5 Inch Carburized Steel DTH Drill Bit for Water Well Drilling and Mining Applications
The DTH bit is the primary tool for cutting rock formations, and drilling performance is directly dependent on bit quality. Down-the-hole bits endure severe stress from striking pistons and abrasive cuttings passing at high velocity. When selecting the optimal bit, balance penetration rate against service life. In certain applications, sacrificing some bit life for increased penetration can be justified—a 10% increase in penetration typically offsets at least a 20% reduction in bit life.
