Greenlee 628 8 Piece Carbide Hole Cutter Kit, 7/8 - 2-1/2

Using the Greenlee 628 Hole Cutter Kit is a breeze. First, pick the right cutter size for your pipe or conduit. Make sure to attach the correct pilot drill as per the cutter size. When you start drilling, apply steady pressure. The split - point pilot drill will stop the drill from moving around and help it penetrate easily. The ejector spring will automatically get rid of the slug after each cut. Remember, using Greenlee's 462 Series Cutting Oil during drilling is a great idea. It reduces heat and friction, which helps the cutters last longer. Also, don't forget the flange stop. It's there to prevent over - drilling and keep you safe. As for maintenance, clean the cutters after each use. If a pilot drill gets worn out, replace it with the correct replacement part (Greenlee 625 - 001 for cutters up to 2 inches and Greenlee 625 - 002 for the 2 - 1/2 inch cutter). Store the kit in the provided case to keep the cutters protected and organized.
