The Carmex MTB Solid Carbide Thread Mills with Through Coolant are designed for precision internal threading on NPS forms, delivering cleaner threads and longer tool life for demanding machining environments. Built for machinists who value reliability and efficiency, this MTB tool leverages through-bore cooling to streamline chip evacuation and cut temperatures.

• Through-Coolant Bore: Coolant is fed through the bore to cool the cutting edges and flush chips from the hole, improving thread quality and reducing built-up edge.
• Solid Carbide Construction: Premium carbide provides high hardness and excellent wear resistance for durable performance in tough materials.
• NPS Thread Form Coverage: Specifically engineered for National Pipe Straight threads in the 1/4" to 3/8" range at 18 TPI.
• MT7 Shank: Rugged MT7 shank ensures a secure, rigid fit in standard CNC spindle systems for stable milling.
• Optimized MTB Geometry: Precision flute and cutting-edge geometry designed for smooth internal threading and reliable chip flow.

With through-coolant capability and a robust carbide build, this thread mill minimizes heat buildup, reduces cycle times, and extends tool life. It’s ideal for shop floors prioritizing consistent thread quality, reduced downtime, and cost-efficient maintenance in production and precision engineering applications.
