Using the DeWalt DAH3212 hole saw is quite simple. First, make sure your drill is set to the right speed for the material you're cutting. Attach the hole saw to the drill firmly. When you start cutting, apply steady pressure, and let the aggressive tooth design do its job. The saw is designed to cut through tough materials like wood with nails, thick metal, and stainless steel. But always wear safety goggles to protect your eyes from flying chips. As for maintenance, after each use, clean the hole saw with a brush to remove any debris. Check the carbide tips regularly. If they seem dull or damaged, it might be time to replace the saw. Store the saw in a dry place to prevent rust. This way, you can keep getting the best performance out of your DeWalt DAH3212 hole saw.
