Elliott Cutters
1 / 5
Dome PDC inserts consist of multilayer structure of diamond and transition layer, improving impact resistance greatly, which makes dome PDC inserts the best alternative to be applied in roller cone.
Applicable Bit Position:Priority for rear row teeth, auxiliary for main teeth. It buffers impact, protects main teeth and prevents gravel damage; in medium-hard formations, it ensures drilling continuity.
Flat and smooth tooth surface with large contact area, delivering high cutting efficiency and outstanding wear resistance. Uniform force bearing avoids local wear with high cost performance.
Applicable Bit Position:Priority for main teeth. It crushes formation rocks quickly with high efficiency; as rear row teeth, it assists cutting and provides gauge protection to extend bit life.
Sharp tapered tooth tip with extremely strong penetration, reducing drilling resistance and breaking hard formations quickly. Disperses stress effectively with excellent impact toughness.
Applicable Bit Position:Only for main teeth. Its core advantage is sharp penetration for hard formation crushing; not recommended for rear row teeth due to small contact area.
