Home Depot offers this Titanium Drill Bit 115-Piece Set, model no. PSO7535, for $29.97. Opt for in-store pickup to dodge the $5.99 shipping charge. That's the lowest total price we could find by $6, although we saw it for $2 less in May. It features SAE bits up to 1/2", 60 wire gauge sizes, and 26 lettered sizes.
