When the drill bit meets big rocks during drilling into the stratum, the helmet surface of GK helps to crush the rocks or squeeze them into the fissure, so that the cutting surface of GK is protected and its service life is prolonged.
The three performance:
(1)impact resistance
It can stand the impact more than **0 times, but the common PDC can only have *0 times of impact.
(2)wear resistance
The abrasion ressistance of GK is highly improved by using the
superfined diamond powder and adding some special activated
elements and adopting special technology of synthesis. Its wear
ratio is up to **0,**0 which is twice as the common PDC.
(3)Thermal stability
GK is made by using the special helmet design, so that the stress
on the surface of GK will be eliminated and dispersed. There is a
special layer called “transition layer” which helpd to improve the
thermal stability and bond strength of this product.
