The Carmex MTB Thread Mills are high-precision solid carbide tools built for reliable internal thread milling in UN/UNC/UNF/UNEF/UNS specifications. Designed for shops that require repeatable, accurate threads and longer tool life, they feature through-bore coolant to keep chips moving and the cutting edge cooled for better performance.

• Thread size: 7/16-14 (7/16 x 14) in UN thread forms, supporting UNC/UNF/UNEF/UNS variants.
• Shank: MT7 Morse taper shank for secure, quick changes in compatible holders.
• Material: Solid carbide for rigidity, wear resistance, and stable cutting in demanding materials.
• Through-coolant: Through-bore coolant delivers coolant directly to the cutting edge, enhancing chip evacuation and reducing thermal buildup.
• Application: Optimized for precise internal thread milling in a range of machining applications and materials.

The through-coolant design actively removes chips from the machining hole, minimizing ensures of clogging and enabling smoother entry and deeper thread milling. The robust carbide construction stands up to repeated passes and higher cutting speeds, translating to longer tool life and lower tooling costs over time. With its MT7 shank and carefully engineered threading geometry, this MTB tool delivers clean, accurate threads and dependable performance in automotive, aerospace, mold-making, and general precision machining scenarios.
