KEO 90° Four-Flute Machine Countersink, 1/2 in Body Dia, High Speed Steel

A KEO 4-flute countersink creates a 90° chamfer or countersink hole in metal, plastic, or wood. It is commonly used in machining and fabrication to prepare holes for flat-head screws or to deburr edges. The four-flute design provides smooth cutting and reduces chatter.

The KEO 919-000-005 is a 90° countersink with four flutes, a 1/2 in body diameter, and is made from high-speed steel. It is designed for machine use and produces a clean, countersunk hole. The 4-flute geometry improves cutting efficiency and finish quality.

Select a KEO countersink based on the required chamfer angle (90° is standard for flat-head screws), body diameter matching your hole size, and material compatibility. High-speed steel suits general-purpose machining. For harder materials, consider cobalt or carbide options. Always match flute count to desired finish.
