The Carmex Thread Mills Carbide - Single Point is a precision internal-thread milling tool designed for small-diameter holes. It’s ideal for machinists needing accurate, repeatable internal threads in compact components.
- No. 1 x 72 size with MT11 shank: Compact form factor paired with a rigid MT11 interface for stable milling on standard CNC machines.
- Internal thread milling capability: Cuts internal threads, including ISO metric sizes (M1 x 0.25) and standard UNF threads (0-80), enabling versatile part fabrication.
- UN thread profiles supported: Compatible with UNC, UNF, UNEF, and UNS thread forms to cover common assembly standards.
- Full-profile, multi-flute geometry: 3–4 flutes deliver strong rigidity and efficient chip evacuation for clean thread forms.
- Carbide with Ultra-fine sub-micron grade: High-precision cutting edge for crisp thread geometry and long tool life.
- Triple blue PVD coating: Enhanced wear resistance and corrosion protection in demanding materials.
- Depth capability: Thread depth up to 3.5x the thread diameter, depending on profile and hole geometry.
The tool enables precise, consistent internal threads in tight spaces, reducing the need for tapping and post-processing. The full-profile geometry minimizes thread distortion while delivering a smooth surface finish across the threaded area. The MT11 shank provides rigidity for stable milling, supporting higher feed rates and shorter cycle times. The triple blue PVD coating lengthens tool life in tough alloys and aluminum, making this thread mill a cost-effective choice for high-mix, low-volume jobs or high-volume production alike. Ideal applications include precision housings, sensor enclosures, hydraulic fittings, and other small-diameter components where reliable thread engagement matters.
