KEO Countersink: 120°, 1 Flute, 1 3/4 in Body Dia, 3/4 in Shank

The KEO 120° countersink is used for deburring and countersinking holes in metal, plastic, or wood. Its 120° included angle is ideal for creating a conical recess for flat-head screws. The single-flute design provides fast, chatter-free cutting in production and maintenance applications.

The KEO 919-000-177 is a 120° single-flute countersink with a 1 3/4 in body diameter and a 3/4 in shank. It is made from high-speed steel (HSS) for durability. The 1-flute geometry enables aggressive material removal. This KEO tool is designed for general-purpose countersinking in ferrous and non-ferrous materials.

Select a KEO countersink with a body diameter larger than the screw head you are countersinking. The shank must match your toolholder's capacity. For flat-head screws, use a 120° countersink. Match the flute count to your material: single-flute for fast cutting in softer metals, multi-flute for harder alloys.
