CS Unitec's annular cutters and carbide-tipped hole saws produce holes 3x faster than twist drills and leave clean, burr-free holes. Flutes run the length of the cutter for efficient chip clearance, less chatter, decreased cutter breakage and increased drilling productivity without pre-drilling or step-drilling. Annular cutters are available in hardened High-Speed Tool Steel, Titanium Aluminum Nitride (TiAlN), Tungsten Carbide, Carbide and Cobalt.
Our annular cutters have a 3/4" Weldon shank that fits most common magnetic drills, including Hougen™, Jancy™, Evolution™, Fein™ and Milwaukee™. Center Pilot Pins are included with all cutters. ID (Stacked) Geometry available.
Faster core drilling, in metal, in every situation.
