TN610/TN620

Hybrid cermet

The new hybrid cermet grades are ideal for a wide variety of metal-cutting applications ranging from high-speed to low-speed machining by exceeding conventional materials in both hardness and strength through proprietary material technologies. Kyocera has drawn on its many years of cermet technology development to create these new materials, which offer improved abrasion resistance, better fracture resistance and better surface finish quality than conventional steel-cutting tools.

Uncoated cermet for high speed / continuous machining and general use.

TN610

• Higher wear resistance during continuous and finish machining.
• High quality / High precision machining
