Elliott Cutters
1 / 5
Dome PDC inserts consist of a multilayer structure of diamond and transition layers, significantly improving impact resistance. This makes them the best alternative for roller cone applications.
Applicable Bit Position:Priority for rear row teeth, auxiliary for main teeth (soft to medium-hard broken formations). It buffers impact, protects main teeth, and prevents gravel damage.
Flat and smooth tooth surface with a 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. Crushes formation rocks quickly; as rear row teeth, it assists cutting and plays a gauge protection role.
Sharp tapered tooth tip with extremely strong penetration, reducing drilling resistance in medium-hard to hard formations. Disperses stress effectively with excellent impact toughness.
Applicable Bit Position:Exclusively for main teeth. Its core advantage is sharp penetration for hard formation crushing.
