    BR2 76mm Hammer Bits Water Hole Deep Drilling DTH Drill Bits


    Description

    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.


    The main features are as following:

    1. Simple design of the piston. Long life span.

    2. More efficient energy transfer, faster drilling speed, low air consumption and lower oil consumption.

    3. Fewer internal parts, simple structure, long life span, less failure and easier to maintain because all the parts are heat treated.

    4. Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multiple steps thread.
