Carmex Thread Mills Carbide Mini Type is a compact, high-performance threading tool designed for UNC/UNF/UNEF/UNS threads in tight bore sections. Built for machinists who demand precision and efficiency, this 1/4-20 thread mill combines long reach with strong carbide and a through-coolant design for deep-hole threading.

• Threading size: 1/4-20 UNC/UNF/UNEF/UNS threading capability for internal and external threads
• Material and coating: MT7 sub-micron carbide with TiAlN multi-layer coating (ISO K10–K20) for wear resistance and heat tolerance
• Reach and geometry: Long mini-type tool with a 19 mm reach, optimized for deep holes
• Flute design: Spiral flutes with 3–5 cutting edges for smooth cutting and efficient chip evacuation
• Coolant and deep-hole performance: Through-flute coolant enables effective cooling and flushing in deep bores
• cutting performance: Suitable for medium to high cutting speeds and shorter machining times due to the short-profile design
• Versatility: One tool can produce a wide range of thread pitches and can create both internal and external threads
• Material capability: Capable of machining hardened materials up to 45 HRC
• Durability: Triple coating extends tool life and reduces wear under demanding machining conditions

With the Carmex Mini Type thread mill, you gain consistent, accurate threading in hard-to-reach bores without the risk of tap breakage. The through-coolant design and multi-flute geometry ensure clean, stable thread profiles even at elevated speeds, while the long 19 mm reach reduces setup time by allowing threading from a single access point. Its versatility—handling multiple pitches and both internal and external threads—simplifies production workflows and minimizes tool changes, helping you deliver precise components faster with reliable performance.
