Carmex Carbide Mini Thread Mills are compact, high‑performance tools designed for precise internal and external threading in deep holes. Built for flexible UN thread profiles and hard materials, they’re ideal for machinists seeking efficient, versatile threading with minimal tool changes.

• Thread size & type: 1/4-28 UN thread profile compatible with UNC/UNF/UNEF/UNS variants, enabling broad threading options with a single tool
• Material & coating: MT7 sub‑micron carbide with a TiAlN multi‑layer coating (ISO K10–K20) for exceptional wear resistance and heat management
• Flute design: Spiral flutes with 3–5 flutes for smooth cutting action and efficient chip evacuation
• Through‑coolant capability: Coolant through the flutes provides effective cooling and debris removal in deep holes
• Depth reach: Long version engineered to reach deep holes without sacrificing rigidity or accuracy
• Speed & efficiency: Optimized for medium to high cutting speeds, delivering shorter machining times
• Versatility: The same tool can produce a wide range of thread pitches and both external and internal threads
• Material hardness: Capable of machining hardened materials up to 45 HRC, expanding its application range
• Durability: Triple coating and a short profile reduce cutting forces and extend tool life, even under demanding cycles

This thread mill is designed to streamline production: it enables deep‑hole threading with a single, reusable tool, supports multiple thread standards without changing tools, and maintains stability at higher speeds thanks to its short profile and robust coating. For workshops that routinely thread into challenging materials or require quick changeovers, this carbide mini thread mill delivers reliable performance, consistent thread quality, and longer tool life—reducing downtime and improving throughput.
