Meet Carmex Thread Mills Carbide — a single-point, full-profile tool crafted for precise internal threading in ACME and small-diameter applications. Built for professional machinists and precision shops, it delivers clean, repeatable internal threads with outstanding wear resistance.

• Threading capability: Internal thread milling with a full-profile design that supports ISO M1 x 0.25 through 0-80 UNF threads.
• Thread sizes: ACME internal thread mills for 3/8-12 and 7/16-12 threads.
• Cutting geometry: Single-point, full-profile tooling optimized for accurate internal thread formation.
• Flute count: Multi-flute configuration (3–4 flutes) for stable cutting and efficient chip evacuation.
• Material & grade: Carbide substrate with MT11 Ultra-fine sub-micron grade for exceptional rigidity and finish.
• Coating: Triple blue PVD coating to reduce wear and heat, extending tool life in demanding materials.
• Shank: MT11 compatibility for secure mounting in standard CNC spindles.
• Depth capacity: Thread depth can reach up to 3.5 × the thread diameter, depending on profile.

These features translate into real-world benefits: precise thread geometry with tight tolerances, smoother engagement of fasteners, and consistent results across production runs. The combination of carbide rigidity, advanced coating, and multiple flutes minimizes chatter and enhances surface finish inside the hole, while the MT11 shank and compact design streamline setup on CNC machines. Ideal for high-precision assemblies, mold work, and components requiring reliable internal ACME threads, this Carmex thread mill is built to deliver durable performance and predictable outcomes.
