Keo 906-000-005 Combo Drill Countersink 1/8 in Hss

Product Description

The KEO 906-000-005 is a combination drill and countersink tool designed to perform both drilling and countersinking operations in a single pass. Built from high-speed steel with a bright, uncoated finish, it is suited for use in metal fabrication, machining, and light assembly work. The tool carries a 5/0 trade size, a 1/8-inch body diameter, and an overall length of 1.25 inches. The 118-degree drill point angle and 60-degree included angle make it appropriate for standard countersink profiles in steel, aluminum, and similar materials. It is installed and operated by machinists and tool-and-die professionals.

This combo drill countersink is built in an aircraft style with a double-end configuration, allowing both ends to be used before the tool is retired. Right-hand cutting direction is standard for use with conventional drill presses, CNC machines, and handheld power tools rotating in the standard clockwise direction. The plain cutting edge style and non-tapered body suit general-purpose countersinking tasks in production and maintenance environments alike.

Key Features

• High-speed steel construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish - no coating to chip or peel under use
• 118-degree drill point angle for standard center-drilling and countersinking
• 60-degree included angle for common countersink profiles
• Double-end design extends tool life before replacement
• Aircraft style geometry for precise, consistent results

Compatibility

Designed as a general-purpose combination drill countersink for use in standard drill presses, CNC lathes, and machining centers that accept 1/8-inch shank tooling with right-hand cutting direction.

Installation Notes

This tool is installed and operated by machinists and skilled tradespeople using standard tool holders or collets sized for 1/8-inch shank tooling. Ensure the machine spindle is fully stopped before changing or securing the tool. Verify that the rotation direction of the machine matches the right-hand cutting direction of this tool before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain finish quality.
