Using this DeWalt hole saw is quite simple. First, make sure the hole saw is properly attached to your drill. Then, mark the spot on the metal where you want to drill. Start the drill at a slow speed and gradually increase it as the hole saw bites into the metal. The optimized tooth design will help you drill quickly. When the hole is complete, the ejection spring makes it easy to remove the plug. As for maintenance, after each use, wipe the hole saw clean to remove any metal shavings. Store it in a dry place to prevent rust. Be careful when using it, as the raised shoulder is there to stop the drill from breaking through, but still pay attention to avoid any potential damage.
