Document Type and Number:
Japanese Patent JP7216915
Kind Code:
B2
Abstract:
To provide a diamond-coated cemented carbide tool which suppresses chipping, defects, detachment and the like, even in high-speed and high-feed cutting work of a hard-to-cut material, such as CFRP/AI materials applying a high load to a cutting edge, and which exhibits excellent wear resistance over a long period of use.SOLUTION: In a diamond-coated cemented carbide tool, a tool substrate is coated with a diamond film. The tool substrate comprises a hard layer containing WC and a binder phase containing Co, and is made of a composition containing 72.4-93.6 mass% of WC, 4.0-12.0 mass% of Co, 2.4-15.6 mass% of Cr, 1.0 mass% or less of a grain growth inhibitor, and the balance of inevitable impurities.SELECTED DRAWING: None
