Steps of Drilling the Holeįor best results, use a slow and steady speed while drilling. After you’ve drilled the pilot hole, move on to the larger drill bit and keep on drilling to the required diameter. If you’re using a device, it’s a good idea to start with a smaller pilot hole for keeping the bit from walking as you start drilling. Drill a Pilot Hole (for larger step drills) Line up the pilot point with your center mark and you’re ready to start drilling. This is called the pilot point and it’s used to help keep the bit centered while you’re drilling. There should be a small notch near the tip of the bit. Next, you’ll need to find the center of your drill bit. The important thing is that the mark is visible and won’t rub off easily. You can use a pencil or a marker to make the mark.

They are also sometimes called “cone” or “taper” drill bits and are available in a variety of sizes, but most have a diameter range of between 0.125 inches (0.32 cm) and 0.75 inches (19 mm). It is called a “step” drill bit because it has a series of stepped cutting edges that allow it to create precise holes in a variety of thicknesses. This is a device that is used to create holes in metal and plastic. In this guide, we will answer some common questions about using it. This bit has multiple steps, or levels, that allow you to choose the size of hole that you want to drill.
