NPT Series Solid Carbide Thread Mill | 60° Taper Pipe Thread Cutter Manufacturer & Factory Price

The NPT Series Solid Carbide Thread Mills are designed for precise machining of American National Pipe Taper (NPT) threads with a 60° profile and 1:16 taper. Compliant with ANSI/ASME B1.20.1 standards, these tools are ideal for creating reliable, leak-tight tapered pipe threads used in hydraulic, pneumatic, oil, and gas systems across North America and global markets.

Made from ultrafine grain tungsten carbide, the NPT thread mills deliver superior hardness, wear resistance, and tool life. The sharp cutting geometry ensures stable performance, accurate thread forming, and a clean surface finish — all achieved through CNC helical interpolation without using traditional taps.

Key Features

• ANSI/ASME B1.20.1 Compliant – Precisely matches NPT 60° thread profile with 1:16 taper for accurate sealing threads.

• High-Performance Carbide Material – Made from micro-grain carbide for exceptional wear resistance, rigidity, and durability.

• Optimized Cutting Geometry – Sharp edges and high-helix flute design provide smooth chip evacuation and stable cutting.

• Flexible Thread Milling – One tool can produce various NPT or NPTF thread sizes by CNC program control.

• Coating Options – TiAlN / AlTiN / DLC coatings available for different work materials and extended tool life.

• Suitable for Multiple Materials – Excellent performance on stainless steel, carbon steel, alloy steel, aluminum, and copper.

• No Tap Breakage Risk – Ideal for blind or through holes; safer than conventional pipe taps.

• Efficient & Accurate – Ensures precise taper angle, thread pitch, and excellent surface finish for tight sealing.

Typical Applications

• Hydraulic and pneumatic fittings

• Oil and gas connectors

• Valves, pumps, and pressure vessels

• Pipe and fluid transfer systems

• Precision mechanical parts requiring tapered sealing threads
