On-Grade Series
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.
Features
TRIGGER GRIPS
The A-1 Series drills feature two intelligently designed trigger grips. The first trigger facilitates the drill's movement in and out of the concrete. The second trigger activates the drilling action only when squeezed. This dual-trigger system transforms user safety, empowering operators with the ability to swiftly halt the drilling process by releasing their grip on the trigger. With this design, we prioritize not only efficiency but also the well-being of our users, making every drilling task an experience that's both productive and secure.
CUTOUT SIZES
The A-1 Series is designed to simplify your workspace dynamics. With options perfectly tailored for your needs, our drill effortlessly fits into either 36- or 48-inch cutouts while keeping its wheels intact, ensuring hassle-free repositioning. For projects demanding an even more compact footprint, the A-1 Series presents an array of drill alternatives designed to excel within 24- and 30-inch openings.
PIVOTING WHEELS
Our drill is equipped with pivoting wheels that allow the operators lateral movement within the cutout. Move side to side, ensuring precise positioning and minimizing operational strain. The wheels' alternate configuration facilitates effortless transport between cutouts, streamlining workflow and maximizing productivity.
