Yet another example of cheapening what was a really nice set. In Home Depot, saw this set with a “New! Lower Price!,” now $34.99 versus $44.99. So I picked it up and immediately realized what HD and Milwaukee had done: they removed the 1/2″ drill bit and replaced it with an extra 1/16″ drill bit.So, are they good bits? Yes. I have them, use them, like them. Is a good value? No. They lowered the price ten bucks, but the difference between the cost of a cobalt 1/2″ and a cobalt 1/16″ is $11, so actually they raised the price by a buck and presented it as a better deal, hoping you wouldn’t notice.But I did. And as a result think just a little less of both brands.

Outstanding bits for drilling through hard metals. Worth the money.
Ali Barrows (verified owner) –
I purchased cobalt bits to drill stainless steel which these didn’t do as claimed. Otherwise they are a good bit.

Cuts through like butter
Cathryn Upton (verified owner) –
Drill bits cut through the metal posts on my gate like butter. Seem to be good quality, and a welcome addition to my bit arsenal.
Ena Luettgen (verified owner) –
Great Drill Bits.
Lemuel Abbott (verified owner) –
I had some cast iron to drill through, and it defeated my oxide-coated drills. These worked much better, although there was still an impurity that defied these. At least the drill did not overheat and deform. I definitely recommend these as a budget solution and good for drilling in harder metals.

It’s construction, quality and power justify its cost benefit
Dwight Kassulke (verified owner) –
When I got the set home I realized that the drill bit set has been used and returned. Not happy
Alba Wilkinson (verified owner) –
Useful and very organize

Drilled thru stainless steel effortlessly.
Derick Sanford (verified owner) –
I tried Black Oxide bits but they weren’t up to the task, then I tried Titanium bits but only succeeded in breaking the bit. I then went back and bought the Cobalt set and they got the job done in twenty minutes.
Jimmy Raynor (verified owner) –
I was drilling out rusted screws with cheap drill bits and they would break easily. These Milwaukee bits drilled great and did not break. Very pleased with these
Elbert Hahn (verified owner) –
cuts through hardened steel fasteners like butter… amazing!
Ursula Baumbach (verified owner) –
Amazing!! Extremely sharp bits that actually “pull” through the wood I’m drilling. Much better than my current inventory of drill bits. Cobalt all the way!
Tania Bernier (verified owner) –
Purchased under neighbor recommendation. It worked well drilling a metal strip. The company should make another set with all the small bit sizes Instead of the 3 big ones.
Kaycee Heller (verified owner) –
Super sharp long lasting bits. I use them every day.

Nice drill bit, as advertised
