KEO Countersink: 90°, 6 Flute, 3/8 in Body Dia

A KEO 6-flute countersink creates smooth, chatter-free 90° chamfers and countersinks in metal, plastic, and wood. Its six-flute design reduces vibration for a superior finish, ideal for aerospace, automotive, and general machining applications where precision and surface quality are critical.

The KEO 919-000-380 is a 90° countersink with a 3/8 in body diameter, 6 flutes, and TiN-coated high-speed steel construction. The TiN coating extends tool life and reduces friction. It is designed for smooth-finish countersinking in a variety of materials.

3G Electric supplies KEO countersinks like the 919-000-380 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other KEO tooling across our 14 industrial departments.

Select a KEO countersink based on the required chamfer angle (e.g., 90°), body diameter matching your hole size, and material. For harder materials, choose TiN-coated high-speed steel like the 919-000-380 for longer life. Match flute count to finish needs—6 flutes minimize chatter for smooth results.
