Abstract
The present invention relates to a sintered body of a carbonitride alloy with titanium as main component which has improved properties particularly when used as cutting tool material in cutting operations requiring high toughness. This has been achieved by combining a carbonitride based hard phase of specific chemical composition with an extremely solution hardened Co-based binder phase.
