Engineered for precision threading in demanding environments, Carmex MTB Solid Carbide Thread Mills with Through Coolant deliver dependable, through-bore cooling for UNC/UNF threading. Built for shops that perform internal thread milling in tough materials, these tools combine durability with process efficiency.

• Through coolant bore: Coolant is delivered directly through the tool bore to flush chips from deep holes and carry heat away from the cutting edges, helping maintain stable cutting conditions.
• Solid carbide construction: Premium carbide substrate provides high hardness and wear resistance for consistent thread quality over long runs.
• Thread forms supported: Compatible with UNC, UNF, UNEF, and UNS internal threads, specifically 7/16 x 14.
• MT7 shank: Morse Taper 7 shank for secure seating in compatible milling machines, reducing runout and vibration.
• Optimized geometry: Flute design and rake optimized for smooth chip evacuation and clean thread profiles.

Through coolant capability minimizes chip buildup and heat in deep threading operations, extending tool life and enabling higher material removal rates. The MTB design translates to more consistent hole quality, fewer tool changes, and reliable performance across common machining materials. Ideal for precision internal threading in production environments where uptime and accuracy matter.
