Frequently Asked Questions

What is a KEO counterbore used for?

A KEO counterbore creates a flat-bottomed recess for a bolt head or nut, allowing it to sit flush with or below the workpiece surface. This built-in-pilot design for 1/2" screws ensures concentric alignment with an existing hole, common in metalworking and machining applications.

What are the specifications of the KEO counterbore 902-000-306?

The KEO counterbore model 902-000-306 has a 3/4 in bore diameter and a 0.5 in pilot diameter. It is made from AlTiN coated cobalt, designed for standard use with 1/2" screws. The built-in-pilot type ensures precise alignment during operation.
