Keo 906-000-330 Combo Drill Countersink Metric Hss

Product Description

The KEO 906-000-330 is a combination drill and countersink designed for metric applications in metal fabrication and machining operations. Built from high-speed steel with a bright, uncoated finish, this tool combines a center drill point with a countersinking function in a single pass. The 120-degree drill point angle and 60-degree included angle make it suited for creating precise countersunk holes and center locations in steel, cast iron, and similar ferrous materials. At 71 millimeters overall length with a 6.30-millimeter drill point diameter and 16.00-millimeter body diameter, it fits standard toolholders used in lathes, mills, and drill presses. Right-hand cutting direction is standard for conventional spindle rotation.

This combo drill countersink is used in job shops, production machining environments, and maintenance shops where metric countersinking is required. The double-end design extends tool life by providing two usable cutting ends, reducing downtime for tool changes. It is appropriate for use on manual lathes, CNC turning centers, and bench drill presses where center drilling and countersinking are performed in a single operation.

Installation Notes

Installation is performed by machinists and tool and die professionals. Secure the tool in a properly sized collet or chuck before use, and confirm the toolholder is tight before engaging the spindle. Power down the machine completely before changing or inspecting the tool. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish quality.
