Carmex Thread Mills Carbide deliver precise, reliable threading with through-coolant—the perfect single-point solution for machinists who need clean, accurate internal and external threads in a wide range of materials. Built around a 60° partial-profile geometry, these MT11 shank mills optimize chip evacuation and surface finish in demanding through-spindle cooling setups.

• Through-coolant design: internal coolant channels in the flutes maximize chip removal and heat control for consistent cuts and extended tool life.
• 60° partial-profile: dedicated 60-degree threading geometry provides stable form and reliable thread mating across applications.
• Internal and External threading: versatile tooling that handles both thread types without swapping tools.
• Pitch range: supports small pitches down to 0.5 mm (internal) and 0.4 mm (external) for fine, precise threads.
• Depth capability: capable of cutting threads up to 50 mm deep, enabling deep-thread applications in tight pockets or through holes.
• Flute configuration and material: 4–5 flutes on a MT8 sub-micron carbide substrate for smooth, controlled cutting.
• Coating: advanced PVD triple coating (ISO K10–K20) delivers excellent wear resistance and heat tolerance.
• Shank and compatibility: MT11 Morse taper shank ensures secure, rigid mounting on a wide range of milling machines.
• General-purpose performance: designed as a reliable, all-material threading tool for general machining environments.

This line builds on the MTI partial-profile concept by integrating through-coolant to prevent chip buildup and sustain high performance over longer tool life. The combination of multiple flutes, a hard carbide substrate, and a triple PVD coating enables smooth cutting, steadier thread form, and consistent finishes even on tougher materials. Whether you’re threading small-diameter holes, threaded pockets, or external threads on a sleeve, these Carmex mills offer dependable precision, reduced maintenance, and a streamlined setup—making them a solid choice for automotive, aerospace, and general manufacturing workflows.
