Engineered for precision threading in metalwork, the Carmex MTB Thread Mills are a solid carbide solution designed to deliver clean Whitworth BSW/BSF threads in through-holes. With an MT7 shank and through-bore coolant, this tool helps you achieve reliable cuts and longer tool life in demanding applications.

• Through-Coolant Bore: Coolant is delivered directly through the bore to the cutting edges for efficient chip evacuation and effective temperature control, reducing re-cutting and extending tool life.
• Solid Carbide Construction: High-hardness carbide provides exceptional wear resistance and rigidity for consistent threading in tough metals.
• MT7 Shank: Standard MT7 drive offers strong coupling and precise alignment on compatible machines for repeatable results.
• Whitworth Thread Forms: Precisely formed for Whitworth BSW/BSF threading, ensuring accurate, repeatable threads in the British standard.
• Diameter Ranges: Available in two ranges—1/2–9/16 in and 3/4–13/16 in—to match common Whitworth thread sizes and practical through-hole work.
• Cutting Length: x12 designation corresponds to a 12-length cutting specification, providing a robust reach for threaded features.
• Multi-Edge Cutting Design: Optimized flute geometry supports efficient material removal and smooth, consistent thread milling.

This thread milling tool is ideal for shops that require reliable Whitworth threading in through-holes, such as mechanical assemblies, gearbox housings, and precision jigs. The through-coolant feature helps maintain steadier temperatures, improves surface finish, and reduces the likelihood of built-up edges, delivering consistent results across multiple parts and shifts. With its solid carbide construction and MT7 interface, it stands up to repeated use in demanding production environments while keeping cutting costs favorable over the tool’s life.
