We reveal to you the true use of STEP DRILL BITS for DRILLS.

Step drill bits are drill bits that have the shape of a cone, with steps of the same profile, but with different diameters, ranging from smallest to largest, starting with the tip, which begins the drilling.

These allow you to increase the diameter of the holes and are especially used in drilling thin metal, as well as in different plastics, PVC and polycarbonates.

Note: In some countries, it is also known as a stepped wick.
