Cleveland C46275 Combo Drill Countersink Size 14 Hss

Product Description

The CLEVELAND C46275 is a combination drill and countersink designed to perform two operations in a single pass: drilling a pilot hole and forming a countersink recess simultaneously. Machined from high-speed steel with a bright, uncoated finish, this tool features a 5/16 inch body diameter, a 7/64 inch drill point diameter, and a 118-degree drill point angle. The bell-style cutting edge and 60-degree included angle produce a clean, consistent countersink profile suited for fastener seating in metal fabrication and general machining work. It is sized as a trade size 14 and runs with a right-hand cut.

This combo drill countersink is intended for use in metal cutting applications including alloy tool steel, aluminum, carbon steel, and cast iron. The double-end design extends tool life by providing two usable ends. It fits standard drill press, lathe, or CNC setups where countersinking and pilot drilling are performed in production or maintenance environments. Machinists, tool-and-die workers, and maintenance technicians are the typical end users.

Compatibility

Designed for countersinking and drilling applications in alloy tool steel, aluminum, carbon steel, and cast iron workpieces. Compatible with standard drill press, lathe, and CNC machine tool holders that accept a 5/16 inch shank.

Installation Notes

Install this tool in a drill press, lathe, or CNC spindle using a collet or chuck appropriate for the 5/16 inch body diameter. Secure the workpiece firmly before operation to prevent movement during cutting. Apply appropriate cutting fluid or coolant when machining steel or cast iron to extend tool life and improve finish quality. Inspect both cutting ends before use and replace the tool if chipping or excessive wear is observed.
