Keo 906-000-332 Combo Drill Countersink Metric Hss

Product Description

The KEO 906-000-332 is a combination drill and countersink designed for metric applications in high-speed steel (HSS) construction. It performs simultaneous drilling and countersinking in a single pass, reducing tool changes and setup time on the machine. The cutting geometry features a 120-degree drill point angle and a 60-degree included countersink angle, with a plain cutting edge and right-hand cut direction. Finished with a bright, uncoated surface, this tool is well suited for general-purpose metalworking in production and job-shop environments. It is handled by machinists and toolmakers working with drill presses, lathes, and CNC equipment.

This combo drill countersink is built for metric countersinking operations on ferrous and non-ferrous materials. The double-end design extends tool life by providing two usable cutting ends, making it practical for high-volume production runs. At 100.00 mm overall length with a 10.00 mm drill point diameter and 12.80 mm drill point length, it fits standard toolholders used in light to medium machining setups. The body measures 25.00 mm in diameter. This tool is not an aircraft-style countersink and is not designed for tapered hole applications.

Key Features

• 120-degree drill point angle for metric countersinking in a single operation
• 60-degree included countersink angle with plain cutting edge style
• High-speed steel construction for durability across general metalworking applications
• Double-end design provides two cutting ends, extending usable tool life
• Bright uncoated finish suits a wide range of materials without coating compatibility concerns
• Right-hand cut direction for use in standard rotating machine spindles

Compatibility

Designed as a general-purpose metric combo drill countersink suitable for standard drill press, lathe, and CNC toolholder setups requiring a 25.00 mm body diameter and right-hand cut tooling.

Installation Notes

Installation and operation of this tooling should be performed by a qualified machinist familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and the tool is properly secured in the holder before beginning any setup. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed recommendations based on material type. Do not exceed the tool diameter rating of the toolholder being used.
