The Carmex Thread Mills Carbide—Single Point, Metric (M2 x 0.4) with MT11 shank is a precision internal-threading tool designed for CNC mills. Built for reliable, tight-tolerance metric threads, it combines advanced carbide grade with a tough blue-coated finish to deliver consistent performance in challenging bores.

• Tool Type: Full-profile, single-point thread mill for internal threading
• Thread Size: Metric M2 x 0.4 capability for compact, high-precision threads
• Flute Count: 3–4 flutes for strong cutting action and efficient chip evacuation
• Material & Coating: MT11 ultra-fine sub-micron carbide with triple blue PVD coating
• Thread Depth Potential: Depths up to 3.5 × the thread diameter, depending on profile
• Small-Thread Capability: Supports very small threads including ISO M1 x 0.25 and 0-80 UNF
• Interface: MT11 shank compatible with common milling centers and tool holders

Designed to deliver clean, accurate internal threads with reliable surface finish, this thread mill excels in tight bores and challenging materials. The carbide MT11 grade provides wear resistance for longer tool life, while the triple blue PVD coating helps reduce heat and built-up edge during cutting. The 3–4 flute geometry enhances stability and chip evacuation, enabling deeper thread cuts in fewer passes. Ideal for production environments and job shops, it supports a range of metric internal threads in compact components such as housings, connectors, and fastened assemblies where precise threading is critical.
