Using the Bosch SP515 Five - Piece Hex Shank Screw Pilot Bit Set is easy. First, choose the right bit from the set for your project, based on the size of the screw you'll be using. Insert the bit into your drill - it fits both corded and cordless drills. If you need to adjust the countersink depth, use the included Allen® wrench. Then, position your drill on the material (wood, plastic, or composite) where you want to drill and start the drill. Remember to keep a firm grip on the drill to ensure a straight hole. When you're done using the bits, clean them with a dry cloth to remove any debris. Store the set in a dry place to prevent rusting. Also, make sure to replace the drill bits when they get too worn out to keep getting the best results.
