Champion CT150STK-11/16 11/16" Carbide-Tipped Stack Annular Cutter — 1-3/8" Depth for Drilling Multiple Steel Plates
The CT150STK-11/16 is an exact 11/16" carbide-tipped stack annular cutter designed to drill through multiple layers of steel in one operation. The 1-3/8-inch depth of cut and special stack-cutting tooth geometry help maintain hole accuracy when drilling stacked plate, truck frames, and layered fabrication assemblies.
Precision-ground tungsten carbide teeth are brazed to a hardened steel body and use Champion's triple-edge cutting system for fast, clean, burr-reduced holes. Use this annular cutter with a compatible magnetic drill press, 3/4" Weldon-style arbor, CT150P pilot pin, and carbide-rated cutting lubricant.
