Description

Product Overview

The tapered thread mill is a solid carbide thread milling tool engineered for producing precision tapered (conical) threads such as NPT, NPTF, Rc/R (British Standard), and custom taper forms. Using CNC helical interpolation, one tool can produce the full tapered thread in a single operation, eliminating the need for dedicated taper taps and dies. Ideal for fittings, hydraulic connectors, and pneumatic port threading applications.

Technical Specifications

  • Thread forms: NPT, NPTF, Rc (BSPT), and custom taper profiles
  • Type: Solid carbide thread mill
  • Taper angle: As per standard (1:16 for NPT/Rc)
  • Flute count: Multi-flute for high productivity
  • Coating: Advanced PVD coating for extended life

Applications & Industries

  • NPT and NPTF threaded port machining (hydraulic and pneumatic)
  • BSPT (Rc) thread milling in fittings and manifolds
  • Precision tapered thread connectors for medical gas systems
  • Custom taper thread profiles for industrial and aerospace applications

Features & Benefits

  • CNC interpolation: one tool covers multiple diameters
  • Eliminates taper taps: no broken tap extraction problems
  • Reversible cutting direction: left and right-hand threads possible
  • Solid carbide: superior tool life vs. HSS taper taps
  • Consistent thread form throughout full depth of engagement
