Description
Carmex FSH Thread Mills are an advanced solid carbide threading solution designed for hard materials. This Fast Type tool, with MT3 shank, is engineered to deliver reliable 1/4"-28 threads across UNC, UNF, UNEF, and UNS forms, making it a go-to choice for demanding metalworking applications.
- Nominal Diameter: 1/4" (0.250"), producing precise 1/4"-28 threads
- Thread Form Compatibility: Compatible with UNC, UNF, UNEF, and UNS thread forms for unified threaded components
- Shank: MT3 solid carbide shank for strong, rigid tool engagement
- Flute Count: Up to 7 flutes on select models to enhance cutting efficiency and chip evacuation in hard materials
- Material & Coating: Ultra-fine MT3 carbide with a multi-layer PVD coating designed for high heat and wear resistance
- Hardness Capability: Suitable for machining hard materials up to 65 HRC, enabling robust performance on tough alloys
- Design Advantage: Optimized edge stability and cutting efficiency of the FSH family, an evolution from the MTSH line
These thread mills are purpose-built for reliability in challenging workpieces. The combination of solid carbide, MT3 shank, enhanced flute design, and PVD coating translates to stable cuts, longer tool life, and consistent thread quality in hard materials. Whether threading through hardened steels or demanding alloy components, the FSH fast-type geometry helps maintain precision and surface finish across production runs.
