Keo 906-000-086 Combo Drill Countersink Size 2 Hss

Product Description

The KEO 906-000-086 is a combination drill and countersink designed for producing a precisely centered, chamfered hole in a single operation. Built from high-speed steel with a bright, uncoated finish, this tool is sized at trade size 2 with a 3/16-inch body diameter. The 5/64-inch drill point diameter and 118-degree drill point angle create an accurate pilot before the 82-degree included angle countersink seats the fastener flush. The double-end design extends tool life by providing two usable cutting ends. Right-hand cutting direction suits standard drill press and hand drill setups. Licensed machinists, tool and die shops, and fabrication professionals install and use this tool in production and repair environments.

The 906-000-086 is suited for countersinking applications in metalworking, light fabrication, and general machining where a combined drilling and countersinking operation is preferred. With an overall length of 1-7/8 inches, the compact profile works in benchtop drill presses, CNC machining centers, and hand-held drill applications. The plain cutting edge style and non-tapered shank make it straightforward to chuck in standard drill holders. It is not rated for aircraft-style applications and is not a long-length tool.

Installation Notes

Secure the tool in a chuck or collet rated for the 3/16-inch body diameter before operation. Power down all equipment completely before changing or inspecting tooling. Verify that drill press speed is appropriate for the workpiece material and tool diameter before engaging the cut. Wear appropriate eye and hand protection per shop safety standards.
