KEO Countersink: 60°, 3 Flute, 1 3/4 in Body Dia, 3/4 in Shank

The KEO 60° countersink is used for deburring and countersinking holes in metal, creating a 60-degree chamfer for fastener heads. It is common in general machining, tool and die work, and maintenance applications where a precise, smooth finish is required on steel, stainless steel, and other alloys.

The KEO countersink has a 60° included angle, 3 flutes, 1 3/4 in body diameter, and 3/4 in shank diameter. It is made from cobalt steel (MPN 917-000-173). The three-flute design reduces chatter and provides a balanced cut for general-purpose countersinking in industrial settings.

You can source the KEO 60° countersink 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; we supply genuine KEO tooling for your machining operations.

Select a KEO countersink based on the required chamfer angle (60° for standard fastener seats), material hardness (cobalt for tough alloys), and shank size matching your toolholder. For hole diameters up to 1 3/4 in, this 3-flute model provides stable cutting. Always match the countersink diameter to the fastener head size.
