Specifications

Step drill bit are drill bits that are shaped like a cone and are comprised of multiple sizes, or steps, in a single package. These can be anywhere from two to 13 different bit sizes in increments of 1/32 inch to 3/4 inch, or 4 to 12 millimeters. The user simply starts the drill bit into the part to be drilled and pushes the bit in until the desired size hole has been drilled. The benefit is a step drill bit is that most are rated to last up to six times longer than a conventional drill bit.

Step drill bit are are not intended for use on wood, however. One particular use for these drills is with sheet-metal work. When the need for multiple sized holes would require the user to change drill bits over and over, step drills save time and expense in many cases over conventional drill bits. Use a drill bit with step increments slightly larger than the materials thickness that is to be drilled. By design, step drills are limited to use on thin material.

Beyond being a versatile drill bit, step drill bit can also serve as a countersink, which allows for screws and fasteners to be drilled below the surface. Counter boring is another use for these bits.
