KEO Countersink: 120°, 6 Flute, 5/8 in Body Dia

The KEO 120° 6-flute countersink is designed for creating smooth, burr-free 120-degree chamfers on drilled holes in metal, plastic, and wood. Its six-flute design reduces chatter and vibration, making it ideal for precision deburring and countersinking in industrial machining, automotive, and aerospace applications.

The KEO 919-000-496 is a 120° countersink with six flutes, a 5/8 in body diameter, and is made from high-speed steel (HSS). It is part of KEO's Smooth-Finish Six-Flute Countersinks line, designed for clean, chatter-free operation on ferrous and non-ferrous materials.

KEO countersinks, including the 919-000-496, are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive genuine KEO tooling without supply-chain delays.

To select the right KEO countersink, match the included angle (e.g., 120°) to your fastener's head angle, choose flute count based on material hardness (6-flute for smoother finish), and verify body diameter (5/8 in) fits your drill chuck. For high-speed steel tools, use moderate RPM and coolant for extended tool life.
