Description
These Carmex Thread Mills Carbide are single-point, 55-degree partial-profile tools designed for threading deep parts. They’re built for both internal and external threads, delivering precise results across a wide range of pitches and profiles.
- Material & Coating: Carbide substrate with an ultra-fine sub-micron grade and triple blue PVD coating for enhanced wear resistance and longer tool life.
- Geometry: 55° partial-profile design optimized for deep-bores and challenging cavity threading, helping maintain accurate thread form.
- Flute Configuration: Three-flute construction combines rigidity with efficient chip evacuation for cleaner finishes.
- Shank: MT11 shank compatibility for secure, standard CNC toolholding and straightforward integration.
- Thread Capabilities: Supports a broad range of pitches and profiles and works with both internal and external threads; suitable for ISO metric M1.6 x 0.25 and 0-80 UNF sizes.
- Applications: Ideal for threading deep features and long holes where conventional thread mills struggle, delivering consistent, high-quality threads.
Designed to tackle demanding threading tasks with reliability, this thread mill line offers a practical, durable solution for precision manufacturing. The combination of carbide hardness, advanced coating, and a purpose-built 55° geometry translates to reliable performance, reduced tool changes, and better surface finishes in deep-part threading projects.
