Using the DeWalt DWACM1822 holesaw is easy. First, make sure your drill is set to the appropriate speed for metal cutting. Attach the holesaw to your drill tightly. When you start drilling, apply gentle and steady pressure. The ejection spring will help you remove the plug easily after each cut. Be careful not to push too hard, as the raised shoulder is there to prevent breakthroughs. When it comes to maintenance, after each use, clean the holesaw with a brush to remove any metal shavings. You can also use a little bit of lubricant on the teeth to keep them in good condition. Store the holesaw in a dry place to avoid rusting. If you notice the teeth are getting dull, it might be time to replace the holesaw for optimal performance.
