ZERO STARS...Mixed packs of garbage
AVOID THIS BRAND!!! I've purchased several sizes of these drill bits. All of the packages are marked "Premium (Made in US) Industrial Grade Cobalt Drill Bit". They each do indeed have 12 bits, and they APPEAR to be cobalt (they are gold-oxide coated). However...one package of #31 bits has FOUR different manufacture bits in it. A second package of the #31 size bits has 12 bits which are all of the same manufacture, but different than any of the (4) manufacturers from the first pack.Some of the bits are marked "Drill America", which are Chinese bits. Some are marked U.S. Some don't have any markings at all, not even size stamps! Each package is different than the next, and a lot of the packages have 3 or 4 different manufacture of bits in them. Who knows who made these, what country they're from, what size they are, what kind of steel they are...waste of time and money. AVOID!

It looked like a great drill bit
It looked like a great drill bit . But -- the description didn't mention that it is not a 1/2 inch shank drill bit so I was unable use it. It was bigger than my drill - it was 9/16 inch.
