＼ Features of FS06 ／ ◆ Excellent Wear Resistance With a hardness of 95.0HRA, the wear at the cutting edge is suppressed compared to conventional ultra-fine carbide, leading to an expected longer lifespan. ◆ Reduced Burrs and Edge Chipping Due to its excellent wear resistance even after prolonged use, the tool shape is maintained for a long time, allowing for a reduction in burrs and edge chipping, making it suitable for precision molding tools. ◆ High Strength As the bonding phase is reduced to increase hardness in carbide, the fracture resistance typically decreases. However, FS06 maintains a fracture resistance of 4000MPa, covering strength levels comparable to conventional ultra-fine carbide despite its very high hardness. ◆ Excellent Edge Sharpness Due to the nano-sized WC alloy, a superior sharp edge can be achieved on the tool cutting edge through grinding and finishing processes of #1000 or higher.
