        Answer This Question

        A:  They only say cobalt so safe to assume they are m35. If they were m42 it would be stamped all over the packaging.

          Great quality
          I try to get Milwaukee brand tools every time I need tools. The design, workmanship, and ease of use is always present. This Cobalt metric drill bit set is the same quality I'm used to. This set features 19 bits ranging from 4.5 mm to 10 mm in .5 mm increments. The storage case is durable and designed well. I needed to drill pilot holes in my livestock trailer to mount new lights. The bit worked perfectly. Highly recommended!!

          only worked at first use to drill a hole in steel
          Only worked at first use to drill a hole in a steel bed frame. The second time to drill second hole, they behaved very differntly from the first time use, much slower than drilling the first hole. after finishedd the fouth hole, the drill head was damaged(see picture)

            Work well, but smaller bits are too short
            These bits work fine overall and it’s nice that I can quickly change between them in my impact or drill; however, the smaller bits are too short. With any standard 1/8”drill bit I can usually get through a 2x4. I can even do it with a 7/64” bit if I keep it light in the chuck. So that’s a flaw in my opinion. I’m glad they give you two of each for sizes 5/32” and below, but getting bits in and out of the case isn’t particularly easy.

                Terrible case design
                I have not even used the drill bits yet, but already hate the case. The set I ordered on Sep 21, 2023. The case is not a continuous hinge like is shown in the picture. It has 2 separate hinges with a finger sized gap in the middle. If you hold the case like I did you will hate it as soon as you close the case. As far as the drill bits go, I plan of saving these for light duty (no metal) so I don't break any.

                  Very sharp and quick acting
                  I just recently used the Milwaukee Cobalt Red Helix Metric Drill Bit Set for Drill Drivers (19-Piece) for installing some metal slide-out shelving in our kitchen cabinets. The 2.5mm bit was the perfect size for pre-drilling the screw holes for the frames. I was impressed by how quickly and effortlessly the bit bored into the cabinet. With 19 individual sizes, there’s a very gradual progression in diameter from one to the next, letting you find just the precise one for the job.

                  Bad Case of Labeling
                  If you're a seasoned woodworker who can tell the size of a bit just looking at it, maybe this set is for you. Otherwise, its case, with its 3 rows of bits, makes finding the right bit unnecessarily difficult. The large bit size markings are obscured by the medium bits. The medium bit markings are exactly where you'd expect -- for the small bits. The small bit markings are so far down, they disappear if you tilt the holder upright within the case. Such a poor design. Will return.

                    These really work for hard metals
                    I'm reviewing these Milwaukee cobalt red helix 15 piece drill bit set for hard metal, I'm a tool and die Maker with over 40 years experience, and for hard metals and hard stainless steel these drills work very well. I drilled hard 17-7 stainless steel as well as Spring temper 302 stainless steel with ease. With a normal jobber's drill trying to drill through the 17-7 will heat up the drill to the point of turning blue and damaging the end of the drill. These Milwaukee drills had no problem with it. The only issue would be once they do get dull it would be difficult to resharpen these with the kind of point they come from the factory.

                    Drill bits came in a nice case, but did not live up to my expectations. Drill bits dulled after first use drilling through soft steel. I used lubricant and used a slow drill setting.

                    Must Have for any Maintenance Tech!
                    Love this bit set! Being a maintenance technician at a large facility and always doing different tasks I have to have a good set of bits. I enjoy that the kit comes in a case and is arranged by size. They are easy to identify and grab and it makes my task at hand incredibly easier. I hate digging for bits and guessing if I have the proper size or not at the bottom of a tool bag. Never again thank you Milwaukee! I've used these a couple of times already and they fall nothing short of fantastic. I had to widen a hole to make a project work and the bit allowed me to do just that perfectly with ease and accuracy. It took seconds to do. Overall, I would easily RECOMMEND the set to anyone needing a good set of bits. I wouldn't want another brand other then Milwaukee!
