This product is what I exactly needed. For the job I was doing, I needed more durable bit. These bits from Milwaukee were strong enough for the job and more.

Good

Used to drill into stainless steel table so we could add a shelf. Got the job done and the bits are still good for the next job.

I was not impressed by these bits, at this price. I couldn’t tell any difference from the cobalt and the less expensive titanium bits.

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.

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!

Have used them on aluminum projects and always use light lubricating oil when drilling. They work great and have stayed sharp!

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 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.

Mixed reviews on these Milwaukee Cobalt Drill Bit set. I’m a Milwaukee brand loyalist. Drilling started out okay but was disappointed with the final result. Using a drop of oil to keep them cool while drilling through a 1/4″ thick Austrian made metal pitchfork shank. I was using my Milwaukee 3/8″ Magnum Drill going slowly and I decided that I didn’t want to damage the drill bits with no metal shavings coming out with the drill bit already 1/8″ into the metal…so I stopped !Going to try another well respected brand to possible finish up the job. Not sure if the Milwaukee bits were already damaged or not. This will not deter me from buying future Milwaukee products…just a bad experience with these Cobalt Drill Bits.

Cut through cast iron with ease. Excellent
Waldo Volkman (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.

Needed to remove a metal screw that had damaged head and the drill bit made it happen in record time for me.
