Amazon offers the DeWalt 9-Piece Standard Electricians Bi-Metal Hole Saw Kit for $44.99 with free shipping. That's the lowest price we could find by $7, although we saw this for $4 less last December. It includes 7/8", 1-1/8", 1-3/8", 1-3/4", 2" and 2-1/2" hole saws, small and large quick-change mandrels, and a carrying case.

Note: This item usually ships within 1 to 2 months.
