Carmex Thread Mills Carbide — Single Point, Metric internal thread mill designed for precision M4 x 0.7 threads. Built for tight bores and demanding applications, this MT11-based tool delivers consistent, reliable threading in metalworking environments.

• Thread milling type: Full-profile, single-point internal thread mill for accurate, repeatable threads
• Size / pitch: Metric M4 x 0.7
• Material: Carbide for stiffness, wear resistance, and long tool life
• Flute configuration: Multi-flute design (3–4 flutes) for balanced cutting action and efficient chip evacuation
• Coating: Triple blue PVD coating to reduce wear and friction during cutting
• MT interface: MT11 shank/interface for compatibility with MT toolholders
• Grade: MT11 Ultra-fine sub-micron grade for tight tolerances and superior surface finish
• Thread depth capability: Depths up to 3.5x the thread diameter, depending on profile
• Internal thread compatibility: Supports ISO metric M1 x 0.25 and 0-80 UNF threading options

This tool is ideal for producing clean, precise internal threads in small diameters where bore space is limited. The combination of carbide durability, MT11 grade precision, and a coating designed for tough materials helps minimize tool wear and maintain consistent thread quality across production runs. The 3–4 flute configuration aids in efficient material removal and smooth finishing, while the ability to target a range of standard threads (M1 x 0.25, 0-80 UNF) adds versatility to your machining toolkit. Perfect for high-precision assemblies in automotive, electronics housings, and compact mechanical components.
