The Carmex MTB Through-Coolant Solid Carbide Thread Mill is engineered for precision Whitworth threading, delivering reliable internal threads in demanding metalworking applications. With a through-coolant bore and MT7 shank, this tool blends durability with production-grade efficiency for engineers and machinists who demand consistent, high-quality results.

• Through-Coolant Bore: Coolant is delivered through the tool core to the cutting edge, enhancing chip evacuation from the hole and cooling the tool for improved performance and longer life.
• Solid Carbide Construction: Robust, wear-resistant substrate provides stable cutting performance and excellent resistance to high-temperature wear.
• Whitworth Thread Form Compatibility: Specifically designed for Whitworth BSW and BSF threads, catering to 1/2 inch nominal size with a precise 16 TPI thread pitch.
• MT7 Shank: Morse Taper 7 shank offers rigid, accurate mounting on compatible milling machines for repeatable results.
• Optimized Thread Milling Geometry: Specialized flute geometry and reliefs tailored for clean, accurate Whitworth thread profiles and smooth chip formation.

This tool is ideal for production environments requiring consistent Whitworth threads in steel and other metals, where through-coolant cooling reduces heat buildup and chip clogging, extending tool life and improving hole quality. Use cases include precision fastener holes, hydraulic and pneumatic components, and automotive or aerospace assemblies where exacting Whitworth specifications matter. By pairing the MTB thread mill with a compatible MT7 spindle, operators can achieve tight tolerances, reduced cycle times, and dependable performance across multiple batches.
