The Jancy Slugger uncoated, high-speed steel annular cutter with 3/4” depth and a 1/2” annular cutter shank is used to create through holes as deep as 3/4” in a range of materials, with best performance in mild steel and structural steel. An annular cutter removes only the circumference of a through hole (extending through the workpiece), releasing the central material as a slug when the hole has been cut. The center-free design of the tool results in energy efficiency and reduced cycle time: the operator can produce holes three to five times faster than with a conventional twist drill that must convert the entire hole into chips. In addition, this tool’s multiple cutting edges can create an accurate, burr-free hole that minimizes the need for secondary operations such as pre-drilling and reaming.
High-speed steel (HSS) is a common general-purpose steel for cutting tools and is compatible with a variety of materials. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials and provides an economical alternative to coated tools.
This tool’s annular cutter shank has two Weldon flats ground into a portion of the sides to provide a secure hold to help prevent slippage in drill presses, mills, or lathes. In this Jancy tool series, annular cutters can create holes of various diameters with a depth of cut as great as 3/4”.
Annular cutters are hollow drill bits that cut only the periphery of a hole, reducing the torque and horsepower requirements for drilling in many applications. Because they remove less material than standard twist drill bits, they have faster cutting speeds and use less energy in comparison with twist drills and are more efficient than metal hole saws. The multiple cutting edges on annular cutters 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 the fabrication trade. The company, founded in 1957 and headquartered in Davenport, IA, provides tools that meet ANSI standards to steel fabricators and erectors, machinists and maintenance personnel, and truck body and ship builders, among others.
