Keo 906-000-327 Combo Drill Countersink Metric Hss

Product Description

The KEO 906-000-327 is a combination drill and countersink designed to perform pilot drilling and countersinking in a single operation. Built from high-speed steel (HSS) with a bright, uncoated finish, this tool delivers clean, accurate results in general metalworking and fabrication applications. It features a 120-degree drill point angle, a 60-degree included angle for the countersink, and a plain cutting edge style with right-hand cutting direction. The double-end configuration extends tool life by providing two usable ends. At 0.1 pounds, it is lightweight and suited for use in standard drill presses or hand-held power tools.

This combo drill countersink is intended for metric applications requiring precise countersink geometry. It is commonly used by machinists, tool and die workers, fabricators, and maintenance technicians working with ferrous and non-ferrous metals. The 3.15 mm drill point diameter and 50.00 mm overall length make it appropriate for light to medium countersinking tasks in shop or field environments where a single-pass operation is preferred over separate drilling and countersinking steps.

Installation Notes

This tool is installed by machinists and fabricators in drill press chucks or compatible rotary holders. Secure the tool firmly before operation and verify spindle speed is appropriate for the workpiece material and tool diameter. Always power down and lock out the machine before changing or adjusting tooling. Do not exceed the tool manufacturer's recommended feed and speed parameters for high-speed steel cutters.
