Keo 907-000-182 Combo Drill Countersink Size 8 Hss

Product Description

The KEO 907-000-182 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single operation. Built from high-speed steel with a bright, uncoated finish, this tool features a 5/16 inch drill point diameter, a 118-degree drill point angle, and an 82-degree included angle for the countersink. The 6 inch overall length and 3/4 inch body diameter make it a long-length tool suited to applications requiring extended reach. Right-hand cutting direction and a plain cutting edge style provide clean, reliable results on a wide range of workpiece materials.

This combo drill countersink is intended for countersinking applications in metal fabrication, maintenance, and general machining environments. The size 8 trade designation matches standard fastener sizing for common countersunk-head screws. Its double end type extends tool life by providing two usable ends. The long-length design accommodates setups where standard-length tools cannot reach the workpiece. This tool is commonly used by machinists, maintenance technicians, and metalworking tradespeople working with drill presses, CNC equipment, or hand-held power drills.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or tradespeople familiar with proper drill and countersink procedures. Secure the workpiece firmly before operation and ensure the spindle speed is appropriate for the material being cut. Inspect the cutting edges before each use and discontinue use if chipping or excessive wear is observed. Follow all applicable workshop safety practices and equipment manufacturer guidelines.
