A steel counterbore set can provide the range of sizes you need for drilling pilot holes properly. A counterbore is a pilot hole with a flat-bottomed opening to accommodate for screw heads. The number of pieces in a counterbore set varies. If you know you’ll need a range of sizes, you may want to opt for a set with as many as 22 pieces. Some sets may include interchangeable pilots, which offer more options and versatility. Organized storage in a wooden case can make for easy use and portability. If you need to work with materials tougher than wood, ensure that the bits in the set you purchase are durable and up for the task.
