How to Use
Select the drill size required for the hole and use the 126CO with a compatible power drill, drill press or CNC machine. Use the correct speed, feed, workholding and cutting fluid for the material, and clear chips regularly.
Important: Cobalt drills are heat-resistant but brittle. Avoid side loading, excessive feed pressure and forcing the tool.
Cutting tools may chip or shatter if misused or overloaded. Secure the workpiece, wear eye protection and follow the drill and machine manufacturer's operating instructions.
