China Step Dril Bit Suppliers

step Drill Bit is a drill bit that has the tip ground down to a different diameter. The transition between this ground diameter and the original diameter is either straight, to form a counterbore, or angled, to form a countersink.

The advantage to this style is that both diameters have the same flute characteristics, which keeps the bit from clogging when drilling in softer materials, such as aluminum;. Most of these bits are custom-made for each application, which makes them more expensive.
