Using the Klein Tools 31856 carbide hole cutter is easy. First, make sure your workpiece is properly secured. Then, attach the hole cutter to your drill. The split - point pilot drill bit helps start the hole accurately, so align it with the spot where you want to drill. When you start drilling, apply steady pressure. The integrated flange will stop you from drilling too deep into the sheet metal. Remember to use the replacement pilot bit 31874 when the existing one wears out. As for maintenance, after each use, clean the hole cutter with a dry cloth to remove any debris. Store it in a dry place to prevent rust. Also, check the bit regularly for any signs of damage and replace it if necessary. This way, your hole cutter will last a long time and keep performing well.
