How buyers search for taps

We align copy with the search pattern that converts best: [material grade] + [thread standard] + [size] + [tool type]. Examples buyers type before clicking ads:

  • M35 BSPT 1/2" spiral flute tap manufacturer
  • M42 UNC 5/16" plug + bottoming tap set supplier
  • M35 NPTF 3/4" pipe threading die India
  • M2 metric coarse M8 spiral point tap exporter
Use this when requesting: share your workpiece material, thread standard (e.g., BSPT, UNC, NPT), size, and whether you need spiral point, spiral flute or straight flute.

Applications & materials

  • Steels and alloy steels with cobalt-loaded taps for life and speed.
  • Stainless steel tapping with spiral flute for chip evacuation.
  • Cast iron and non-ferrous materials with straight flute sets.
  • BSP/NPT pipe threads for fittings, valves and hydraulic assemblies.
Typical pairing: HSS M35 spiral point for through holes; HSS M42 spiral flute for blind holes in SS; M2 straight flute for hand tapping in softer materials.

What we need to quote fast

  • Thread standard and size (e.g., M10x1.5, 1/2" BSPT, 3/4" NPTF, 5/8" UNC).
  • Tool style: spiral point, spiral flute, straight flute; plug/bottoming; dies or chasers.
  • Material grade preference (M2, M35, M42) and workpiece material.
  • Quantity and any coating needs (TiN/TiAlN).
