We drill holes ranging from 3/8" to 42" in diameter. We have both electric and hydraulic core drills. We drill cores into concrete for new conduits, plumbing, man holes, hand rails, and more. Our drills can drill as deep as needed.
Hydraulic drills are used specifically for larger diameter holes that require more power.
Electric drills are used for 12 inch and smaller sized holes. We have multiple sized electric drills. We even have smaller drills to fit into compact areas.
