KEO 90° Anti-Vibration Zero-Flute Countersink

A KEO zero-flute countersink is used to create a conical recess for flat-head screws in metalworking. Its anti-vibration design reduces chatter, producing a smooth finish. It is ideal for deburring holes and countersinking in steel, stainless steel, and other hard materials, commonly used in aerospace, automotive, and general manufacturing.

The KEO 919-000-230 is a 90° countersink with 0 flutes, a 1-inch body diameter, and TiN-coated cobalt construction. The TiN coating increases hardness and lubricity for longer tool life. It is designed for anti-vibration performance, reducing chatter during operation. The manufacturer part number is 919-000-230.

Select a KEO countersink based on the screw head angle (typically 90° for flat-head screws), material hardness, and desired finish. For hard materials like stainless steel, choose a TiN-coated cobalt version like the 919-000-230. Zero-flute designs reduce vibration, while fluted versions are better for softer materials. Match body diameter to your tool holder.
