KEO Countersink: 120°, 1 Flute, 3/8 in Body Dia

A KEO 120° countersink creates a conical recess for flat-head screws in metalworking. Its single-flute cobalt design cuts quickly in hardened steels and stainless steel, making it ideal for tool and die shops, aerospace maintenance, and general fabrication where precise chamfering is required.

The KEO 919-000-675 is a 120° single-flute countersink with a 3/8 in body diameter, made from cobalt steel. It is designed for fast cutting in tough materials. The cobalt construction provides heat resistance and edge life for repetitive production use.

3G Electric supplies KEO countersinks like the 919-000-675 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial sourcing partner, we provide genuine KEO tooling without requiring a local distributor.

Match the countersink angle to your fastener (82° for standard, 120° for flat-head screws). Choose cobalt for hard steels or high-speed steel for softer materials. Single-flute designs like the KEO 919-000-675 cut faster with less chatter. Always verify body diameter fits your tool holder.
