RC Thread Mill | Solid Carbide PT / BSPT Tapered Pipe Thread Milling Cutter

High-performance RC Thread Mill (also called PT, BSPT, or ISO 7/1 tapered pipe thread mill) made from solid carbide. Perfect for CNC machining of internal and external tapered threads, left & right-hand cutting. Multiple coatings available for steel, stainless steel, cast iron, titanium, and high-temperature alloys to maximize tool life and precision.

Product Overview

The RC Full-Form Thread Mill (also known as PT Thread Mill or BSPT Thread Mill) is a high-performance threading solution made from premium tungsten carbide (solid carbide). Designed for both CNC machining and precision manufacturing, this tool enables accurate threading of internal and external threads, including both left-hand and right-hand directions. With its full-profile cutting design, it delivers exceptional precision and efficiency in a single operation.

 

Key Features

  • Solid carbide (tungsten carbide) construction for superior hardness and stability.

  • Full-form thread profile for faster cycle times and high-accuracy results.

  • Cuts internal & external threads, supporting both left-hand and right-hand threading.

  • Compatible with a wide range of materials, from soft aluminum to superalloys.

  • Excellent surface finish, ensuring tight tolerances and reduced post-processing.

  • Long tool life with the right coating selection, even in difficult-to-machine alloys.

 

Material Compatibility & Coating Recommendations

Choosing the correct coating based on the material significantly improves cutting performance, chip evacuation, and tool longevity.

Applications

The RC Full-Form Thread Mill is widely used in:

  • Aerospace & Automotive components

  • Precision molds and dies

  • Hydraulic and pneumatic parts

  • General CNC machining of high-strength metals

 

Why Choose Our RC Full-Tooth Thread Mill?

Compared to single-tooth or triple-tooth thread mills, the RC full-tooth design allows for faster production cycles, greater consistency, and higher efficiency in threading operations. Whether you need to machine metric, imperial, or custom thread profiles, this tool ensures accuracy, durability, and versatility.

 

The RC Full-Form Tungsten Carbide Thread Mill is the ideal choice for manufacturers who require precision, efficiency, and flexibility in their threading operations. With coating options tailored to copper, steel, stainless steel, cast iron, titanium, and high-temperature alloys, it is a truly universal solution for modern CNC machining.
