Greenlee 625-1-3/8 CUTTER, HOLE-CARBD (1.375,35.0M

Using the Greenlee 625 - 1 - 3/8 hole cutter is quite straightforward. First, make sure you've got the right surface to work on, like stainless steel, copper, aluminum, or steel. Attach the bit to your drill and you're ready to start making holes. Before you start drilling, place the cutter on the spot where you want the hole. The flange stop will prevent you from drilling too deep, so you don't have to worry about that. When you turn on the drill, the multiple tungsten carbide tips will cut through the material smoothly and quickly, giving you an accurate and high - quality hole. As for the replaceable cobalt steel pilot drill with the split - point tip, it helps keep the cutter in place and reduces the chance of it wandering around. You don't even need a center punch. When you're done using the cutter, clean it with a dry cloth to remove any debris. Store it in a dry place to prevent rust. If the pilot drill gets dull, you can easily replace it to keep the cutter working at its best.
