Titan Usa CS37001 Combo Drill Countersink Cobalt Altin

Product Description

The TITAN USA CS37001 is a combination drill and countersink designed to drill a pilot hole and chamfer a countersink in a single pass. Built from cobalt tool steel with an AlTiN (aluminum titanium nitride) coating, it handles demanding materials including stainless steel, hardened alloys, and high-temperature metals. The body diameter is 1/8 inch with a drill point diameter of 0.0469 inches. Overall length is 1-1/4 inches. The 118-degree drill point angle and 60-degree included angle on the countersink are standard geometry for machine screw and fastener prep work. This tool is used by machinists, tool-and-die workers, and precision fabricators on manual and CNC machine tools.

The CS37001 carries Trade Size No. 1 and is suited for countersinking small fastener holes in ferrous and non-ferrous materials. The double-end type design and right-hand cutting direction make it compatible with standard drill press, lathe, and machining center spindles. The plain cutting edge style provides clean entry and a consistent chamfer finish. Typical applications include screw-hole prep in metal fabrication, aerospace component work, and precision assembly where a flush or countersunk fastener seating is required.

Key Features

• Cobalt tool steel construction for heat resistance and durability in hard materials
• AlTiN coating reduces friction and extends tool life in high-speed and dry-cutting applications
• Combines pilot drilling and countersinking in one operation, reducing setups
• 118-degree drill point angle for standard fastener hole geometry
• 60-degree included angle matches common machine screw countersink requirements
• Double-end type with right-hand cut for use in standard rotating spindles

Compatibility

Designed as an OEM-style replacement and standard tooling option for drill presses, lathes, and CNC machining centers accepting 1/8 inch shank combination drill countersink tooling in Trade Size No. 1.

Installation Notes

Installation is performed by qualified machinists or tool-and-die professionals. Secure the tool in a proper collet or drill chuck rated for the shank diameter before operation. Ensure the machine spindle is fully stopped before changing or inspecting tooling. Use appropriate cutting fluid or dry-cut technique as indicated by the workpiece material and machine parameters.
