KEO Countersink: 82°, 6 Flute, 3/16 in Body Dia, 3/16 in Shank

A KEO 6-flute countersink creates a smooth, chamfered recess for flat-head screws in metalworking. The six-flute design reduces chatter and vibration, producing a finer finish than standard countersinks. It is commonly used in machining, tool and die, and aerospace applications where surface quality is critical.

The KEO 919-000-731 is an 82°, 6-flute countersink with a 3/16 in body diameter and a 3/16 in shank. It is made from cobalt steel for heat resistance and durability. This smooth-finish countersink is designed for precision chamfering in hard materials and is manufactured by KEO.

3G Electric supplies KEO countersinks like the 919-000-731 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine KEO cutting tools and support your procurement with technical expertise across machining and metalworking applications.

Select a KEO countersink based on screw head angle (82° for inch fasteners), material hardness (cobalt for tough alloys), and desired finish. Six-flute designs minimize chatter for smoother results. Match body diameter to hole size and shank diameter to your tool holder. For high-volume production, consider coolant-through options.
