KEO Countersink: 60°, 4 Flute, 7/8 in Body Dia

The KEO 60° countersink is used to create a conical recess in a workpiece, typically for deburring holes or allowing a flat-head screw to sit flush with the surface. It is common in metalworking and machining applications where precision chamfering is required.

This KEO countersink has a 60° included angle, 4 flutes, and a 7/8 in body diameter. It is made from high-speed steel (HSS) and is identified by MPN 919-000-019. The four-flute design provides smooth cutting action and reduces chatter during operation.

KEO countersinks 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 time on the KEO 919-000-019 or other KEO tooling.

Select a KEO countersink based on the required chamfer angle (60° is common for screw heads), material hardness (HSS suits most metals), and hole size. Match the body diameter to your workpiece clearance. For deburring, a 4-flute design like this KEO model provides balanced cutting and longer tool life.
