Using your DeWalt DAH42916 hole saw is a breeze. First, make sure your drill is set to the appropriate speed for the material you're cutting. Whether it's wood with nails, thick metal, or stainless steel, this hole saw can handle it. Just place the hole saw on the surface where you want to make a hole and start drilling. As you drill, the aggressive tooth design will cut through the material and efficiently remove chips, so you don't have to worry about too much heat building up. Once you've drilled through, use the multiple leverage points provided by the large, continuous slot to easily remove the plug. When it comes to maintenance, after each use, wipe down the hole saw to remove any debris. Store it in a dry place to prevent rust. And always remember to wear safety goggles when using this tool. This hole saw is made with high - quality materials and advanced welding technology, so with proper use and care, it will last you a long time, outperforming Milwaukee®* by up to 3 times.
