Keo 907-000-093 Combo Drill Countersink Size 3 Hss

Product Description

The KEO 907-000-093 is a combination drill and countersink tool machined from high-speed steel with a bright, uncoated finish. It features a 1/4-inch body diameter, a 7/64-inch drill point diameter, and a 118-degree drill point angle with a 60-degree included angle for the countersink profile. At 5 inches overall length, this is a long-length tool suited for reaching into deeper setups or fixtures. Right-hand cutting direction with a plain cutting edge style makes it compatible with standard drill press and CNC spindle setups. Installed by machinists, tool and die technicians, and maintenance trades requiring combined drilling and countersinking in a single pass.

This combo drill countersink is a trade size 3 tool intended for countersinking operations in metalworking applications. The double-end design extends tool life by providing two usable ends. The plain cutting edge style suits general-purpose countersinking in steel, aluminum, and similar materials. It is not an aircraft-style tool and is not tapered, making it appropriate for standard countersink profiles in production, maintenance, and repair environments. The UNSPSC classification 23241603 confirms its category as a combination drill and countersink cutting tool.

Installation Notes

This tool is installed and operated by machinists and maintenance technicians using standard drill press, lathe, or CNC equipment. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Secure the tool firmly in the chuck or collet to the appropriate holding specification for the machine in use. Always verify workpiece fixturing before beginning the combined drill and countersink operation to prevent tool deflection or breakage.
