KEO Countersink: 100°, 3 Flute, 1 1/2 in Body Dia, 3/4 in Shank

The KEO 100° countersink is used for deburring and countersinking holes in metal, particularly for 100° flat-head screws. It is suitable for general-purpose machining in industrial maintenance, tool-and-die, and fabrication shops, where precise chamfering and burr removal are required.

The KEO 917-000-231 is a 100° countersink with three flutes, a 1 1/2 in body diameter, and a 3/4 in shank. It is made from cobalt steel, offering heat resistance and durability for ferrous and non-ferrous materials. This general-purpose tool is designed for consistent chip evacuation and smooth finishes.

Select the KEO countersink based on hole angle (100° for flat-head screws), material (cobalt for hard metals), and shank size (3/4 in for standard holders). Match body diameter to hole size. For general-purpose deburring, the three-flute design provides balanced cutting. Consult your tooling engineer for specific feed and speed recommendations.
