Kmart offers the Craftsman 21-Piece Split Point Drill Set, model no. 32168411, for $6.99. Opt for in-store pickup to dodge the $5.99 shipping fee. That's $3 under our mention from two days ago and the lowest price we've seen. (It's also a current low by $15.) This set features a black oxide finish, which allows them to run cooler and last longer than standard drill bits.
Of note, Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
