Guide Diameter 80- 445mm DTH Hole Opener For Water Conservancy

Product Description

Hole opener bits are designed specifically for this purpose, which is an effective way of enlarging holes, hence the bits named as "Hole Opener". A common practice involves drilling a relatively small pilot hole at first stage, and second and final stage then further widening it with a hole opener bits, since this can result in a straighter hole and require less powerful machinery. And different stages can be set per drilling specifications to maximize cutting breaking and removal, and rig capabilities. Besides, rotation torque, the DTH hole opener involves a concussive force that repeatedly impact a drilling head to the rock or other substrate. The impacting action can pulverize rock and also force it back and up, helping to clear out the borehole. So, in addition to widening a bore hole, a hole opener can also clean excess material out of it.

Applications

It is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and so on.
