Keo 906-000-020 Combo Drill Countersink 1/8 in Hss Tin

Product Description

The KEO 906-000-020 is a combination drill and countersink designed for creating a centered pilot hole and countersink in a single operation. Sized at 3/0 trade size with a 1/8 inch body diameter, this double-end tool is made from high-speed steel with a titanium nitride (TiN) coating for improved wear resistance and longer tool life. The 118-degree drill point angle and 60-degree included angle deliver clean, accurate entry points. The right-hand cut and plain cutting edge style make it a straightforward choice for machinists, maintenance technicians, and fabricators working in metal.

This combo drill countersink is suited for use in aircraft-style applications and general metalworking where precise center drilling and countersinking are required in one step. The double-end design extends usable tool life by providing two cutting ends. With an overall length of 1.25 inches and a drill point diameter of 0.020 inches, it is well-matched for small-diameter, close-tolerance work on the bench or in a drill press setup.

Key Features

• Double-end design doubles usable cutting life compared to single-end tools
• High-speed steel construction withstands heat generated during metal cutting
• Titanium nitride (TiN) coating reduces friction and extends tool life
• 118-degree drill point angle suits standard metalworking center-drill applications
• 60-degree included angle for accurate countersink geometry
• Aircraft-style configuration for precision small-diameter work

Compatibility

Designed as a standard combination drill countersink for use in drill presses, CNC machines, and manual lathes where 3/0 trade size center drilling and countersinking in metal are required.

Installation Notes

This tool is installed in a standard drill chuck or collet by a machinist or maintenance technician. Ensure the machine is powered off and the spindle is fully stopped before changing or inspecting the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain cut quality. Follow shop safety procedures and applicable machine guarding requirements during operation.
