ProductDescription : Carbide Counterbores for use with our 6-64 Thread Decorative Pivot Screws. These are carbide so they should last a very long time if you are drilling wood, g10 or phenolic. They will also relieve metal like stainless or titanium but expect them to wear faster. Like all drills, consider these a consumable. Eventually, they will wear enough they have to be replaced. Since they are carbide, they will snap if subjected to side loads where a regular drill bit could handle it. Secure your work piece and keep your drilling straight up and down. If you snap one of these, you own both pieces. To use these: Locate and drill the minor diameter (pilot) holes in your handle material. Insert the counterbore and align the holes and secure your work piece or hold on tight so you don’t bend and break the carbide counterbore. Drill just deep enough for the major diameter to hold the scale in place after your grind the excess corby bolt head away. I eyeball this but you can also set up a gauge and countersink to your exact depth. If you are doing several, use the drill stop on your drill press (finally a use for that!) to set the depth of the counterbore and drill all of them at once. The drill stops occasionally move so check your work frequently in case it slips and goes too deep. NOTE: We have several sizes of counterbores pictured for clarity of illustration. You are ordering one counterbore of the size shown above.
