Titan Usa CS10010 Combo Drill Countersink Size 0 Hss

Product Description

The TITAN USA CS10010 is a combination drill and countersink designed to drill a pilot hole and create a countersunk seat in a single operation. Built from high-speed steel with a bright, uncoated finish, it handles common fastener prep work in metal, wood, and plastic. The body measures 0.125 inches in diameter with an overall length of 1.25 inches. A 118-degree drill point angle and 60-degree included angle on the countersink make it well-suited for standard flat-head fastener seating. The double-end configuration and plain cutting edge style deliver consistent, repeatable results. It cuts right-hand, matching standard drill press and hand-drill operation. This tool is sold as a single unit.

This combo drill countersink is used in production, maintenance, and repair applications where flat-head screws or rivets need a properly seated countersink. Trade size 0 with a 0.0313-inch drill point diameter makes it appropriate for small-fastener work in sheet metal fabrication, light assembly, and general machining tasks. Machinists, millwrights, maintenance techs, and tool-and-die workers commonly reach for this size when prepping holes for No. 0 flat-head fasteners.

Installation Notes

This tool is installed in a standard drill chuck — ensure the chuck is tightened securely before operation and the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or lubricant when working in steel to extend tool life and improve hole quality. Inspect the cutting edges before use and do not operate a chipped or dull countersink, as it can produce inconsistent seat angles and damage fastener heads.
