Using this Lenox hole saw arbor pilot bit is easy. First, if you're using it with a LENOX Snap - Back® Arbor, take advantage of the quick - change feature and insert the bit without any tools. For traditional non - quick - change arbors, follow the normal installation process. When drilling, make sure to select the appropriate speed based on the material you're working with - slower for metal and a bit faster for wood. As for safety, always wear protective goggles to avoid any flying debris. When not in use, store the bit in a dry place to prevent rusting. If the bit gets dull over time, you can consider sharpening it or replacing it to maintain its performance.
