Home Depot offers the Milwaukee Shockwave 35-Piece Impact Duty Driver Bit Set, model no. 48-32-4001, for $14.97. Opt for in-store pickup to dodge the $5.99 shipping charge. That's tied with our mention from a month ago and the lowest price we could find by $17. These heat-treated steel bits include Philips, hex, flat, and square bits in varying lengths with three extension bits.
