Carmex FSH Thread Mills are high-performance solid carbide tools engineered for precise thread milling in hard materials. With an MT3 shank and compatibility with UN, UNC, UNF, UNEF, and UNS thread standards, these fast-type mills are ideal for producing No. 6 x 32 threads in demanding applications.

• Material & construction: Solid carbide body delivers exceptional rigidity and wear resistance for sustained accuracy in hard metals.
• Coating: Ultra-fine MT3 grade with a PVD multi-layer coating, optimizing heat resistance and reducing wear when cutting superalloys and hard materials up to 65 HRC.
• Flute count: Up to 7 flutes on select models to enhance chip evacuation and maintain a stable cut in tough workpieces.
• Shank: MT3 compatibility for secure seating and repeatable alignment in standard toolholders.
• Thread compatibility: Supports UNC, UNF, UNEF, UNS and other UN family thread forms for versatile threading tasks.
• Cutting geometry: Fast-type design tailored for high-feed threading with strong edge stability and consistent thread profiles.
• Size: No. 6 x 32 thread form with precise geometry to deliver clean, accurate threads in one or few passes.

These thread mills deliver dependable performance in applications ranging from aerospace fasteners to automotive hardware and precision tooling. The combination of a robust carbide core, multi-layer coating, and high-flute geometry translates to longer tool life, tighter tolerances, and smoother thread surfaces. Ideal for production environments where repeatable quality and efficiency matter most.
