KEO Countersink: 100°, 6 Flute, 3/16 in Body Dia, 3/16 in Shank

The KEO 100° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its six-flute design produces a smooth finish, reducing chatter and improving surface quality. It is suitable for use on steel, stainless steel, and other alloys, commonly in aerospace, automotive, and general manufacturing.

The KEO countersink has a 100° included angle, 6 flutes, a 3/16 in body diameter, and a 3/16 in shank. It is made from cobalt steel for heat resistance and durability. The manufacturer part number is 919-000-803. This tool is designed for smooth-finish countersinking in hard materials.

Select the KEO countersink based on screw head angle (100° for flat-head screws), material hardness (cobalt for tough alloys), and shank size matching your tool holder. The 3/16 in shank fits standard collets. For best results, match flute count to finish requirements—six flutes reduce vibration and improve surface smoothness.
