A countersink drill bit is the best way to ensure that screws have solid pilot holes to enter and the head lies flush with the wood. A set of countersink drill bits ensure that you can drill pilot holes for a variety of screw sizes. Some drill bits are made for hard materials like steel or insulation board, so make sure that the set you select meets your needs. Be sure to carefully match your bits to the screws you intend to use, as getting the pilot hole diameter right is the key to creating a solid anchor. The drill collar can be adjusted to match the length of your screws so you don’t have to think about depth as you drill.
