“Z” Bit – 6-3/4″ x API 2″ x 3″

SKU: WTB-Z-6630 Category:

Named for the appearance of the face, the Z bits are designed for gravel and sandy rock formations. The leading edge creates a “scooping” action while the reduced shoulder area allows gravel to fall easily past the bit reducing the possibility of being wedged against the casing. Carbide inserts fracture any hard rock encountered in these types of formations.
