1. Optimized interface between diamond and tungsten carbide layers for excellent binding. 

2. Penetration rate is improved by using high quality diamond powder which is self-sharpening. 

3. Cutters can drill a precise round hole and reduce bit whirl as its force balanced design. 

4. Gauge pads use tungsten carbide inserts for maximum wear resistance. 

5. The diamond layer with thickness over 1 mm increases abrsion resistence of PDC cutter. 

6. Good thermal stability.
