Keo 907-000-165 Combo Drill Countersink Size 6 Hss

Product Description

The KEO 907-000-165 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single pass. Built from high-speed steel with a bright uncoated finish, this tool features a 1/2-inch body diameter, a 7/32-inch drill point diameter, and a drill point angle of 118 degrees with an included countersink angle of 82 degrees. The right-hand, plain cutting edge style makes it suitable for use in standard drill presses and CNC machines. At 5 inches overall length, this is a long-length tool suited for applications where standard-length tools fall short. Machinists and fabricators working with ferrous and non-ferrous materials will find this a reliable production tool.

This combo drill countersink is intended for countersinking applications requiring a Trade Size 6 profile. The double-end design extends service life by providing two usable cutting ends before the tool is retired. It is well suited to production environments, job shops, and maintenance operations where countersunk fastener holes must be prepared quickly and accurately. The plain cutting edge style keeps chip clearance predictable in through-hole and blind-hole work alike.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Secure the tool firmly in a properly rated chuck or collet before operation and confirm spindle speed is appropriate for the workpiece material and tool diameter. Inspect both cutting ends for wear or chipping before each use. Follow applicable shop safety standards and machine manufacturer guidelines throughout operation.
