HOW TO USE A SPOT WELD DRILL BIT?

Locate the spot-weld, it’s helpful, but not necessary, to use a pilot punch first, then mark the target with an industrial sharpie or other metal marker. Measure the surface area and determine the best size, go as small as possible to eliminate excess material evacuation. Recommended drilling RPM is 500. Again, it is not necessary, but using cutting oil will prolong the tool life. Use minimal pressure, let the bit do the work, our babies will eat through your weld like a hot knife in cold butter.
