Keo 906-000-326 Combo Drill Countersink Metric Hss

Product Description

The KEO 906-000-326 is a combination drill and countersink tool machined from high-speed steel with a bright, uncoated finish. It performs drilling and countersinking in a single operation, reducing tool changes and setup time on the machine. The 2.50mm drill point diameter pairs with a 60-degree included angle and a 120-degree drill point angle to produce clean, accurately sized countersinks in metric applications. With a body diameter of 6.30mm and an overall length of 45.00mm, it is sized for benchtop and floor-model drill presses, lathes, and CNC machining centers. Machinists, toolmakers, and maintenance technicians are the primary users.

This combo drill countersink is suited for metric hole preparation work in production and maintenance machining environments. It is designed for countersinking operations where a precisely sized conical seat is required before fastener installation. The right-hand cutting direction and plain cutting edge style make it compatible with standard spindle rotation on conventional and CNC equipment. The double-end style provides two usable ends, extending tool life in high-cycle applications.

Key Features

• Combination drill and countersink design reduces tool changes in a single operation
• High-speed steel construction provides durability across a range of workpiece materials
• Bright uncoated finish suitable for general-purpose metric countersinking
• 60-degree included angle for standard metric countersink profiles
• Double-end design extends usable tool life
• Right-hand cut compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use combo drill countersink for metric countersinking applications on drill presses, lathes, and machining centers accepting standard round-shank tooling.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with cutting tool handling. Secure the tool firmly in the chuck or collet before starting the spindle, and verify that the workpiece is clamped before engaging the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Inspect cutting edges before each use and remove the tool from service if chipping or wear is observed.
