Carmex Thread Mills Solid Carbide - With Through Coolant - UNJ (UNJC UNJF UNJEF UNJS) - 1/2 x 13 - MT7

Carmex MTB Solid Carbide Thread Mill with Through Coolant is built for precise internal threading in CNC workholding, designed to mill UNJ threads (including UNJC, UNJF, UNJEF, and UNJS) with a 1/2" diameter and 13 TPI, using an MT7 shank for broad machine compatibility.

• Through-Coolant Bore: Coolant flows directly through the tool bore to flush chips, control temperature, and maintain consistent thread quality during deep or complex holes.
• Solid Carbide Construction: Hardened carbide core delivers exceptional wear resistance and stability under demanding cutting conditions for repeatable results.
• UNJ Thread Form Compatibility: Optimized for UNJ thread profiles (UNJC/UNJF/UNJEF/UNJS), supporting a range of internal threading applications in a single tool.
• MT7 Shank Interface: Robust MT7 taper ensures reliable seating, alignment, and compatibility with a wide array of CNC milling centers.
• Size and Pitch: Precisely engineered for 1/2" diameter with 13 threads per inch, ideal for standard UNJ internal threading requirements.

The MTB through-coolant thread mill delivers dependable, high-quality internal threads while minimizing heat and chip buildup. By evacuating chips through the bore, it reduces the risk of recutting and surface defects, helping you achieve smooth hole finishes and accurate thread engagement. This tool is well-suited for high-volume production, precision components, and challenging materials where consistent thread performance and tool longevity matter most.
