This set sucks. Also drill bit holders are terrible rubber that make extremely hard to pull bits out

Have these. Agree with everyone else that the actual bits are fine, but the rubber holders are awful. I'd buy this set again in a second if it came in a better case/holder config.

The Brad Point Drill Bits are worth the 24 bucks alone decent deal.. in my opinion. But am holding out for Costco to drop the price

Good find. Why Costco over Amazon?

Ordered mine via Costco because I am tired of Amazon third parties and return policies. If I do not like the product, I can walk in and return it at Costco.
