Keo 906-000-087 Combo Drill Countersink No 2 Hss Tin

Product Description

The KEO 906-000-087 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single pass. Built from high-speed steel with a titanium nitride coating, it delivers extended tool life in production and job-site environments. The body diameter is 3/16 inches, the drill point diameter is 5/64 inches, and the overall length is 1-7/8 inches. The 82-degree included angle produces a clean countersink seat, while the 118-degree drill point angle provides accurate starting without walking. Machinists, fabricators, and trade professionals use this tool for preparing fastener seats in metal, wood, and composite materials.

This tool is suited for bench drill presses, CNC machining centers, and hand-held power drills in both shop and field applications. The No. 2 trade size positions it for light-duty countersinking work, such as preparing holes for flat-head machine screws and sheet metal fasteners. The double-end design allows the tool to be flipped and reused once one end dulls, extending service life. Right-hand cutting direction is standard for conventional drill press and power tool use.

Installation Notes

Installation and use of this tool should be performed by machinists or qualified tradespeople familiar with rotary cutting tools. Secure the shank firmly in the drill chuck and ensure the workpiece is clamped before starting the cut. Always wear appropriate eye protection and follow applicable shop safety procedures. Do not exceed the drill press or spindle speed recommended for the workpiece material and tool diameter.
