The Carmex Thread Mills Carbide Mini Type is a compact, high-precision threading tool designed for No. 8 x 32 threads in UNC, UNF, UNEF and UNS specs. Built for deep-hole work, its long reach and robust MT7 carbide core deliver reliable threading performance across a range of materials.

• Threading versatility: Produces both internal and external threads with a single tool, enabling flexible setup and reducing tool changes.
• Size and reach: No. 8 x 32 thread size with a 12.5 mm reach, ideal for accessing deeper cavities without a secondary tool.
• Material and coating: MT7 sub-micron carbide core with a TiAlN multi-layer coating (ISO K10–K20) for extended life at higher speeds.
• Flute design: Spiral flutes provide smooth cutting action and effective chip evacuation, supporting stable feeds in challenging workpieces.
• Cutting speed and forces: Optimized for medium to high cutting speeds with a short profile that lowers cutting forces and reduces the risk of breakage.
• Through-coolant efficiency: Coolant through the flutes enhances heat removal and chip flushing in deep-hole applications.
• Depth capability: Designed to excel in deep-hole threading, enabling efficient machining of long threaded features.
• Hard-material performance: Suitable for machining hardened materials up to 45 HRc, expanding its application to hardened steels.
• Durability: Triple-layer coating and optimized geometry contribute to longer tool life and more consistent results over many cycles.

Designed for precision-focused shops, this carbide mini thread mill delivers accurate thread profiles, reduces cycle times, and minimizes tool changes in deep-hole applications. Whether threading through hardened steel or standard alloys, it maintains clear, consistent threads with through-coolant support and a geometry tuned for reliability and efficiency.
