Core Features: Dome PDC inserts consist of a multilayer structure of diamond and transition layer, improving impact resistance greatly. This makes dome PDC inserts the best alternative to be applied in roller cone bits.

Applicable Bit Position: Priority for rear row teeth, auxiliary for main teeth (in soft to medium-hard formations). It buffers impact, protects main teeth, and prevents gravel damage.

Core Features: Flat and smooth tooth surface with large contact area, delivering high cutting efficiency and outstanding wear resistance. Uniform force distribution avoids local wear with high processing precision.

Applicable Bit Position: Priority for main teeth, also available for rear row teeth. It crushes formation rocks quickly and assists in gauge protection to extend bit life.

Core Features: Sharp tapered tooth tip with extremely strong penetration, reducing drilling resistance in medium-hard to hard formations. The structure disperses stress effectively with excellent impact toughness.

Applicable Bit Position: Exclusively for main teeth. Its core advantage is sharp penetration; not recommended for rear row teeth due to the small contact area.
