KEO Countersink: 120°, 3 Flute, 1/2 in Body Dia

The KEO 120° countersink is designed for deburring and countersinking holes in metal, plastic, and wood. Its 120° included angle suits flat-head screws and aerospace applications. The three-flute design provides smooth cutting and reduced chatter, making it ideal for general-purpose machining in fabrication and maintenance shops.

The KEO 917-000-987 is a 120° countersink with three flutes and a 1/2 in body diameter. It features an AlTiN (aluminum titanium nitride) coating on high-speed steel for increased wear resistance and heat tolerance. This general-purpose tool is suitable for ferrous and non-ferrous materials.

Select a KEO countersink based on the required angle (e.g., 120° for flat-head screws), material hardness, and hole size. The 1/2 in body diameter suits medium-duty work. For harder materials, the AlTiN coating on high-speed steel improves tool life. Match flute count to desired finish: three flutes reduce vibration for cleaner results.
