Rather than drilling out the metal with a solid drill, Drillco cutters remove only the periphery of the hole, ejecting a slug at the end of the cut.Broach cutting using Drillco cutters means you can produce large diameter holes efficiently and quickly with less energy, faster penetration and less thrust..

These ultra-hard teeth increase performance and tool life. The 9500CT is ideal for thinner material up to 3/16" thick such as sheet metal, steel, aluminum, copper, plastics, cast iron, and the difficult to machine stainless steel. Diameters 9/16" to 2.
This increases hardness (Rc 75-80) without increasing brittleness, which is measurably harder than high speed steel. The Nitro Heavy-Duty Construction Reamers have a Ferritic Nitro Carburizing surface treatment, which gives a hard, protective layer to the reamer..
