DTH bit and tricone bit are two kinds of core rock breaking tools in geotechnical engineering. DTH bit penetrates hard rock efficiently through impact rotation composite action, which is suitable for deep hole operation; The cone bit relies on multi bevel gears to roll and crush rock layers, and is good at large-diameter drilling in medium hard rock layers. The two complement each other in mining, infrastructure and other fields. The former is good at impact, while the latter is good at wear resistance, jointly promoting the development of modern drilling technology.

Types of Drill Bit

  • DTH Drill Bit
    Ultra-durable DTH hammer bits with tungsten carbide buttons for extreme wear resistance. Engineered for faster penetration & longer service life in mining, quarrying & construction. Compatible with most DTH hammers.
