KEO Countersink: 100°, 3 Flute, 1 in Body Dia

The KEO 100° countersink is used to create a conical recess for flat-head screws in metalworking. Its 100° included angle suits aerospace and general manufacturing applications. The three-flute design provides smooth cutting and reduces chatter, making it ideal for deburring holes in steel, stainless steel, and other alloys.

The KEO 917-000-227 is a general-purpose three-flute countersink with a 100° included angle and a 1-inch body diameter. It is made from cobalt high-speed steel for heat resistance and durability. The 3-flute geometry ensures balanced cutting and efficient chip evacuation in ferrous and non-ferrous materials.

KEO countersinks are available to order through 3G Electric, a global industrial equipment distributor. We source and deliver KEO cutting tools to worldwide destinations, handling logistics, customs clearance, and delivery. Contact 3G Electric for pricing and lead time on the KEO 917-000-227 countersink.

Select a KEO countersink based on the screw head angle—100° for metric flat-head screws. Match the body diameter to the hole size and material hardness. For hardened steels, choose cobalt HSS like the 917-000-227. Use a three-flute design for smoother finishes and reduced vibration in production runs.
