Product Description

Engineered for the most demanding pipe threading applications, our Solid Carbide Full Profile NPT Thread Mill delivers superior performance and precision. Unlike single-point tools, this Full Profile cutter creates the entire thread shape (including the crest) simultaneously, ensuring perfect thread geometry and airtight seals essential for fluid and gas industries.


Why Choose TiAlCN Coating?

The TiAlCN (Titanium Aluminum Carbonitride) coating is a significant upgrade over standard coatings. It offers higher hardness and better thermal stability, making this tool the ideal choice for machining difficult-to-cut materials like Stainless Steel (304/316), Titanium Alloys, and Nickel-based Alloys where heat generation is a major challenge.


Optimized Geometry

Available in 3 or 4 flute configurations, this cutter balances chip evacuation with core strength. The helical flute design reduces cutting forces, minimizes vibration (chatter), and ensures a high-quality surface finish on the thread flanks.


Application Range:

  • General Steels: 45# Steel, Carbon Steel.

  • Mold Steels: P20, Pre-hardened steel.

  • Hard-to-Machine: Stainless Steel, Titanium Alloy, Nickel Alloy.

  • Abrasive Materials: Cast Iron.


 FAQ 

Q: What is the difference between "Full Profile" and "Single Point" thread mills?

A: A Full Profile cutter (like this one) cuts the complete thread shape, including the crest, in one pass. This ensures the thread depth and form are perfectly accurate according to NPT standards. A single point tool requires multiple passes to generate the form.

Q: Can this tool machine hardened mold steel like P20?

A: Yes, the solid carbide substrate combined with the TiAlCN coating makes it highly effective for machining pre-hardened mold steels like P20 and 45# steel.

Q: Is this suitable for CNC machining centers?

A: Absolutely. This tool is designed for CNC milling machines and requires helical interpolation programming to cut the tapered NPT thread.
