Carmex Thread Mills Carbide Mini Type - Metric - M20 x 2.5 - MT7

The Carmex Carbide Mini Type Thread Mill is a high-performance threading tool designed for fast, precise thread milling at M20 x 2.5 with MT7 carbide grade. Built for high-speed machining, it delivers dependable internal and external threads with a single tool across a wide range of pitches.

• Metric threading size: M20 x 2.5, MT7 carbide grade for robust performance.
• Carbide with TiAlN multi-layer coating: Sub-Micron grain with a triple TiAlN coating (ISO K10-K20) for long life and heat resistance.
• Internal and external threading: One tool cuts both sides of a threaded hole or a threaded shaft with consistent results.
• Coolant-through flutes: Integrated channels optimize chip evacuation and cooling in deep holes.
• Short profile, multi-flute design: 3–5 spiraled flutes reduce machining time and provide smooth cutting action; low cutting forces minimize vibration and prevent broken taps.
• Deep-hole threading capability: Specifically advantageous for threading in long, deep holes with reliable flushing.
• Material compatibility: Suitable for a broad range of materials, including hardened steels up to 45 HRc.
• Durability and versatility: Enhanced tool life due to triple coating and the ability to cover a wide range of thread pitches with a single tool.

With this thread mill, you gain flexibility to thread complex components without swapping tools, enabling shorter cycle times and fewer tool changes. The coolant-through design improves surface finish and hole quality in deep cavities, while the ability to mill both internal and external threads reduces inventory needs. Ideal for aerospace, automotive, and general precision machining where deep-hole threading and hard-material performance are essential. Whether you're threading through blind holes or through-holes, this MT7 carbide mini thread mill delivers reliable performance and consistent results across multiple pitches.
