Minnich A-1C/A-2C

Minnich A-1C and A-2C drills with steering feature on-slab drilling solutions for almost any project. The A-1C single-drill series and A-2C double-drill series can drill in horizontal, vertical and 35-degree stitch positions, and the A-1C is capable of skew drilling for maximum versatility. All models feature steering to enhance operator accuracy and control, an automatic shut-off feature that extends drill life and available dust collection to minimize dust and debris on the job site. The A-2C drill cuts operating time roughly in half due to the incorporation of the second drill.
