Carmex Thread Mills Carbide - Single Point is a precision internal-thread milling tool designed for small-diameter work. Built for CNC machining, it enables clean, accurate ISO M1 x 0.25 and 0-80 UNF threads in tight spaces.
- Thread milling type: Full-profile internal-thread mill designed for robust, accurate internal threading in hard-to-reach locations.
- Supported thread sizes: ISO metric M1 x 0.25 and 0-80 UNF threads, covering ultra-small to fine-pitch applications.
- Depth capacity: Thread depth up to 3.5 × Thread Diameter, depending on the profile, allowing deeper threads in a single pass where geometry permits.
- Flute count: 3–4 flutes for efficient chip evacuation and stable cutting in constrained cavities.
- Material and grade: Carbide construction with MT11 Ultra-fine sub-micron grade for high-precision performance.
- Coating: Triple blue PVD coating to reduce wear, lower friction, and extend tool life in demanding materials.
- Shank/interface: MT11 shank designed for secure fit and reliable alignment in compatible milling centers.
- Application: Optimized for internal thread milling, delivering consistent thread profiles and tight tolerances on miniature features.
This tool pairings a rigid carbide composition with an advanced coating and a refined flute geometry to deliver precise internal threads with minimal runout. The MT11 Ultra-fine grade supports fine pitches and small diameters, while the triple blue PVD coating helps resist wear during extended cutting cycles. With a versatile depth capacity and multi-flute design, it’s well-suited for micro-threads in lightweight components, instrumentation housings, and other compact assemblies where reliable internal threading is critical.
