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

A KEO 3-flute countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. The three-flute design reduces chatter and provides a smoother finish compared to two-flute tools, making it ideal for general-purpose deburring and countersinking in industrial settings.

The KEO 917-001-011 is a 90° countersink with a 3/4 in body diameter, three flutes, and a TiN-coated carbide construction. The TiN coating increases hardness and lubricity for longer tool life in ferrous and non-ferrous materials. It is a general-purpose three-flute countersink from KEO.

3G Electric supplies KEO countersinks worldwide, handling full logistics and customs clearance for global delivery. As a sourcing partner across 14 industrial departments, we provide genuine KEO cutting tools like the 917-001-011 to procurement teams and plant engineers. Contact us for availability and lead times.

Select a KEO countersink based on the screw head angle (typically 90° for flat-head screws), body diameter matching the screw head size, and material compatibility. For harder materials like stainless steel, choose a TiN-coated carbide version like the 917-001-011 for extended tool life. Always match flute count to material and finish requirements.
