Frequently Asked Questions

What is a KEO counterbore used for?

A KEO counterbore creates a flat-bottomed recess for a bolt head or screw, allowing it to sit flush with or below the workpiece surface. This KEO built-in-pilot counterbore is designed for 1/4" screws and is used in machining and metalworking applications that require precise, repeatable counterboring.

What are the specifications of the KEO 902-000-016 counterbore?

The KEO 902-000-016 is a standard-type built-in-pilot counterbore for 1/4" screws. It has a 3/8 in bore diameter, a 0.25 in pilot diameter, and is made from cobalt. This tool is suitable for industrial counterboring operations where dimensional accuracy is critical.

Where to buy KEO counterbore 902-000-016 worldwide?

3G Electric supplies the KEO 902-000-016 counterbore to customers worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to deliver this cobalt counterbore to your facility. Contact us for pricing and lead time on this standard-type tool.

How to select the correct KEO counterbore for a 1/4" screw?

Select a KEO counterbore with a pilot diameter that matches the existing hole and a bore diameter that accommodates the screw head. For a 1/4" screw, the KEO 902-000-016 uses a 3/8 in bore and 0.25 in pilot. Always verify the tool material—cobalt offers heat resistance for harder workpieces.
