Thread Mills
Precision thread mills for efficient and accurate internal and external threading in a wide range of materials and thread profiles.
About Thread Mills
MZG Tool Group's thread mills are precision-engineered cutting tools designed for creating internal and external threads through milling operations. Unlike traditional taps, thread mills offer greater flexibility, reduced risk of breakage, and the ability to produce threads in hardened materials.
Our thread mills feature advanced geometries and premium coatings to ensure optimal performance, extended tool life, and precise thread profiles. With thread milling, a single tool can produce multiple thread sizes, making it an economical and versatile threading solution.
Whether you're working with aluminum, steel, stainless steel, or exotic alloys, our comprehensive range of thread mills provides solutions for every threading challenge. From standard metric and UN threads to specialized profiles like NPT and BSPT, MZG thread mills deliver consistent, reliable results.

Thread Milling Process
Thread milling involves three coordinated movements: rotation of the tool, circular interpolation, and linear movement along the hole axis. This process creates threads with excellent surface finish and dimensional accuracy.
For optimal results, we recommend using MZG thread mills with high-quality tool holders and following our recommended cutting parameters for specific materials.
Thread Mill Types
- Single Profile: Creates one thread size per tool
- Multi-Profile: Creates multiple thread sizes with one tool
- Helical: For high-efficiency threading operations
- Form: For specialized thread profiles
Programming Considerations
Thread milling requires helical interpolation capability on your CNC machine. Our technical team can provide programming assistance and recommend optimal cutting parameters for your specific application.
