Minnich’s engineering staff will create air- or hydraulic-powered dowel-pin drilling units to meet your job specifications. These drills will bore two holes 1-inch in diameter and 30 inches deep in a 6-inch-by-6-inch pattern. The unit drills two holes and then rotates 90 degrees to drill two more holes. Drills also can be designed to place rebar in concrete piles.
