The JCB PDC Cutters for Mining are sintered from diamond Micro-powder and carbide substrates under ultra-high temperature and pressure conditions. These composite sheets exhibit high wear resistance and impact resistance, while the bonding method between the diamond layer and carbide interface has been improved to optimize stress distribution, resulting in a stronger bond and significantly enhanced product reliability and service life. They offer high cost-effectiveness. JCB PDC composite sheets for coal fields and mining are widely used in geological exploration, coal field drilling, mining drilling, and foundation drilling. JCB offers PDC composite sheet products in standard specifications such as 08, 09, 10, 13, 16, 19, as well as various custom specifications.
