Cleveland C46269 Combo Drill Countersink Size 7 Hss

Product Description

The CLEVELAND C46269 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single pass. Built from high-speed steel with a bright, uncoated finish, this tool features a 5/8 inch body diameter, a 1/4 inch drill point diameter, and a 118-degree drill point angle. The 60-degree included angle produces a standard countersink profile suited to flat-head fastener seating. Right-hand cut geometry and a plain cutting edge style make this a straightforward, reliable choice for machinists and fabricators working in production or maintenance environments.

This combo drill countersink is suited for use in drill presses, CNC machining centers, and manual milling setups. It is rated for work in alloy tool steel, carbon steel, cast iron, and aluminum. The double-end type design and non-tapered shank allow direct chucking without adapters in standard setups. Typical applications include countersinking for flat-head cap screws and machine screws in metalworking, fabrication shops, and industrial maintenance operations.

Installation Notes

Installation should be performed by a qualified machinist or tooling professional. Secure the workpiece firmly before operation and confirm the spindle is fully stopped before changing or adjusting the tool. Use appropriate cutting fluid for ferrous materials to extend tool life and maintain cut quality. Always verify chuck or collet grip is secure before initiating a cut.
