Carmex FSH Thread Mills are fast-type, solid carbide tools designed to deliver reliable, precise threads in hard materials. Built for professionals who demand consistent performance in demanding alloys, these mills elevate thread-making with a focus on stability and endurance.

• Thread size: 1/4"-20 UNC/UNF/UNEF/UNS with MT3 shank
• Fast Type design: optimized geometry for rapid material removal and stable cutting in tough materials
• Flute count: up to 7 flutes on select models to improve chip evacuation and finish quality
• Material and grade: solid carbide MT3 with ultra-fine grade for exceptional edge stability
• Coating: multi-layer PVD coating for high heat resistance and reduced wear in hard alloys
• Hard-material capability: engineered to cut hard materials up to 65 HRC and to machine superalloys

These thread mills are designed to deliver precise thread profiles with extended tool life, making them a dependable choice for aerospace, automotive, and precision engineering applications. The MT3 shank paired with a PVD coating supports high-temperature milling environments, while the 1/4-20 thread standard covers common fastener applications. Whether working with hardened stainless steels, nickel-based alloys, or other hard materials, Carmex FSH thread mills provide consistent performance and repeatable results.
