A action drill bit is really a drill little bit that has the idea floor all the way down to a unique diameter. The transition among this floor diameter and the original diameter is either straight, to sort a counterbore, or angled, to variety a countersink. The edge to this design is both equally diameters contain the exact same flute qualities, which keeps the little get more info bit from clogging when drilling in softer products, including aluminum; in contrast, a drill bit with a slip-on collar does not have exactly the same advantage.
