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.

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.

Purchased these to drill through steel tubing and plate. My titanium bits would break or would take forever. These cobalt bits go through with ease. Would definitely buy again!

Does the job but be prepared to buy more bits. Don’t last as long as expected.

I purchase a nailer at the Lantana and jog HD, it was a little too heavy and bulky.. so I went back to exchange it for Milwaukee nailer that’s in the Father’s Day add.. only to be told the nailer was not available in any stores until June 24th.. I was a little upset about the fact I getting the run around, I walked away toward the exit door, that’s when Scott walk up to my face saying I could not walk thought this door. I asked him to get out my way, while walking away, I overheard him saying to another customer (that’s why people don’t like his type) I love shopping at HD.. I‘ll just take my business elsewhere. Great product, crappy service.
