Drill small-diameter holes in asphalt, brick, cinder block, tile, and light concrete with cordless hammer drills that spin and vibrate their bits at fast speed and little impact. This hammer-and-rotate technique neatly and readily makes holes in masonry than drilling alone. They're also known as hammer drill drivers, and they can drill wood, metal, plastic, and other non-concrete materials in a rotate-only mode. They're utilized in situations where you need more power than a conventional drill but don't need the large-diameter bits or high impact of a rotary or demolition hammer. These cordless hammer drills work in situations where wired power is unavailable, eliminate the tripping hazard of a cord, and are powered by brand-specific batteries.
