Concrete Penetrating Co.
- Company Overview: nytime you need to put a hole through concrete, masonry or solid rock, you will want to call on a drilling specialist. He will very likely use one or more diamond core bits, mounted on a drilling rig or a multi-drill, gang-drilling machine. Typical applications include walls, pavement, tunnels, bridge parapets, ceilings, roofs, mine facings, roadside rock shapes, and so on.
Often the holes are made to route cables, conduit, pipes, wires, or other "thru the structure" components. Other times the holes are made to anchor bolts or lifting rods. Still, other times the holes are made simply to place explosive charges. Sometimes to install load-carrying devices, like dowel bars. There are probably thousands of reasons for making holes in concrete. Whatever the reason, the holes are normally made with the core bit.
Core bits consist of the bit tube, which has diamond segments or a full crown brazed or welded on the drilling end.
Bit sizes range from 1" diameter to 48" diameter. The bits are mounted on the rotating shaft of various types of drilling machines. Some are large drilling columns, some are track mounted, some are mounted in groups on specialized, multi-hole drill rigs, and some are even hand held drills.
The applications highlighted in the photos are representative of the many different types of holes drilled every day by members of CSDA.
