Review on 🔧 Lenox 30881 VB1 Vari Bit 8 Inch 2 Inch - Ultimate Drilling Power and Versatility! by Scott King

Ideal for sheet metal work. Cuts holes quickly and evenly. Saves me a lot of time instead of using a few smaller regular bits and moving on to a larger one to keep the hole round. I've found it helps if you use a hammer drill and a non-slip metal drill bit, and use oil to keep the bit's tip cool.
