KEO Countersink: 90°, 3 Flute, 1 1/4 in Body Dia

A KEO 90° countersink is used to create a conical recess in a workpiece, typically for countersunk screws or rivets. The 90° angle is standard for flat-head fasteners. The three-flute design provides smooth cutting and reduces chatter in general-purpose metalworking applications.

The KEO 917-000-107 is a 90° countersink with three flutes and a 1 1/4 in body diameter. It is made from high-speed steel (HSS) for durability in general-purpose machining. The manufacturer part number is 917-000-107, and it is designed for use on ferrous and non-ferrous materials.

Select a KEO countersink based on the required angle (e.g., 90° for standard flat-head screws) and body diameter matching the fastener head size. For general-purpose work, high-speed steel (HSS) is suitable. Ensure the shank fits your tool holder. KEO offers various flute counts; three-flute designs reduce vibration.
