DTH Drill Bit
DTH bit is the tool cutting rocks, and subject to severe stress from the striking piston as well as from the abrasive cuttings passing the bit at high velocity. When selecting the right bit for optimum performance you have to balance penetration against bit life. On occasion you can successfully sacrifice bit life for penetration, remember the rule of thumb that states that a 10% increase in penetration covers at least a 20% loss in bit life.
We can design and manufacture the personalized products to meet your specical apllication, such as changing the tungsten carbide insert profile (spherical, ballistic, etc.), face profile (flat face, concave, convex, etc.), and flushing holes.
