Frequently Asked Questions

What is the KEO 82° countersink used for?

The KEO 82° countersink is used to create a conical recess for flat-head screws in metalworking. Its 82-degree angle matches standard flat-head fastener angles, making it ideal for deburring and countersinking holes in industrial manufacturing and maintenance applications.

What are the specifications of the KEO 917-000-289 countersink?

The KEO 917-000-289 is a four-flute machine countersink with an 82° included angle. It has a 1 3/4 in body diameter and a 3/4 in shank, made from cobalt steel for heat resistance and durability in high-speed machining of hard materials.

How to select the right KEO countersink for my application?
