Cleveland C46268 Combo Drill Countersink Size 6 Hss

Product Description

The CLEVELAND C46268 is a combination drill and countersink designed to perform spot drilling and countersinking in a single operation. Built from high-speed steel with a bright, uncoated finish, this tool features a 0.5-inch body diameter, a 7/32-inch drill point diameter, and a 60-degree included angle that produces clean, accurate countersinks. The 118-degree drill point angle and plain cutting edge style make it well suited for right-hand cutting on a variety of ferrous and non-ferrous materials. It is a standard choice for machinists, fabricators, and maintenance technicians working with drill presses, lathes, or CNC machining centers.

This combo drill countersink is designed for use in metal fabrication shops, maintenance and repair operations, and production environments where efficient hole preparation is required. It performs countersinking and drilling simultaneously on alloy tool steel, aluminum, carbon steel, and cast iron workpieces. The double-end style maximizes tool life by providing two usable ends, extending service intervals in high-use applications.
