60°Taper Pipe Thread Tap With Cylinder Shank with Key‑Slot (TiN coated)
Product Overview
60° Taper Pipe Thread Tap with Cylindrical Key‑Slot Shank features titanium nitride (TiN) surface coating. It complies with GB/T12176‑2002 and ASME B1.20.1‑1983 standards. The key‑slot cylindrical shank delivers stable torque transmission for special machine tool holders. Designed for tapping internal threads on high‑temperature, high‑pressure pipeline connectors with thread‑sealing requirements.
Compliance Standards
- GB/T12176‑2002
- ASME B1.20.1‑1983
Product Features
- TiN Titanium‑Nitride Coating: Golden surface treatment enhances hardness and wear resistance, extends tool service life for heavy‑duty high‑temperature & high‑pressure machining.
- Cylindrical shank with key‑slot: Key‑slot structure transmits torque reliably, prevents shank slipping under high‑torque tapping, compatible with dedicated machine tool holders.
- 60° thread angle,1:16 taper ratio: Fully meets American NPT pipe‑thread specifications, provides excellent self‑sealing performance for pipeline joints.
- Multi‑flute options: 3‑flute,4‑flute,6‑flute designs for smooth chip evacuation, stable performance in mass‑production of high‑pressure pipe fittings.
- Complete size range: Covers NPT sizes from 1/8‑27NPT to 2‑11½NPT, meets various high‑temp & high‑pressure connector machining demands.
