Core Features: Dome PDC inserts consist of multilayer structure of diamond and transition layer, improving impact resistance greatly, making them the best alternative for roller cone applications.

Applicable Position: Priority for rear row teeth. As rear row teeth, it buffers impact, protects main teeth and prevents gravel from damaging the main cutting part.

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

Applicable Position: Priority for main teeth. It crushes formation rocks quickly; as rear row teeth, it assists cutting and plays a gauge protection role.

Core Features: Sharp tapered tip with extremely strong penetration, reducing drilling resistance in medium-hard to hard formations. Disperses stress effectively to avoid chipping.

Applicable Position: Only for main teeth. Optimized for hard formation crushing where sharp penetration is required.
