Product Details

Premium material applicable for efficient cutting and precision grinding.

CN-2 adopts angular grain shape. Relatively low roundness helps reduce grinding resistance and achieve reliable cutting capacity. Reasonably matched grain toughness keeps intact cutting edges and lowers particle breakage during operation.Stable chemical composition ensures consistent grinding characteristics. Fine hydrophilicity forms firm bonding with resin binder, reducing grain loss and securing stable service performance.
