Home Depot offers the Milwaukee Shockwave Impact Duty Red Helix 23-Piece Titanium Drill Bit Set for $19.97. Choose in-store pickup to avoid the $5.99 shipping fee. That's the lowest price we could find now by $7, although we saw it for $3 less in November. It includes 23 bits of varying sizes, each with a titanium coating and 135° split point tip.
