Cleveland C46267 Combo Drill Countersink Size 5 Hss

Product Description

The CLEVELAND C46267 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single operation. Built from high-speed steel with a bright uncoated finish, this tool features a 7/16-inch body diameter, a 3/16-inch drill point diameter, and a 118-degree drill point angle. The 60-degree included angle produces a standard countersink profile suitable for flat-head fastener seating. At 2-3/4 inches overall length, it fits standard drill chucks and milling machine setups. It is sized as Trade Size 5 and cuts in a right-hand direction with a plain cutting edge style.

This combo drill countersink is suited for production and maintenance work across metalworking trades. It handles alloy tool steel, aluminum, carbon steel, and cast iron. The double-end configuration extends tool life by providing two usable cutting ends. It is commonly used in machine shops, fabrication facilities, and industrial maintenance settings where countersinking and pilot drilling must be performed efficiently in a single step.

Installation Notes

Installation is performed by machinists or tooling technicians using standard drill chucks or collet holders rated for the 7/16-inch body diameter. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Verify chuck runout is within acceptable limits to prevent premature wear on the cutting edges. Follow applicable shop safety protocols and machine manufacturer guidelines for speed and feed settings based on workpiece material.
