The Carmex Carbide Mini Type UNJ Thread Mill is a precision threading tool designed for engineers who need accurate UNJ, UNJC, UNJF, UNJEF, and UNJS threads in tight or deep holes. Built for high-speed performance and long tool life, it handles a broad range of materials with consistent results.
- Thread forms supported: UNJ, UNJC, UNJF, UNJEF, UNJS for versatile compatibility in a single tool
- Sizes: No. 8 and No. 10 x 32 for common miniature thread pitches
- Material and coating: Sub-micron MT7 carbide with a TiAlN multi-layer coating (ISO K10–K20) for excellent wear resistance
- Cutting performance: Optimized for medium to high cutting speeds with smooth, controlled removal of material
- Coolant through the flutes: Through-spindle coolant enhances chip evacuation and cooling in deep-hole applications
- Flute design: Spiral flutes provide a steady cutting action and reduced vibration
- Flute count and machining time: 3–5 flutes deliver efficient material removal and shorter cycle times
- Deep-hole capability: Specifically designed to enable threading in deep or confined holes with reliable stability
- Versatility: A single tool can produce a wide range of thread pitches and both external and internal threads
- Durability: Triple-layer coating boosts tool life, even under demanding machining conditions
- Material hardness tolerance: Suitable for hardened materials up to 45 HRc, expanding its applications
This mini-type thread mill reduces cycle times without sacrificing precision. The short profile lowers cutting forces, helping prevent broken taps and improving stability in challenging setups. The combination of MT7 carbide, TiAlN coating, and through-coolant support makes it a reliable choice for deep-hole threading, high-speed production, and general-purpose threading across a broad material range.
