Using the DeWalt DAH43 hole saw is straightforward. First, make sure your drill is set to the appropriate speed for the material you're cutting. Then, align the hole saw with the spot where you want to make the hole and start drilling slowly at first. As the saw bites into the material, you can gradually increase the speed. When cutting through thick or hard materials, don't push too hard. Let the aggressive tooth design do its job. After drilling, use the large, continuous slot to easily remove the plug. For safety, always wear safety goggles to protect your eyes from flying debris. Make sure the workpiece is firmly secured so it doesn't move during the cutting process. To keep your DeWalt DAH43 in top shape, clean it after each use. You can use a brush to remove any chips or debris. Store it in a dry place to prevent rust. If the carbide tips start to show significant wear, it might be time to replace the hole saw. This will ensure you continue to get clean, efficient cuts.
