Keo 906-000-102 Combo Drill Countersink Size 3 Hss Tin

Product Description

The KEO 906-000-102 is a combination drill and countersink designed to drill a pilot hole and create a countersink seat in a single pass. Built from high-speed steel with a titanium nitride (TiN) coating, it delivers improved wear resistance and longer tool life compared to uncoated HSS. The body measures 1/4 inch in diameter with a 7/64 inch drill point diameter and a 7/64 inch drill point length. The included countersink angle is 82 degrees with a 118-degree drill point angle. At 2 inches overall length, it fits standard drill chucks on bench-top drill presses and hand drills. Machinists, pipefitters, and general fabricators use this tool when preparing holes for flat-head fasteners or deburring entry points.

This combo drill countersink is suited for use in metal fabrication shops, maintenance facilities, and light manufacturing environments. It handles countersinking operations on ferrous and non-ferrous materials where a clean, chamfered seat is required ahead of fastener installation. The right-hand cutting direction and plain cutting edge style make it compatible with standard drill press setups and handheld power drills. The double end type provides extended service before replacement is needed.
