabilizes edge sharpness. Work layout complies with ISO 529/3, and clear markings and organization of transitions are supported by the M14x1.25 Hand Tapping Set. Recommended drill bit for threads: twelve and seventy-five hundredths of a millimeter; using emulsion or active oil improves surface quality and extends blade life.
- Stable guidance - reduces torque fluctuations and the risk of chafing in through-holes and blind holes.
- Tool life - HSS high speed steel in a precision grind slows wear and keeps roughness low.
- Grade 6H accuracy - compliance with tolerance allows passing the pass/fail test.
- Process order - smooth operations and dimensional repeatability are supported by the M14x1.25 Hand Thread Set.
Meeting the requirements of ISO 529/3, ISO 68-1 and ISO 965 guarantees compliance with inspection apparatus, stable coil profile and predictable results in unit and short-run production.
