- Through-Coolant Flute Design: Coolant flows through the flute channels to the cutting edge, providing effective cooling and lubrication during threading for consistent results.
- Carbide Construction: Rigid, wear-resistant carbide offers long tool life and reliable performance across demanding materials.
- UN Thread Compatibility: Supports UNC, UNF, UNEF, and UNS threading with a 3/4"-16 pitch, covering common internal-thread standards.
- 3/4 x 16 Size: Precise major diameter and pitch tailored for standard through-hole applications.
- MT7 Shank: Built to fit a wide range of CNC spindles with a robust MT7 interface for strong retention and rigidity.
- Direct Chip Removal for Through-Hole Threading: Optimized flute geometry enables efficient chip evacuation, reducing clogging and improving cycle efficiency.
- Machine Compatibility: Effective even on machines without external coolant; integrated coolant delivery through the tool enhances versatility in diverse shop setups.
This MTZ through-coolant thread mill delivers precise, repeatable internal threads with excellent surface finish and dependable tool life. Ideal for applications that require through-hole threading in fastener standards, housings, manifolds, and other components, it combines efficient cooling, smart chip control, and a versatile MT7 shank to fit a wide array of CNC machines.
