Using this hole cutter kit is easy. First, select the right - sized hole cutter for your project based on the conduit or pipe size you're working with. Attach the hole cutter to your drill and make sure it's securely fastened. Place the split - point pilot drill bit on the spot where you want to make the hole. The split - point design will help keep the bit in place and prevent it from walking. Start drilling slowly at first, then gradually increase the speed. The integrated flange will stop you from drilling too deep into the sheet metal. When you're done, remove the hole cutter carefully. As for maintenance, after each use, wipe the hole cutters and pilot bits clean to remove any debris. You can use a little bit of lubricant to keep them in good working condition. Store the kit in its rust - proof, molded plastic carrying case to protect it from damage and rust. Also, make sure to keep the kit out of reach of children.
