Meet the Carmex Carbide Mini Type MJ Thread Mill with MT7 shank — a compact, high-performance tool designed for deep-hole threading across a broad range of materials. With a 12 mm diameter and 1.75 mm pitch, it delivers fast, reliable threads in challenging holes.

• Thread mill size: 12 mm diameter, 1.75 mm pitch; MT7 taper for secure, versatile toolholding.
• Carbide grade and coating: MT7 sub-micron carbide with Titanium Aluminium Nitride multi-layer coating (ISO K10–K20) for wear resistance and heat management; triple coating extends tool life.
• Through-coolant design: Coolant through the flutes provides effective cooling and chip evacuation in deep-hole threading operations.
• Flute geometry: Spiral flutes enable smooth cutting action; 3–5 flutes reduce machining time while maintaining rigidity.
• Performance at speed: Optimized for medium to high cutting speeds, enabling shorter cycle times without sacrificing thread quality.
• Material versatility: General-purpose threading capable of machining a wide range of materials, including hardened workpieces up to 45 HRc.
• Threading versatility: A single tool can produce a wide range of thread pitches and can thread both internal and external features.
• Durability and reliability: Short profile lowers cutting forces and minimizes the risk of tap breakage, supported by a robust triple-coated carbide construction.

This MJ-thread mill is ideal for applications requiring deep-hole threading, high-speed cycles, and versatile pitch options—perfect for moldmaking, aerospace components, and precision automotive parts. The through-coolant design and spiral flute geometry help sustain accurate thread forms in challenging holes, while the tool’s hardened-material capability up to 45 HRc ensures dependable performance across demanding jobs. Simplify tooling with one durable, adaptable solution that delivers consistent thread quality and longer tool life.
