Keo 906-000-322 Combo Drill Countersink Metric Hss

Product Description

The KEO 906-000-322 is a combination drill and countersink designed for metric applications in high-speed steel (HSS) construction. This tool performs center drilling and countersinking in a single operation, reducing setup time and tool changes on the machine. The bright, uncoated finish suits general-purpose use across a range of workpiece materials. With a 120-degree drill point angle and a 60-degree included angle, it produces accurate center holes and countersunk seats for metric fasteners. Right-hand cutting direction is standard. The double-end configuration extends tool life by providing two usable cutting ends.

This combo drill countersink is used in metalworking and machining environments where metric center holes and countersinks are required in a single pass. Typical applications include lathe center drilling, pre-drilling for countersunk screws, and deburring or chamfering operations. The plain cutting edge style and non-tapered body make it compatible with standard drill chucks and collet holders. It is suited for use in manual and CNC lathes, mills, and drill presses in job shops, production machining, and maintenance environments.

Compatibility

Designed as a general-purpose metric combination drill countersink for use in standard drill chucks and collet-style holders on lathes, mills, and drill presses where a 120-degree point and 60-degree countersink angle are required.

Installation Notes

Installation is performed by machinists or tooling technicians. Secure the tool firmly in a compatible drill chuck or collet holder before use and verify runout before engaging the workpiece. Power down the machine completely before changing or adjusting the tool. Do not exceed the recommended speed and feed range for the workpiece material and tool diameter.
