Cleveland C46265 Combo Drill Countersink 7/64 in Hss

Product Description

The CLEVELAND C46265 is a combination drill and countersink tool designed to perform two operations in a single pass: drilling a pilot hole and cutting a countersink seat. Built from high-speed steel with a bright, uncoated finish, this tool handles the demands of production and maintenance work in metal fabrication shops and light industrial environments. It features a 7/64 inch drill point diameter, a 118-degree drill point angle, and a 60-degree included countersink angle. The double-end design extends tool life by offering two usable cutting ends. A licensed machinist, toolmaker, or skilled trades professional typically operates this tool in a drill press or CNC setup.

The C46265 is suited for countersinking and pilot drilling in alloy tool steel, carbon steel, cast iron, and aluminum. It carries a trade size of No. 3 and an overall length of 2 inches (50.80 mm). The right-hand cut and plain cutting edge style make it compatible with standard drill press chucks and hand drills. Typical applications include preparing holes for flat-head fasteners, deburring, and center-spotting prior to finish drilling in both job shop and production environments.

Installation Notes

A machinist or skilled trades professional should secure the workpiece firmly before operation. Power down and de-energize the drill press or spindle before changing or inspecting the tool. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect both cutting ends for wear or chipping before each use and replace the tool if damage is found.
