Greenlee 648 8 Piece Quick Change Carbide Hole Cutter Kit, 1/2 - 2-1/2

Using the Greenlee 648 hole cutter kit is easy. First, pick the right cutter size for your pipe or conduit. Then, attach the cutter to your drill. Make sure to use the appropriate replacement pilot for the cutter size. When you start drilling, the split - point cobalt - steel pilot drill will keep the drill from moving around and make it easier to start the hole. As you drill, the tungsten carbide teeth will cut through stainless steel smoothly, creating accurate holes. The flange stop will prevent you from drilling too far. After each cut, the ejector spring will pop out the slug. To keep your tools in good shape, use the recommended 462 Series Cutting Oil. You can choose between quart and gallon sizes. When not in use, store the cutters in the provided case. Always follow the safety guidelines when using power tools. If you need to replace the pilot, remember to use the correct one according to the cutter size.
