Using the DeWalt IMPACT CONNECT Inside Pipe Cutter Attachment is easy. First, make sure your impact driver or drill accepts a 1/4 in. hex shank and attach the pipe cutter. Then, choose the appropriate PVC pipe within the size range of 1 - 1/4 in. to 8 in. schedule 40. Start your impact driver and guide the cutter along the pipe to make a cut. When you're done with cutting and want to drive screws, simply remove the attachment. For safety, always wear safety goggles and gloves when using this tool. Keep your hands away from the cutting edge while it's in motion. When it comes to maintenance, after each use, clean the cutter to remove any debris. Check the diamond - grit cutting edge regularly. If it shows signs of excessive wear, it might be time to replace the attachment. Store the cutter in a dry place to prevent rust and damage.
