Frequently Asked Questions

What is a KEO 90° countersink used for?

A KEO 90° countersink with four flutes is used to create a conical recess for flat-head screws in metalworking and machining. The 1-inch body diameter and TiN coating on cobalt steel provide wear resistance for production deburring and countersinking on ferrous and non-ferrous materials.

What are the specifications of the KEO countersink 919-000-548?

The KEO countersink model 919-000-548 has a 90° included angle, four flutes, a 1-inch body diameter, and a TiN (titanium nitride) coating on cobalt steel. It is a machine countersink designed for industrial drilling and milling applications requiring precise chamfering.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (typically 90° for flat-head screws), material hardness (TiN-coated cobalt for steels), and flute count (four flutes for smoother finish). Match the body diameter to the screw head size. For high-production runs, consider the coating for extended tool life.
