Why are bread PDC pieces more expensive than flat PDC pieces?

1. The central top of the bread PDC slice is raised, and the thickness of the bread PDC slice is thicker, which means that the diamond layer content of the bread PDC slice is more.
2.The technology and production process required for bread PDC slices is more complex and cumbersome.

Relative merits
Penetration speed: flat PDC pieces>bread PDC pieces
Wear resistance: bread PDC pieces>flat PDC pieces
Flat PDC pieces have a faster penetration speed and wear resistance is not as good as bread PDC pieces in complex formation like rubble. The impact resistance of bread PDC pieces is stronger, but the penetration is slower in the ordinary formation.

How to choose?
According to the features of the formation you need to drill, combine the advantages of the PDC to choose the right PDC composite piece.
