Titan Usa CS50044 Combo Drill Countersink Size 4 5/16 in Hss

Product Description

The TITAN USA CS50044 is a combination drill and countersink designed for creating pilot holes and countersink profiles in a single pass. Built from high-speed steel with a bright uncoated finish, this tool handles drilling and chamfering operations on metal, wood, and composite materials. The 5/16-inch body diameter pairs with a 1/8-inch drill point to produce clean, consistent countersink seats. At 4 inches overall length, it fits standard drill press chucks and hand drills. The 60-degree included angle and 118-degree drill point angle are suited to common fastener countersink geometries. Machinists, fabricators, and general maintenance trades install this tool in production and repair workflows.

This combo drill countersink is used in light fabrication, sheet metal work, woodworking, and general maintenance applications where a countersunk seat is needed for flathead fasteners. The double-end type and right-hand cutting direction make it compatible with standard rotating drill equipment. It is well-suited to bench drilling, CNC, and hand-drill operations at low to moderate feed rates across a variety of workpiece materials.

Compatibility

Designed as a standard-style combination drill countersink for use with conventional drill presses, CNC equipment, and hand drills accepting a 5/16-inch body diameter tool.

Installation Notes

This tool is typically installed by machinists or maintenance technicians using a drill press, mill, or hand drill. Secure the tool firmly in the chuck before operation and confirm the workpiece is clamped to prevent movement. Use appropriate cutting fluid when drilling harder metals to extend tool life. Inspect the cutting edges before each use and replace the tool if chipping or wear is observed.
