Meet the Carmex MTB solid carbide thread mill with through coolant—designed for precision threading in UNC/UNF/UNEF/UNS applications. It’s ideal for machinists and engineering shops that demand clean threads, reliable tool life, and efficient chip removal in hole threading.
- Size and thread form: 5/16" diameter with 24 TPI, compatible with UN, UNC, UNF, UNEF and UNS thread standards.
- Material: Solid carbide for rigidity, wear resistance, and high-speed performance in demanding materials.
- Through coolant: coolant is delivered through the bore to the cutting edges for effective cooling and chip evacuation.
- Shank: MT7 interface for broad machine compatibility and stable toolholding.
- Thread milling geometry: optimized flute and cutting geometry engineered to produce accurate, consistent threads in through-holes.
- Durability: engineered to extend tool life in repetitive threading operations, reducing downtime and replacement costs.
Through-coolant threading minimizes heat buildup and chip buildup inside the hole, helping maintain thread form and tolerances. The solid carbide construction supports higher speeds and tougher materials, enabling faster cycle times without sacrificing quality. With MT7 compatibility, setup is straightforward across a wide range of milling centers. This Carmex MTB thread mill is well-suited for production runs, repair work, or any project requiring reliable, precise threads in aluminum, steel, and other alloys.
