Carmex Thread Mills Carbide Mini Type MT7 are compact, high-performance tools designed for precision thread milling in tight spaces. They deliver reliable internal and external threading at high speeds with extended tool life, even in challenging materials.

• Size and Pitch: Metric threading for M5 and M6 with 0.35 mm pitch, optimized for compact applications and versatile in-workpiece access.
• Carbide Grade and Coating: MT7 sub-micron carbide with a TiAlN multi-layer coating (ISO K10–K20) for exceptional wear resistance and heat tolerance.
• Coolant-Through Flutes: Integrated coolant channels through the flutes enhance chip evacuation and cooling, especially effective in deep-hole threading.
• Flute Design and Count: Spiral flutes with 3–5 cutting edges provide smooth cutting action and shorter machining times.
• Internal and External Threading: A single tool can produce both internal and external threads, reducing tool changes and inventory needs.
• Material Compatibility and Speed: General-purpose threading for all materials with capability for hardened workpieces up to 45 HRc at medium to high cutting speeds.
• Durability and Reliability: Short profile reduces cutting forces and deflection, while the triple coating extends tool life in demanding production environments.

In practical terms, this mini MT7 thread mill enables deep-hole threading with dependable performance, delivering precise thread profiles, cleaner finishes, and faster cycle times. The combination of a hard MT7 carbide core, TiAlN coating, and coolant-through design means you can tackle tough materials and tight geometries with confidence, using the same tool for a wide range of thread sizes and pitches. This makes it an ideal choice for precision assemblies, aerospace and automotive components, and any application requiring robust, high-speed threading in confined spaces.
