Home Depot offers the Milwaukee 40-Piece Shockwave Impact Duty Steel Driver Bit Set, model no. 48-32-4008, for $19.97. Opt for in-store pickup to avoid the $5.99 shipping fee. That's tied with our mention from last week and the lowest price we could find by $10. It features custom alloy 76 steel construction, optimized shock zone geometry, and a carrying case with pull latch.
