KEO Countersink: 100°, 1 Flute, 3/4 in Body Dia

The KEO 100° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its single-flute design provides fast, chatter-free cutting in steel, aluminum, and other materials, making it ideal for deburring and countersinking holes in industrial manufacturing.

The KEO 919-002-864 is a 100° countersink with a single flute and a 3/4 in body diameter. It features an AlTiN (aluminum titanium nitride) coating on high-speed steel for enhanced wear resistance and longer tool life. This fast-cutting countersink is designed for precision chamfering in production environments.

KEO countersinks are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact our team for pricing and lead time on the KEO 919-002-864 or other KEO cutting tools.

Select a KEO countersink based on the screw head angle (e.g., 100° for metric flat-head screws) and the required body diameter to match your hole size. The single-flute design is best for fast, clean cuts in softer materials, while the AlTiN coating on high-speed steel improves performance in harder alloys. Always match the tool to your material and RPM.
