Keo 906-000-076 Combo Drill Countersink Size 2 Hss Tin

Product Description

The KEO 906-000-076 is a combination drill and countersink designed for simultaneous center-drilling and countersinking in a single operation. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life in ferrous and non-ferrous materials. The body measures 3/16 inches in diameter with a 5/64-inch drill point and a 1-7/8-inch overall length. The 60-degree included angle and 118-degree drill point angle make it well suited for producing clean, accurate center holes and countersink seats. This is a right-hand cut, plain cutting edge tool sold individually.

This combo drill countersink is used in machine shops, fabrication environments, and maintenance applications where center holes or countersink seats must be produced quickly and accurately. It fits standard drill chucks and collet holders on lathes, milling machines, drill presses, and CNC equipment. The double-end configuration extends usable tool life by providing two cutting ends per piece. Machinists, toolmakers, and maintenance mechanics are the primary users of this style of tool.

Key Features

• High-speed steel construction with TiN coating for improved wear resistance
• 60-degree included angle for standard countersink seat geometry
• 118-degree drill point angle compatible with common center-drilling applications
• Double-end design extends tool life by offering two usable cutting ends
• Right-hand cut, plain cutting edge for straightforward chuck or collet mounting

Compatibility

Designed as an OEM-style replacement or standard supply item for machine shop and industrial maintenance applications requiring a size 2 combination drill countersink with a 3/16-inch body diameter.

Installation Notes

Installation is performed by machinists or toolmakers holding the tool in a drill chuck or collet sized to the 3/16-inch body diameter. Secure the tool firmly before operation and verify spindle speed is appropriate for the workpiece material. Ensure the machine is fully stopped and de-energized before changing or inspecting the tool. Do not exceed the recommended depth of cut for the drill point diameter.
