Lenox 18CHC 1-1/8 Carbide Hole Saw with Spring

Using this Lenox hole saw is easy. First, make sure you're working on a stable surface. Attach the hole saw to your drill according to the drill's instructions. When you're ready to start cutting, position the split - point pilot bit on the spot you want to cut. This will help the saw start quickly. Press gently on the drill and let the precisely ground teeth do the work. It's ideal for sheet metal, so it will cut through smoothly. 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. And always wear safety goggles when using the hole saw to protect your eyes from flying debris.
