Carmex Thread Mills Carbide — Single Point are high-precision internal threading tools designed for miniature metric threads. Built for machinists and manufacturers who demand clean, accurate internal threads in tight spaces, these MT11-shank mills deliver reliable performance on CNC mills and multitasking centers.

• Thread sizes supported: ISO metric M1.2, M1.4, M1.6 with 0.25 mm pitch, plus 0-80 UNF internal threads.
• Profile and geometry: Full-profile, single-point design optimized for internal threading with consistent thread engagement.
• Depth capability: Capable of thread depths up to 3.5 × the thread diameter, depending on profile.
• Flute configuration: Multi-flute design (3–4 flutes) for improved rigidity, smoother cutting, and efficient chip evacuation.
• Material and coating: MT11 ultra-fine sub-micron carbide with a triple blue PVD coating for enhanced wear resistance and reduced friction.
• Shank compatibility: MT11 shank fits standard tool holders and collets used in precision milling setups.

These internal thread mills enable you to produce precise, repeatable threads in small-diameter holes—crucial for micro-fastening and compact assemblies. The combination of carbide hardness, advanced coating, and a carefully engineered flute count delivers clean thread surfaces, longer tool life, and dependable performance when tapping isn’t feasible. Ideal for miniature components in electronics, medical devices, aerospace hardware, and precision instrumentation, this Carmex line supports reliable micro-threading without compromising on accuracy or finish.
