Hand Tap M1 metric
Hand Tap M1 ISO 529/3 6H HSS is designed for cutting M1×0.25 threads in low-carbon steels, aluminum and brass; as hand Tap metric M1 ISO 529/3 provides stable guidance and roughness control in through-holes and blind holes.
Profile angle 60 degrees; pitch 0.25 mm; nominal diameter 1.00 mm; recommended drill bit 0.75 mm. Three-piece set I/II/III (ripper, intermediate, finisher) with straight-ground grooves facilitates chipbreaking and alignment in micromechanics and precision electronics. HSS high-speed steel and 6H tolerance stabilize pitch diameter at hand feed; light lubrication with low-viscosity oil and 0.1-0.2 mm entry chamfer recommended.
- Guidance stability - elongated peel cone reduces the risk of beveling in thin-walled workpieces.
- Clean profile - a sequence of three passes distributes the load on the blades, improving surface quality and outline reproduction.
- Process control - Set Taps Manual M1 allows you to match the cutting stage to the material and depth, reducing the manual torque required.
- Dimensional Repeatability - Class 6H supports interchangeability with 6g fasteners and predictable assembly clearance.
Compatibility: ISO 529 (variant /3), ISO 68-1 metric thread profile, ISO 965-1 class 6H internal tolerances. Set Taps Manual allows work to be carried out in a staged manner, and the geometry and division of labor correspond to the practice of hand threading in micro-diameters.
Hand Tap M1 Metric promotes stable operations and repeatable M1×0.25 thread quality in workpieces with limited rigidity.
Frequently asked questions
1. Is it possible to thread by hand in a through hole without a peeler?
For M1, a full three-step sequence is recommended; omitting the peeler significantly increases cutting resistance and the risk of damaging the thread outline.
2.How to verify the conformity of the made M1 6H thread?
Use a suitable ring gauge or inspection screw in grade 6g; smooth screwing without excessive play confirms the 6H tolerance.
3.How to properly use a set of three M1 thread cutters?
Work sequentially: ripper → intermediate → finisher, guiding in the axis with the knob; after 1-2 turns, make a reversal to break the chip and stabilize the outline.
