Carmex Thread Mills Carbide – Single Point – ACME is a high-precision internal thread milling tool designed for machinists and manufacturers who need accurate, durable internal threads. Built for reliability in tight cavities and demanding materials, it delivers clean, consistent thread quality with every pass.

• Thread Milling Type: Internal, full-profile single-point milling for precise internal threads (ACME standard).
• Size & Interface: 3/4, 7/8 x 6 with MT11 interface for compatible tool holders.
• Flute Count: Multi-flute design with 3–4 flutes for stable cutting and efficient chip evacuation.
• Material & Grade: Carbide body with MT11 Ultra-fine sub-micron grade for excellent edge retention.
• Coating: Triple blue PVD coating reduces wear and lowers friction in metalworking conditions.
• Internal Thread Capabilities: Supports internal threads from ISO M1 x 0.25 to 0-80 UNF (depth dependent on profile).
• Depth Capability: Thread depth up to 3.5x the thread diameter, enabling deeper internal threads when profile allows.

This tool is optimized to produce precise, bur-free internal threads in metal parts, with smooth finishes and long tool life thanks to its advanced coating and ultra-fine carbide grade. The combination of multi-flute design and full-profile geometry improves cutting stability, reduces cycle time, and expands the range of internal thread sizes you can machine in a single setup. Ideal for ACME threads in leadscrews, hydraulic components, and precision assemblies where consistent thread quality matters.
