Using the Makita B - 68666 bit is easy. First, make sure your rotary hammer accepts SDS - PLUS shank bits. Then, insert the bit into the hammer. When you start drilling, the aggressive centering tip will quickly get the hole started. The 3 - cutter design will efficiently cut through concrete or reinforced concrete. Remember, the steel stop collar is there to prevent over - drilling, so keep an eye on it for precise anchor installations. As for maintenance, after each use, clean the bit to remove dust and debris. You can use a brush or compressed air. Store it in a dry place to prevent rust. If the bit becomes dull or damaged, it's time to replace it for continued good performance.
