The Carmex MTB Thread Mills are precision solid carbide tools designed for through-coolant thread milling in UN-series threads (UNC, UNF, UNEF, UNS). Built for machinists and precision engineering applications, they deliver clean, accurate threads with extended tool life.

• Through-Coolant Bore: Coolant is delivered through the bore to flush chips, maintain thread quality, and cool the cutting edges for deeper holes and tougher materials.
• Solid Carbide Construction: Rugged, wear-resistant material that provides consistent thread profiles and long tool life in demanding applications.
• MT7 Shank: Standard MT7 interface for reliable clamping and compatibility with a wide range of CNC machines.
• UN Thread Compatibility: Engineered to generate UNC, UNF, UNEF, and UNS threads with high accuracy and repeatable results.
• Size Range: 1" to 1-1/2" diameter with a 12" overall length, offering versatility for common threaded-hole applications.

By integrating coolant through the bore, these thread mills reduce chip buildup and heat, promoting smoother cuts, less post-process deburring, and longer tool life. The precision carbide composition and robust geometry deliver repeatable thread forms for critical assemblies in aerospace, automotive, and industrial equipment. The through-coolant design enhances performance in deeper holes and challenging materials, enabling faster cycle times and lower operating costs over the tool’s life.
