Meet the Carmex MTB Solid Carbide Thread Mill with Through Coolant — a precision threading tool designed for pro shops that demand reliable chip evacuation, cooler operation, and consistently accurate holes. Built for through-coolant systems, it handles 7/16 to 1/2-28 UNC/UNF/UNEF/UNS threads with MT7 compatibility, delivering dependable performance in demanding environments.
- Through-Coolant Bore: Coolant flows through the bore to flush chips from the threaded hole and keep the cutting zone cool for steady, uninterrupted threading.
- Solid Carbide Construction: Rugged, wear-resistant material that maintains precise thread geometry under high-speed milling.
- MT7 Shank Interface: Designed for a rigid MT7 tool holder, ensuring stability and accuracy during demanding threading operations.
- Thread Forms Supported: Optimized for UNC, UNF, UNEF, and UNS forms in the 7/16 to 1/2-28 size range for versatile applications.
- Optimized Thread Milling Geometry: Engineered cutting geometry tailored for clean, consistent threads with minimal tool deflection.
This MTB through-coolant thread mill reduces downtime by enabling efficient chip removal and cooling, which helps extend tool life and improve hole quality. The combination of solid carbide and a through-coolant design delivers reliable performance across common threading jobs in metalworking, from small fasteners to precision fasteners in aerospace, automotive, and general manufacturing. For best results, pair with a compatible through-coolant setup and ensure proper workholding to maintain tight tolerances and smooth thread finish.
