Abstract

The invention discloses an ultrastrong diamond compact bit belonging to rock-breaking tools, which is mainly applicable to coal-mine gas drainage holes, water detection holes, grouting holes and geological prospecting drilling holes. The ultrastrong diamond compact bit comprises a drill stem and a drill bit, wherein the drill stem and the drill bit are connected through screw threads. The bit is characterized in that the drill bit is composed of a diamond compact, a rock-breaking column, a water hole and a gauge-protection bar, wherein the drill bit is inlaid with the rock-breaking column and brazed with the diamond compact and the gauge-protection bar. The ultrastrong diamond compact bit can drill into medium hard rock stratum, and has the advantages of excellent wear resistance, strong torsion resistance, faster rock breaking speed, good cooling and scrap removal, inconspicuous gauge shrinkage phenomenon and high construction efficiency.

Description

technical field [0001] The invention belongs to a rock-breaking tool, which is mainly used in coal mine gas drainage holes, water exploration holes, grouting holes and geological exploration drilling holes, and in particular relates to a super-strong diamond composite drill bit. Background technique [0002] The existing drill bits have low wear resistance. In practical applications, the diamond composite sheet is easy to collapse, and the diameter shrinkage phenomenon is obvious during the drilling process, thereby affecting the drilling depth of a single drill bit. Contents of the invention [0003] The invention aims to provide a super-strong diamond composite drill bit with good wear resistance, high impact toughness, no obvious shrinkage phenomenon and long service life. [0004] Realize the technical scheme of the present invention: comprise drill rod, drill bit, drill bit and drill rod are connected by screw thread, it is characterized in that drill bit comprises di...
