Description
The Carmex Thread Mills Carbide Mini Type is a precision threading tool built for engineers and machinists who demand reliable internal and external threads in tight spaces, at speed, and with durable wear resistance.
- Thread form coverage: Compatible with UNC, UNF, UNEF, and UNS forms, enabling versatile threading in a single tool.
- Carbide MT7 Sub-Micron Grade: Ultra-fine grain carbide delivers exceptional edge retention and long tool life in a wide range of materials.
- TiAlN Multi-Layer Coating: Titanium aluminium nitride coating (ISO K10–K20) provides superior heat resistance and oxidation protection for high-speed threading.
- Coolant-Through Flutes: Integrated coolant channels efficiently flush chips in deep holes, reducing heat and improving surface finish.
- Spiral Flutes: Smooth cutting action with effective chip evacuation, enhancing stability in challenging workpieces.
- Multi-Flute Design (3–5 Flutes): More cutting edges yield shorter cycle times and better material removal at high speeds.
- Short Profile for Lower Cutting Forces: Compact geometry reduces load on the tool, increasing stability and reducing chatter.
- Internal & External Threading with One Tool: Capable of producing both internal and external threads, streamlining setups and tooling inventory.
- Hardened Material Capability: Suitable for machining hardened alloys up to 45 HRC, expanding application potential.
Designed for deep-hole threading and high-efficiency production, this mini thread mill delivers consistent thread quality, reduced cycle times, and extended tool life across common thread pitches. It’s an ideal choice for precision assemblies, automotive and aerospace components, and moldmaking where reliable, repeatable threads matter.
