Maximize versatility and work efficiently in tight spaces with Minnich A-1 Series single-drill, on-grade units. A-1 Series machines can be configured to drill four ways — horizontally, vertically, into a wall or six inches from a corner — eliminating the need for additional equipment or conversion kits. The A-1 Series includes models that can fit into 36- and 48-inch cutouts with their wheels on, making repositioning easy. For jobs in even closer quarters, the A-1 Series offers drill options for 24- and 30-inch openings.
