Carmex Mini Type solid carbide thread mills are engineered to cut UNC/UNF/UNEF/UNS threads in hard materials, delivering precise profiles with a reliable surface finish. Designed for machinists working with hardened steels and tough alloys, this compact toolset keeps tolerance tight while standing up to demanding workloads.
- Diameter options: No. 3 and No. 4 thread mills, suitable for standard UN thread forms.
- Material and construction: Solid carbide for superior wear resistance and long tool life in hardened materials.
- Material compatibility: Optimized for hard workpieces up to 62 HRc, enabling reliable threading in tough alloys.
- Thread forms supported: Compatible with UNC, UNF, UNEF, and UNS thread profiles for versatile applications.
- Length and shank: 48 mm length of cut with MT9 Morse taper shank for secure mounting on compatible machines.
- Cutting performance: Precision flute geometry and robust construction reduce chatter and deliver a clean, consistent finish on every pass.
These thread mills empower precise internal and through-thread milling in hardened materials where tapping is impractical or prone to wear. The mini form combines compact reach with dependable rigidity, making it ideal for mold making, die work, and precision fastener applications where tight tolerances and surface quality matter. With the MT9 shank, they integrate smoothly into standard milling centers, supporting efficient, accurate thread production in challenging alloys.
