The anchor drill bit is divided into a cemented carbide anchor bit and a diamond compact anchor drill bit. The
1, carbide drill bit
The two-wing working part of the bolt drill bit adopts cemented carbide as the cutting tooth, which is mainly used for softer ground and the alloy has a lower manufacturing cost, and now occupies an important position in the market.
2. Diamond composite drill bit
The two wings of the anchor drill bit adopt diamond composite pieces as cutting teeth, and the application of the diamond composite piece greatly improves the drilling efficiency of the anchor bit and is gradually replacing the cemented carbide anchor bit.
