Carmex Thread Mills Carbide Mini Type - UNJ (UNJC UNJF UNJEF UNJS) - No. 6 x 32 - MT7

The Carmex Thread Mills Carbide Mini Type UNJ are compact, high-performance tools designed for precise internal and external threading in tight spaces. Built for machinists who demand versatility, long tool life, and dependable results across a range of materials.

• Threading capability: Produces both external and internal threads with a single tool across a wide range of pitches
• Size and shank: No. 6 x 32 with MT7 shank for compatibility with standard CNC tooling
• Material and coating: Sub-micron MT7 carbide with a TiAlN multi-layer coating (ISO K10–K20) for enhanced wear resistance
• Hole threading and coolant: Through-flute coolant delivers effective cooling in deep-hole applications
• Geometry and efficiency: Spiral flutes provide smooth cutting action; multi-flute design (3–5 flutes) reduces machining time
• Performance with hard materials: Suitable for machining hardened materials up to 45 HRC with controlled cutting forces thanks to the short profile
• Versatility: Optimized for deep-hole threading and a wide range of thread types and pitches, all with one tool

This thread mill delivers reliable, high-precision threads with reduced cycle times and extended tool life. The through-coolant capability helps manage heat in deep holes, while the triple-coated TiAlN surface minimizes wear during repeated passes. Ideal for shops that need flexible threading solutions in tight cavities, this tool supports efficient setups and consistent results across numerous materials and thread configurations.
