Thread Milling Cutters
Precision thread milling cutters designed for efficient and accurate thread production in a wide range of materials and thread specifications.
About Thread Milling Cutters
MZG Tool Group's thread milling cutters are precision-engineered tools designed for creating internal and external threads through a milling process. Unlike traditional tapping, thread milling offers greater flexibility, reduced risk of tool breakage, and the ability to produce threads in hardened materials.
Our thread milling cutters feature optimized geometries and premium coatings to ensure precise thread profiles, extended tool life, and superior surface finishes. The thread milling process allows for the production of threads in a wide range of materials, from aluminum to hardened steels and exotic alloys.
All MZG thread milling cutters are manufactured to precise tolerances and undergo rigorous quality control to ensure exceptional performance and reliability. Our technical experts are available to help you select the right thread milling solution for your specific application.

Thread Milling Parameters
Proper thread milling parameters are essential for optimal results. MZG provides comprehensive cutting data recommendations for each thread milling cutter, including cutting speeds, feed rates, and programming guidance.
Thread Milling vs. Tapping
Feature | Thread Milling | Tapping |
---|---|---|
Tool Breakage Risk | Low - tool can be easily retracted | High - especially in blind holes |
Thread Size Flexibility | One tool for multiple sizes | One tap per thread size |
Hardened Materials | Excellent capability | Limited capability |
Thread Direction | Both left and right-hand with same tool | Requires specific tap for each direction |
Chip Evacuation | Excellent - small chips | Challenging in deep holes |
Thread Quality | High precision and surface finish | Good for standard applications |
Programming Complexity | Higher - requires helical interpolation | Lower - linear movement |
