Lisa Bruen (verified owner) –
Bought this set to drill a couple of holes in stainless steel – it got the job done, but not without breaking off a tip or two (drill motor at lower speed with proper pressure). I contacted Milwaukee customer care who rectified the issue immediately and shipped out a new set in record time. I will absolutely be purchasing Milwaukee products again!

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.

Have used them on aluminum projects and always use light lubricating oil when drilling. They work great and have stayed sharp!
Gerry Bode (verified owner) –
Heavy duty drill bits. Use with cutting oil, and they will last a long time.
Della Kemmer (verified owner) –
The drill bits work great!
Rashad Howe (verified owner) –
Hizo el trabajo más fácil
Eleonore Christiansen (verified owner) –
I have used some of these bits in the drill press and they sink in the wood beautifully, nice clean holes. I have not tried metal drilling – I use my old “disposable” bits for that abuse.
Mia Nitzsche (verified owner) –
Excellent high quality cutting. Just wish I would have had the money for a larger more inclusive set.
Vickie Hansen (verified owner) –
Cobalt drill bits worked like drilling steel like butter . Titanium did not work on the project I was working on.
Erwin Sanford (verified owner) –
Very strong bits. Cuts hardened metal well.

Guadalupe Feil (verified owner) –
Did an excellent job of drilling out a broken exhaust stud on my air cooled engine.
Elliott Bode (verified owner) –
sharp
Jaylin Gerlach (verified owner) –
Very sharp cutting surfaces. Outlast all previous sets of bits I have used previously. Only difficulty is that they fit the case so tightly, it is hard to get a bit out. Because of their sharp edges, I used a tissue to grasp each one as I needed it.
