A Step Drill Bit has “stairs” that allow the user to drill a wide range of hole sizes. The further you drill, the larger the hole. The first step of the bit is sized to pilot on the square hole found in every piece of VEX metal. By piloting to the square hole, you can better locate holes you’re drilling out, and ensure the holes are straight. Great for drilling VEX metal to be compatible with High Strength Shafts, Hardware, and bearings!
