Used one of these bits to drill over 120 holes in mild steel. Used lots of oil and a drill press. The set is a good deal over buying bits separately and they double up on common sizes.

works great
I’ve had these bits for a couple weeks now and they have worked as expected on multiple types of metal. The case is very nice and functional. These bits are great at not walking when first starting and they get a good bite into metal. I haven’t had any break so far and they seem sharp still. These meet my expectations and I don’t have anything to dislike about them. Please hit thumbs up if this was helpful.

1/2 inch drill bit broke the first use.
I was drilling a hole in a pole to make a tether ball pole for my son. The drill bit broke before I could completely drill the first hole. I'm taking the whole set back for an exchange. Maybe I'll have better luck with the next set.

Excellent performance on hardened steel lugs
Used these to drill through and remove two wheel lugs that had rounded off and could not be removed any other means. Drilling through this material required slow drill speeds to avoid overheating. No cutting oil was required.The attached pics show the fantastic job done by the bits in cutting through the lugs and allowing them to be easily removed by snapping the tops off.

Seeds Program Review
(What's this)
The Milwaukee Cobalt Drill Bit 29-Piece Set is an excellent, comprehensive set of drill bits, with an extensive range of drill bit sizes ranging from 1/16 inch to ½ inch in 1/64 increments. The bits themselves are very well machined, quite durable, and have excellent material-boring capability. This week I used one bit in my electric drill to bore several pilot holes through a very dense hardwood, in order to subsequently install toggle bolts. The drill bit performed absolutely effortlessly, very quickly, and shows no signs of wear whatsoever. Today I used the 7/32 bit to drill a hole through 3/16” thick steel (see picture). Again, the bit performed flawlessly and showed no signs of wear. The entire set is contained in a strong plastic storage case, in which each bit size is clearly marked.

Seeds Program Review
(What's this)
Well-made & sharp drill bits. This sets comes with a handy case to keep them organized. The bits are very sharp and make quick work of drilling through anything. I was working on 2 different projects one was wood (2x4s) and it goes through like a hot knife through butter. My second project, I needed to enlarge some holes on some heavy duty casters and I was able to drill them out with ease. These are high quality drill bits and I expect them to last for years.
