SPM65 Tungsten Carbide DTH Drill Bit 66mm Diameter Rock Drilling Tool
Product Information SPM65 Tungsten Carbide DTH Drill Bit:
Matching for SPM65 down-the-hole hammer.
DTH hammer is a part of down hole drilling rig, which is a working device of down hole drilling rig. Submersible hole impactor is divided into low air pressure submersible hole impactor, medium air pressure submersible hole impactor and high air pressure submersible hole impactor.
Applications SPM65 Tungsten Carbide DTH Drill Bit:
• Surface drilling
• Quarry benching operations
Advantages SPM65 Tungsten Carbide DTH Drill Bit:
• High drilling efficiency, long drilling tool life, submersible
impactor drilling, the medium is air, no flushing media recovery
and disposal problems, reducing the auxiliary time.
• Low cost of use, the submersible impactor requires small shaft
pressure and low speed of the drilling rig, while the torque is
low, so the natural power consumption is small, and the diameter of
the drill pipe is relatively thin, easy to install and disassemble,
and the service life is long.
