Carmex Thread Mills Solid Carbide - Fast Type - For Hard Materials - Metric - M2.5 x 0.45 - MT3

Carmex MT3 Solid Carbide Thread Mills, Fast Type, are precision tools engineered for hard-material threading. The M2.5 x 0.45 metric threading size and MT3 shank make them ideal for production environments that demand reliable, repeatable internal threads in tough metals.

• Thread Size & Shank: Metric M2.5 x 0.45 thread profile with MT3 solid carbide shank for compatibility with common CNC setups
• Threading Type: Fast Type geometry designed to optimize thread cutting efficiency and reduce cycle times
• Flute Count: High-flute-count design (FSH family) to improve rigidity and chip evacuation in hard materials
• Coating & Grade: Ultra-fine MT3 grade with a multi-layer PVD coating for enhanced heat resistance and wear protection
• Material: Solid carbide for exceptional stiffness and long tool life when machining hard metals
• Hardness Range: Suitable for workpieces up to 65 HRC, including challenging superalloys
• Performance: Stable cutting edge and high heat resistance maintain thread accuracy and surface finish even at higher speeds

This tool excels in producing precise, clean threads in hardened components—useful for automotive housings, mold bases, aerospace fasteners, and other hard-material assemblies. The combination of a durable coating, a multi-flute design, and a robust MT3 shank translates into dependable tool life, consistent thread quality, and efficient production cycles without sacrificing accuracy.
