Using the Makita 714008-A bi-metal hole saw is easy. First, make sure you've got the right Makita Arbor (714060-B, 714061-B or 714062-B with 1/2' - 120 thread) attached. Once it's set up, you can start cutting through wood or steel. Just apply steady pressure as you drill. When cutting, don't push too hard as the 4/6 variable pitch teeth and extra-hard high-speed steel teeth are designed to do the work efficiently. As for maintenance, after each use, wipe off any debris from the teeth and the steel body. Store it in a dry place to prevent rust. Also, avoid dropping the saw as its flexible body, though shatter-resistant, could still get damaged. And always check the teeth for wear and tear. If they're too worn, it might be time to get a new saw.
