A series (steel body)
Owing to remarkable material properties of the body, A series (steel body) have a significant speed advantage in drilling soft to medium hard formation with good homogeneity and low abrasiveness. Through thermal treatment and surface hardening process, steel body bit has better toughness than matrix body bit, which improves impact resistance of bit. Meanwhile, surface hardening process on blades and gauges reduces erosion efficiently.
