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

The KEO 100° countersink is used to create a smooth, conical recess for flat-head screws in metalworking and fabrication. Its six-flute design reduces chatter and produces a clean finish on steel, aluminum, and other materials. It is commonly applied in aerospace, automotive, and general manufacturing where precise countersinking is required.

The KEO 919-000-410 is a 100° countersink with six flutes, a 3/16 in body diameter, and a 3/16 in shank. It is made from high-speed steel (HSS) for durability. This smooth-finish countersink is designed for use with standard drill chucks and is suitable for creating clean, burr-free recesses in metal parts.

KEO countersinks, including the 919-000-410, are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead times; we source and deliver genuine KEO tooling to your facility.

Select a KEO countersink based on the screw head angle (e.g., 100° for flat-head screws), material type, and desired finish. For harder metals, choose high-speed steel (HSS) like the 919-000-410. Match the body diameter to the screw head size and ensure the shank fits your drill chuck. Six-flute designs reduce vibration for smoother results.
