Carmex Thread Mills Mini Type is a solid carbide thread milling cutter designed for through-coolant threading in UN-family threads. Built for precision-driven shops, it delivers clean, accurate threads in through-holes with reliable tool life.

• Size: No. 1 x 72
• Shank: MT7
• Material: Solid carbide
• Coolant delivery: Internal through-coolant bore provides high-pressure coolant directly to the cutting edge and through the pre-hole, supporting chip removal during the threading circle
• Cutting type: Mini thread milling cutter (MTSB) for precise internal threading
• Thread compatibility: Suitable for UN family threads (UNC, UNF, UNEF, UNS) in through-holes
• Design benefit: Coolant through the tool enhances edge cooling and maintains cutting efficiency during extended cycles

The through-coolant bore is designed to wash away chips as you thread, while the coolant pressure actively cools the cutting edge. This combination helps sustain thread quality, reduces heat-related wear, and supports longer tool life, especially in harder materials or deeper holes. Ideal for applications where dependable UN-threaded through-holes are required—think automotive components, hydraulic fittings, and precision mechanical assemblies—where consistent thread form and reliable performance matter most.
