Using the Klein Tools 31852 carbide hole cutter is easy. First, make sure you've chosen the right material within the cutter's capacity, like stainless steel, mild steel, iron, copper, or brass sheets up to 3/16 - Inch thick. Attach the cutter to your drill. The split - point pilot drill bit will help keep the bit in place, so you don't have to worry about it wandering. Start drilling slowly at first, then you can increase the speed once the bit is firmly in place. The integrated flange is there to stop you from drilling too deep into the sheet metal, so pay attention to it. As for maintenance, after each use, clean the cutter with a dry cloth to remove any debris. If the pilot bit gets worn out, you can replace it with the 31874 replacement bit. Store the cutter in a dry place to prevent rusting.
