Good Quality Diamond Insert / Bit Insert for Rock Drilling with Long Wear Life

1. Product Description:

(Polycrystalline diamond compact) PDC insert consists of polycrystalline diamond layer and tungsten

carbide substrate. It combines the highest hardness, abrasion resistance of diamond and the high

shock resistance of tungsten carbide. 

Using diamond inserts in traditional rock bits can boost performance, increase durability, and

dramatically improve drilling economics. Diamond-enhanced rock bits also make it possible to

drill formations that are too difficult for traditional tungsten carbide inserts.

requirement, including ovoids, conicals, and chisels. Here below is one of these shape with full

plate,flat-top.
