The Minnich A-3SCW self-propelled wireless concrete dowel pin drill increases drilling efficiency, accuracy and safety on patchwork, highway and airport jobs. Wireless remote control technology enables A-3SCW operators to drill three holes at once and drive down the slab to drill the next set of holes — all while standing in the grade away from the equipment. From this clear vantage point, operators can drill faster and more accurately while avoiding dust, debris and obstacles. Power crab steering further boosts efficiency by letting operators drive down the slab without raising and lowering the drill bed. The drill can be equipped with an optional dust collection system to further increase safety and help achieve silica dust regulations.
