We’re used to high quality wood bits, but the new Bi-Metal 5-piece kit from Lenox is something that tore into wood faster, with more certainty , and with greater precision than any spade bit or traditional drill bit we’d experienced. We broke out these bits on a rewiring job for an old 1925 Colonial 2-story home. As you can imagine, there were ample opportunities to try out several sizes of bi-metal bits, and we were looking for something that could handle the near-petrified wood that this house was constructed with. After several days of use, we were sold.
