Cleveland C46261 Combo Drill Countersink Size 00 Hss

Product Description

The CLEVELAND C46261 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single operation. Built from high-speed steel (HSS) with a bright, uncoated finish, this Size 00 tool features a 0.025-inch drill point diameter and a 118-degree drill point angle. The 60-degree included countersink angle is standard for most countersunk fastener applications. At 1.125 inches overall length with a 1/8-inch body diameter, the C46261 is compact and suited for precise work in tight clearances. It is a right-hand cut tool with a plain cutting edge and double end type.

This combo drill countersink is used in metalworking and fabrication applications where a countersunk hole must be drilled and chamfered in one pass. Suitable workpiece materials include alloy tool steel, aluminum, carbon steel, and cast iron. It fits both production and maintenance environments and is a common choice for machinists, tool-and-die workers, and industrial maintenance technicians working with countersunk screws and rivets.
