Countersinking milling cutter

solidanglewith cylindrical shank

Used for chamfering and countersinking holes, countersinks are conical cutting tools, usually featuring one or more flutes with specific angle cutting edges. The countersink may have a straight shank, tapered shank, bit stock shank or special shank requiring a special holder for, for example, holding in a power or hand operated machine. Dormer’s solid carbide countersink model G405 features an enhanced cutting geometry. It was developed to maximize the use of the carbide substrate to ensure high performance, as well as high productivity. Since the model is double-ended, it has three cutting edges on both ends of the tool, thus extending its service life.
