Carmex Thread Mills Carbide Mini Type - Metric - M8, M10, M12 x 1.25 - MT7 - Long

The Carmex Thread Mills Carbide Mini Type is a versatile, high-precision threading tool designed for machinists who need fast, reliable metric threads in tight spaces. This long-type mill handles M8, M10, and M12 x 1.25 threads with a single, durable solution that excels in deep-hole applications.

• Tool type: Carbide mini-type thread mill with long length (MT7) for reaching deep pockets and challenging geometries.
• Thread range: Produces M8 x 1.25, M10 x 1.25, and M12 x 1.25 threads using one tool, reducing setup changes.
• Material & coating: MT7 sub-micron carbide core with a Titanium Aluminum Nitride (TiAlN) multi-layer coating (ISO K10–K20) for wear resistance and longevity.
• Cutting speed: Optimized for medium to high cutting speeds to maximize productivity without compromising precision.
• Coolant through flutes: Through-flute coolant enhances cooling and chip evacuation, especially effective for deep-hole threading.
• Flute design: Spiral flutes deliver a smooth, stable cutting action with reduced vibration.
• Flute count: Multi-flute configuration (3–5 flutes) lowers cycle time and improves material removal efficiency.
• Depth capability: Specifically advantageous for machining in deep holes and hard-to-reach features.
• Hardness compatibility: Suitable for threading hardened materials up to 45 HRc, expanding its range of applications.
• Reliability: Short profile minimizes cutting forces and helps prevent tool breakage during demanding threading operations.
• Versatility: Capable of producing both internal and external threads with the same tool, simplifying setups and inventories.

Designed for small- to mid-sized production, this long, high-performance thread mill delivers precise thread forms, consistent pitches, and reliable tool life across a range of materials. The combination of a hardened MT7 carbide core, TiAlN coating, spiral flute geometry, and through-coolant capability makes it ideal for automotive components, hydraulic fittings, mold work, and precision mechanical assemblies where deep threading and fast cycle times matter. Use with stable fixturing and proper coolant pressure to maximize wear life and achieve clean, accurate threads every time.
