Carmex Thread Mills Mini Type are carbide threading tools designed for precision metric M3 x 0.5 work, featuring a long 6.5 mm reach and MT7 shank. Built for high-speed threading in tight spaces, they’re ideal for shops that demand reliable performance in deep holes and challenging materials.

• Material & coating: MT7 sub-micron carbide with a TiAlN multi-layer coating (ISO K10–K20) for durability at higher speeds.
• Shank & reach: MT7 shank with a long 6.5 mm reach, optimized for accessing deep cavities and threaded features without frequent tool changes.
• Threading versatility: One tool can produce a wide range of thread pitches and works for both external and internal threads.
• Cutting geometry: Spiral flutes provide a smooth cutting action, while the short profile reduces cutting forces and improves stability.
• Coolant & chip evacuation: Coolant-through flutes enhance heat removal and chip control in deep-hole applications.
• Flute count & life: Multi-flute design (3–5 flutes) enables faster machining and contributes to longer tool life thanks to the triple coating.
• Material capability: Suitable for high-speed machining across materials, including hardened workpieces up to 45 HRc.

This tool is engineered to minimize cycle times and maximize uptime. The combination of a robust MT7 shank, deep-reach geometry, and TiAlN coating delivers consistent thread quality in demanding environments, making it a dependable choice for precision threading tasks in automotive, aerospace, and mold-making applications.
