Frequently Asked Questions

What is the KEO counterbore for M12 screw used for?

The KEO counterbore is used to create a flat-bottomed recess for an M12 screw head, allowing it to sit flush with or below the workpiece surface. It is commonly applied in metalworking and machining operations where a clean, countersunk finish is required for bolted assemblies.

What are the specifications of the KEO counterbore 902-000-066?

The KEO counterbore 902-000-066 is a standard cobalt tool for M12 screws, with a 20 mm bore diameter and a 14 mm pilot diameter. It is manufactured by KEO and designed for built-in-pilot applications, ensuring precise alignment during use.

Where to buy KEO counterbore 902-000-066 worldwide?

3G Electric supplies the KEO counterbore 902-000-066 worldwide, handling full logistics and customs clearance for international delivery. As a global industrial solutions provider, we source and deliver this tool to support your machining needs across 14 industrial departments.

How to select the correct pilot diameter for a KEO counterbore?

Select a pilot diameter that matches the existing hole or the screw's clearance hole. For the KEO counterbore 902-000-066, the 14 mm pilot fits a pre-drilled hole for M12 screws. Always verify the pilot fits snugly to prevent chatter and ensure concentricity during counterboring.
