Corded hammer drills spin their bits and vibrate them at high speed and low impact to drill small-diameter holes in asphalt, brick, cinder block, tile, and light concrete. This hammer-and-rotate action cuts holes in masonry more cleanly and easily than drilling alone. Also known as hammer drill drivers, they have a rotate-only mode to drill wood, metal, plastic, and other non-concrete materials. They are used in applications that require more power than a standard drill but don't require the large-diameter bits and heavy impact of rotary or demolition hammers. These corded hammer drills allow long run times for repetitive tasks, maintain full power during operation, and have no batteries to recharge.
