Annular cutter bits

Annular cutter bits are generally used in magnetic drills.  These drills vary in size, weight and their horsepower, thereby affecting the hole diameter they can drill. They are mostly used in structural steel but are also used in applications such as drilling truck frame rails, steel signage, guard rails, sheet metal and plate materials.

Magetic  drills normally use annular cutters as opposed to solid drill bits. These are hollow cutters, so only the outer perimeter of the drill is in contact with the steel, thereby significantly reducing the horsepower needed to drill a given diameter.
