Elliott Cutters
1 / 5
Dome PDC inserts consist of a multilayer structure of diamond and transition layers, significantly improving impact resistance. This makes dome PDC inserts the best alternative for roller cone applications.
Priority for rear row teeth, auxiliary for main teeth in 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.
Priority for main teeth. It crushes rocks quickly with high efficiency. Also available for rear row teeth to assist cutting and provide gauge protection.
Sharp tapered tip with extremely strong penetration, reducing drilling resistance in medium-hard to hard formations. Disperses stress effectively with excellent impact toughness to avoid chipping.
Exclusively for main teeth. Its core advantage is sharp penetration for hard formation crushing. Not recommended for rear row teeth due to potential uneven force damage.
