Kyocera has launched of its 2KMB solid-carbide ball-nose end mill for high-hardness material processing and micro-machining. Used in the fine machining of precision parts and metallic moulds, this new solid-carbide round tool product is now available globally from Kyocera.

2KMB is the second product launch in Kyocera’s K-series solid-carbide line, which combines new coating technology with a proprietary shape for the effective micro-machining of various high-hardness materials such as alloy tool steel, stainless steel and high-speed steel (HSS).

Kyocera’s new wear-resistant coating, MegaCoat Hard Ex, features a special two-layer structure to ensure stable processing with high toughness and chipping resistance. The wear resistance and chipping resistance both contribute to higher quality and longer tool life. According to Kyocera, the coating facilitates long tool-life processing due to its superior oxidation resistance and wear resistance. Notably, the coating supports quenched hardened steel processing from tempered steel up to 70 HRc.

The newly developed S-shaped cutting edge with high levels of sharpness deliver a high-quality surface finish on the component and maintain wear resistance. Here, a wide core thickness increases tool rigidity, which prevents collapse and ensures stable processing. As another stand-out feature, point cutting (strong back taper) reduces collapse and prevents chattering, while the novel cutting edge shape gradually changes rake angle and clearance angle, compatible with high blade edge strength and low resistance.
