For in-store pickup only and with stock varying by ZIP code, Lowe's offers the DeWalt 100-Piece Black Oxide Metal Twist Drill Bit Set, model no. DWA4CASETLW, for $24.97. That's $25 off and tied with our mention from last week as the lowest price we could find for a 100-piece DeWalt bit set. Sales tax is added where applicable. It includes 100 black oxide drill and screwdriver bits in four secure carry cases.
