Description
The Carmex MTZ Through-Coolant Carbide Thread Mill is built for precision threading in through-holes, delivering coolant directly through the flutes to the cutting edge for smoother, more reliable cuts. Tailored for BSF and BSP threads with a 55-degree profile, it’s a dependable choice for shops that demand consistent thread forms and long-lasting tooling.
- Through-Coolant Flutes: Coolant is delivered directly to the cutting edge via the flutes, improving heat management and chip control for steady cutting performance.
- Carbide Construction: Made from high-hardness carbide for enhanced wear resistance, rigidity, and extended tool life in demanding threading work.
- 55° Thread Profile (G): Specifically designed to produce accurate BSF and BSP threads with the correct 55-degree angle for reliable engagement.
- Designed for Through-Hole Threading: Optimized geometry enables efficient threading of through-holes with direct chip evacuation, reducing chip buildup and chatter.
- Machine Compatibility: Effective on systems without external coolant, offering flexibility in setups and preserving throughput in compact or older machines.
- Shank: MT7 shank provides a robust, secure fit with compatible tool holders for stable operation at high cutting speeds.
- Size: x 12, as specified in the product title, reflecting the tool’s dimension for precise fit in your milling setup.
The MTZ thread mill delivers reliable through-hole threading with excellent surface finish and repeatable results. By guiding coolant through the tool, it reduces heat buildup at the cutting edge, extending tool life and maintaining accuracy across multiple threads. The through-coolant design also simplifies setups on machines without external coolant systems, making this tool a versatile option for plumbing, fastener, and valve housing applications where BSF/BSP threads are required. With its MT7 shank and dedicated 55-degree geometry, you can expect consistent thread form, reduced cycle times, and improved productivity in everyday machining tasks.
