Using this hole saw arbor is easy. First, if you're using it with a quick - change arbor, simply insert the pilot drill bit without the need for any tools. For traditional non - quick - change arbors, follow the normal installation process. When drilling, start at a slow speed and gradually increase as needed. This helps prevent overheating and ensures a clean cut. When working on wood, make sure to support the material well to avoid splintering. For metal, use a lubricant to reduce friction and extend the life of the bit. After each use, clean the arbor and the pilot drill bit with a dry cloth to remove any debris. Store it in a dry place to prevent rusting. And always check the arbor and bit for any signs of wear or damage before using it again.
