Meet Carmex MTB Thread Mills: a solid carbide threading tool designed for high-precision internal threads in through-holes. Built for durability and consistent results, this 3/4" diameter, 16 TPI tool uses an MT7 shank and is ready to handle UNC, UNF, UNEF, and UNS thread standards with through-coolant capability.

• Cutting Material: Solid carbide construction delivers rigidity and wear resistance for long tool life in demanding threading applications.
• Through-Coolant: Integrated coolant bore delivers fluid directly to the cutting edges, improving chip evacuation and reducing heat buildup.
• Shank Type: MT7 shank designed for secure, precise mounting in standard Morse Taper tool holders.
• Thread Compatibility: Optimized for UNC, UNF, UNEF, and UNS thread forms, enabling versatile threading across common fastener standards.
• Size: 3/4" diameter with 16 TPI pitch to suit mid-range thread requirements in through-hole work.

By delivering coolant through the bore, this thread mill minimizes chip clogging and thermal stress, extending tool life and maintaining precise thread tolerance across multiple passes. The MT7 shank provides stable rigidity at higher feeds and speeds, helping you achieve clean, precise threads with fewer passes. Ideal for automotive, aerospace, and general precision machining where reliable internal threads and long tool life are essential.
