Review on 🔩 Greenlee 34403 Multi Hole Step Drill Bit by Jacob Ferrarini

You can't buy a better bit than GreenLee. The reason I say this is because it is the ONLY bit that is ribbed on both sides. Most other devices have a flute for extracting metal chips. Greenleys have two, which means less cutting resistance and faster drilling because the metal can come out of the dill faster. Use them daily to drill holes in steel and aluminum for electrical work.
