- Cutting diameter: 5/16 in, optimized for strong, clean thread generation in a compact profile
- Shank size and compatibility: 1/2 in shank with MT11 compatibility for wide compatibility with standard toolholders
- Thread depth capability: Up to 2x the thread diameter, enabling deeper threads in a single setup when possible
- Flute configuration: 3–4 flutes designed to balance rigidity, chip evacuation, and threading stability
- Material and construction: Hard-type carbide substrate built to cut hardened materials and high-performance alloys with precision
This multifunction thread mill is ideal for production runs and prototype work where you need one tool that can handle a variety of thread forms and tough materials. Expect strong edge retention, dependable thread quality, and consistent results when threading components in automotive, aerospace, and mold-making applications. The combination of carbide durability, flexible thread-profile support, and a robust flute design helps you reduce tool changes, minimize downtime, and maintain tight tolerances across challenging materials and geometries.
