Minnich A-2SC multiple-drill self-propelled with skid steering offer highly productive on-slab drilling solutions. A-2SC drills have the weight and strength to tow their own air compressor. Capable of horizontal and vertical drilling, the drills have crab steering that boosts efficiency by letting operators drive down the slab without raising and lowering the drill bed. On-grade kits, auto control and dust collection are available.
