These bits allow you to drill and countersink in one operation and are less likely to clog that 2-piece countersinks especially in aluminum. Step drill are designed to pre-drill clearance holes in the first piece of wood and pilot holes for the threads in the second piece of wood. You will notice that screw sizes are repeated with the only difference being the pilot length (PL). To calculate the length of the pilot hole (PL) you need in the second piece of wood subract the thickness of the first piece of wood from the length of the screw. These countersink bits complete a normal 3-step operation in one step. The countersink angle on all bits is 82 degrees. The shank sizes are the same diameter as the large diameter (LD). Countersinks with long pilots (PL) are not guaranteed against breakage. Special sizes and countersink angles are available upon request. Legend below explains sizing.
