The Carmex Thread Mills Solid Carbide with Through Coolant is built for precision internal threading on imperial Whitworth BSW/BSF standards, using a robust MT7 shank for dependable performance in CNC milling centers.

• Through Coolant: Coolant is delivered through the bore to the cutting edges, aiding chip evacuation and reducing heat buildup for cleaner threads and longer tool life.
• Solid Carbide Construction: Rigid, wear-resistant substrate designed to maintain thread form and finish even in demanding metals.
• Whitworth BSW/BSF Compatibility: Specifically engineered to produce accurate Whitworth threads, ensuring fit and function in imperial-threaded components.
• Dual Diameter Options: Available in 5/8" and 7/8" major diameters with 11 threads per inch, enabling flexible use on common Whitworth applications.
• MT7 Shank: Precision MT7 interface for secure, repeatable seating on compatible CNC milling machines and tool changers.
• Optimized Thread Milling Geometry: Designed to create precise internal threads with efficient chip control and consistent surface quality.

This tool is ideal for production and repair environments where reliable Whitworth threading is required in bores. The through-coolant design minimizes chip congestion in deep or awkward holes, reduces cutting temperatures, and support longer tool life, which translates to fewer tool changes and higher uptime. By maintaining accurate thread form and smooth finishes, it helps reduce post-processing time and improves part interchangeability in assemblies that rely on BSW or BSF threads. Whether you’re finishing a precision gearbox housing, hydraulic manifold, or other imperial-threaded components, this Carmex thread mill delivers consistent performance and value.
