The Carmex Thread Mills Carbide Mini Type is a compact, high-performance threading tool designed for machinists who need precise internal and external threads in a variety of materials. It’s built for UN thread families (UNC, UNF, UNEF, UNS) at 1/4" x 20, with MT7 carbide and a 14 mm reach to tackle deep-hole threading in a single setup.

• Thread compatibility: UN thread family (UNC, UNF, UNEF, UNS) 1/4" x 20
• Material and coating: MT7 carbide, Sub-Micron grade with Titanium Aluminium Nitride multi-layer coating (ISO K10–K20)
• Flute design: Spiral flutes with 3–5 flutes for smooth cutting and efficient chip evacuation
• Coolant through flutes: Through-flute coolant delivery enhances deep-hole processing and chip removal
• Reach and geometry: 14 mm reach with a short profile to maximize rigidity in deep holes
• Hole and material versatility: General-purpose tool suitable for a wide range of materials, including hardened workpieces up to 45 HRc
• Speed and efficiency: Optimized for medium to high cutting speeds, reducing overall machining time
• Durability: Triple-coated surface delivers longer tool life and reliable performance
• Operational reliability: Designed to minimize cutting forces and the risk of tool breakage in challenging threading tasks
• Versatility in usage: One tool capable of producing multiple thread pitches and both internal and external threads

This thread mill is ideal for precision applications where deep-hole threading, reliability, and material versatility matter—think molds, hydraulic components, automotive fixtures, and aerospace fittings. By combining a robust MT7 carbide core with a TiAlN multi-layer coating and a through-flute coolant path, it delivers consistent thread quality, reduced cycle times, and extended tool life, even when threading hardened materials.
