Greenlee 645-011 Quick Change Carbide-Tipped Arbor For 5/8 to 2-1/4 Cutters, 3/8 Shank

Using the Greenlee 645-011 is a breeze. First, make sure your drill chuck meets the minimum 3/8-inch size requirement. You can easily swap out cutter heads for different cutting needs just by giving it a push and a turn. When cutting stainless steel, this tool works quickly and smoothly. The flange stop will help you avoid drilling too deep. For sizes larger than 3/4 inches, the ejector spring will make it easier to get rid of the slug. Remember, the pilot drill has a split-point tip to keep it from moving around. As for maintenance, check the carbide teeth regularly. If they show signs of wear, it might be time to replace them. Also, keep the arbor clean and dry to ensure it lasts a long time.
