Keo 907-000-183 Combo Drill Countersink Size 8 Hss

Product Description

The KEO 907-000-183 is a combination drill and countersink designed to drill a pilot hole and form a countersink recess in a single pass. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable performance across standard metalworking and fabrication applications. The tool features a 3/4 inch body diameter, a 5/16 inch drill point diameter, a 118-degree drill point angle, and a 90-degree included angle for countersinking. At 6 inches in overall length, it qualifies as a long-length tool and is suited for applications requiring extended reach. Right-hand cutting direction and a plain cutting edge style make it compatible with conventional drill press and CNC setups.

This combo drill countersink is intended for trade professionals and machinists working in metal fabrication, maintenance, and repair environments. The Size 8 trade designation and 3/4 inch body diameter suit it for medium-duty countersinking tasks where a screw head or fastener seat must be precisely formed. The double-end configuration extends tool life by providing two usable ends. It is not aircraft style and is not tapered, making it a straightforward general-purpose countersinking tool for shop and field use.
