Hole openers sizes thru 30" (762 mm.)

It may sometimes be necessary to drill a large hole employing a small hammer.
Hole openers are splined for all popular hammers in a wide range of sizes. Pilot diameter is 1/8" less than nominal pilot hole diameter.
Tungsten carbide buttons on the cutting face and carbide gauge buttons on the pilot face provide faster cutting.
