The Carmex Thread Mills Carbide Mini Type with MT7 coating is a precision threading solution designed for machinists who need fast, reliable internal and external threads in deep holes. Built for high-speed performance across a range of materials, it delivers consistent results with fewer tool changes.

• Material and coating: Carbide MT7 substrate with a sub-micron TiAlN multi-layer coating for enhanced hardness and heat resistance (ISO K10-K20).
• Threading capability: Produces both external and internal threads in UNC/UNF/UNEF/UNS standards; available in No. 2 and No. 3 x 56 length.
• Through-coolant design: Coolant through the flutes provides efficient cooling in deep holes, improving surface finish and tool life.
• Flute geometry: Spiral flutes enable smooth cutting action and reduced chatter during milling.
• Short profile: Compact profile lowers cutting forces, contributing to shorter machining times and steadier operations.
• Depth capability: Optimized for deep-hole threading, expanding the range of projects you can tackle with a single tool.
• Durability: Triple coating extends tool life, delivering more cycles per job and better value over time.
• Material versatility: Suitable for hardened materials up to 45 HRc and serves as a general-purpose thread mill across various alloys and steels.

By combining deep-hole capability with high-speed threading and durable coating, this MT7 mini thread mill helps you achieve precise threads with fewer tool changes and reliable performance in challenging applications. It’s an ideal choice for shops aiming to improve throughput in automotive, aerospace, and moldmaking tasks where deep, accurate threads are critical.
