The Jancy Slugger uncoated, high-speed steel (HSS) annular cutter set includes 11 annular cutters with 1" depth and a 3/4" shank, with one each of the following cutter diameters: 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8", 15/16", 1" and 1-1/16". The cutters create through holes as deep as 1" in a range of materials, with best performance in mild steel and structural steel. The set also includes a pilot pin for 7/16" to 1/2" cutter diameters, a pilot pin for 9/16" to 1-1/16" cutter diameters, and a case.

High-speed steel (HSS) is a general-purpose steel that offers toughness and shock resistance, and is compatible with a variety of materials. The cutters have no coating or surface treatment, and the cutting edges can be resharpened for longer tool life. Each cutter has a 3/4" shank to accommodate the 3/4" arbor of a magnetic drill or to connect to a drill press with an arbor assembly (sold separately).

Drill bits are cutting tools used to make holes in a range of materials. They are used in machines such as handheld portable drills, drill presses, machining centers, and lathes. Drill bits come in a variety of types and lengths. Annular cutters are hollow drill bits that cut only around the periphery of a hole. They reduce the torque and horsepower requirements for drilling in many applications because they remove less material than standard twist drill bits. As a result they have faster cutting speeds and use less energy in comparison with twist drills; they can also be more efficient than metal hole saws. Because of their multiple cutting edges, annular cutters can produce accurate, burr-free holes without the need for pilot holes , minimizing the need for secondary operations such as pre-drilling, step drilling, or reaming.

Jancy Engineering manufactures Slugger portable magnetic drills and annular cutters, as well as metal working equipment for fabrication. The company, founded in 1957, is headquartered in Davenport, IA.
