The gauge bar is a polycrystalline gauge, which is a known technology in the field and aims to gauge the drill bit and prolong the service life of the drill bit. For example: by adopting the reinforced polycrystalline gauge with the diameter of 2 multiplied by 4mm, the inner diameter and the outer diameter of the diamond drill bit can be better protected, and the drill bit is prevented from being scrapped in advance due to the consumption of the inner diameter and the outer diameter in the footage.
