Introducing the Carmex MTZ Through-Coolant Thread Mill—a carbide threading tool designed for through-hole work and Whitworth BSW/BSF threads. With coolant delivered directly through the flutes to the cutting edge, it enables precise, efficient threading even on machines without external coolant systems.
- Through-Coolant Flutes: Coolant is guided through the tool’s flutes directly to the cutting edge for targeted cooling and effective chip flushing.
- Carbide Construction: Rugged, wear-resistant solid carbide for long tool life and stable thread geometry under demanding conditions.
- MT7 Shank: Robust MT7 shank design for secure mounting and broad compatibility with a wide range of CNC toolholders.
- Whitworth BSW/BSF Thread Forms: Specifically engineered for Whitworth BSW and BSF threading in sizes spanning 7/16" and 5/8" with 11/16"-14 pitch.
- Through-Hole Thread Milling: Optimized geometry for threading through holes with direct chip removal to maintain uninterrupted cutting progress.
- Direct Chip Removal & No External Coolant Required: Efficient chip evacuation and cooling that support coolant-less setups, expanding where threading can be performed.
This MTZ tool combines precise thread formation with practical manufacturing benefits: improved surface finish, consistent thread profiles, and higher uptime by simplifying coolant needs and chip management. Ideal for production environments that require reliable Whitworth threading in through-hole components while maintaining flexibility across diverse CNC machines.
