Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used to create a conical recess in metal or plastic for flat-head screws. Its 3-flute design provides smooth cutting and reduced chatter. The AlTiN coating on cobalt steel extends tool life in abrasive materials like stainless steel.

What are the specifications of the KEO 917-000-863 countersink?

This KEO countersink has a 100° included angle, 3 flutes, a 1 3/4 in body diameter, and a 3/4 in shank. It is made from AlTiN coated cobalt steel. The manufacturer part number is 917-000-863. It is designed for general-purpose countersinking in industrial applications.

How to select the correct KEO countersink size?

Select a KEO countersink with a body diameter larger than the screw head you are countersinking. The shank diameter must match your tool holder. For 100° flat-head screws, use a 100° countersink. The 1 3/4 in body and 3/4 in shank suit medium-duty work in steel or aluminum.
