Description

The Minnich A-4SC is a high-performance on-slab pneumatic dowel pin drill engineered for maximum productivity on large-scale concrete paving projects. Featuring four 50 lb drills mounted on a rugged 3-wheeled frame, this self-propelled unit provides the versatility of both horizontal and vertical drilling with manual height adjustment for various slab depths. Its advanced crab-steering system enhances jobsite efficiency by allowing operators to drive down the slab without the need to raise or lower the drill bed between sets, while its robust design provides the necessary power to tow its own air compressor.
