        Q:What percent cobalt do these Cobalt Red Helix drill bits contain?
        by|Dec 17, 2022
        2 Answers
        Answer This Question

        A:  I believe they are M35 which makes them 5%. And the cobalt is throughout the HSS which means they can be sharpened, BUT THEY ARE BRITTLE. Use at 200 to 300 rpm

        by|Jan 20, 2023

          A:  Cobalt is generally a hard facing material, not an alloy

            Broke on 1st use on aluminum
            Tried to drill a 5/16 inch hole through 1 in. Square aluminum tubing. The bit broke in half. CHEAP!
            by
              I wasn’t impressed
              I paid top dollar for these 40!It did help to bite faster an prevent some walking. The double tip isn’t present on the smaller bits so they aren’t designed with the same technology so that’s no good. I was drilling some angle iron an running it hard had them literally explode in my face it was the two big bits be careful

                These are awesome, but dull faster than I wanted
                I have used these a lot and I honestly wish they would stay sharp longer. They work well for drilling into aluminum and non-hardened steel, but after any drilling into any metal they start to dull quickly. I learned that using them at slower speeds works better and keeps them sharper, but still for the price I thought they would be a lot better than the Shockwave bits from Milwaukee. Not a huge improvement in my opinion, but still a step up.

                Great set of drill bit
                This set of cobalt drill bits by Milwaukee are perfect if you are looking for a bit to got through metal, cast iron, or wood. The bits have long life when using in either of the materials and makes a nice clean entry and exit holes. The set comes with 6 bits ranging from 1/16 to 5/16. Each of the larger size bits have the quad edge tip that allows it to stay sharper longer. Overall a nice set of drill bits that I would recommend.

                Amazing for mild steel, harder steel
                This is a fantastic set if you are doing a lot of metal work with mild steel that can be found at many metal shops. I found these new helix drill bit, with these new Spiralized tips, can punch through mild steel like a hot knife through butter. I usually have a little bit of trouble punching through mild steel even with the best bits, if I’m not using my drill press. But these make it super easy to use a regular drill punch through any moderate depth of mild steel. I’ve gotten up to an inch and a half of penetration on very thick mild steel pretty easily. Use tap fluid or cutting fluid and it will be even easier. Great set.

                Quality set of most used bits
                Milwaukee Cobalt Red Helix Drill Bit Set for Drill Drivers (6-Piece) Includes 6 RED HELIX Cobalt Drill Bits (1x 1/16", 2x 1/8", 1x 3/16", 1x 1/4", 1x 5/16"). I really like that these are also rated for Hard Metal. I will only be using these bits on wood so they will last a very long time. The 1/16" bit is strong and i can drill angled holes for when i and needing them for my scroll saw. The only thing that could be better is a tray to hold the bits.

                Great for hard metals.
                The Milwaukee Cobalt Red Helix Drill Bit Set for Drill Drivers comes as a six-piece set consisting of one 5/15-inch bit; one 1/4-inch bit; 3/16-inch bit all with the Quad Edge Tip and two 1/8-inch bits and one 1/16-inch bit with the regular edge. When drilling stainless steel use a slow speed so not to heat up the tip. The larger bits have an easy start tip which helps prevent the bit from sliding when you start drilling. The bits can also be used in soft metals and wood. The 3 larger bits have all have 3 flat surfaces on the shaft that prevent the bits from slipping in the drill chuck. The bits last up to 15 times longer than Black Oxide bits and the Quad Edge tip stays sharper longer.

                Sharp and Durable
                The Milwaukee Cobalt Red Helix drill bit set is extremely sharp and durable. I had purchased a cheap set of drill bits some time ago and after a dozen or so uses, were so dull they literally would not even drill through wood. I have used the Milwaukee bits about five times now and they still perform as well as the did the first time I used them. The set contains 6 bits, 1/16, 1/8 (2 pieces), 3/16, 1/4 and 5/16. The bits have a flattened edge in three spots along the base of the bit to prevent twisting within a drill. According to the manufacturer, the tip has a quad edge that stays sharper longer and the bits are made from Cobalt giving 15x more life than black oxide. I am very pleased with the performance so far.

                Sharp bits with excellent debris removal
                This drill set is performing extremely well in wood and metal. The special 'quad edge' sharpening is supposed to keep them sharp longer, we noticed, that the small inner bit appears to locate the bit before the full size diameter makes contact. Debris removal in 1 1/2" wood is excellent and the larger diameter drills have 3 flats machined on the shaft, which helps to lock the bit if the drill chuck does not lock well any more. We can not comment on durability, but as received they are excellent.

                good drill bit
                First of all the bits are more expensive than just standard off the shelf bits, but when looking at how long they last and stay sharp when drilling metal the end price is cheaper and a whole lot less aggravating. The end has three flat sides for secure holding in the chuck. set includes 6 bits 4 of which have the Quad edge tip. Starting slow they do not have a tendency to walk. and in a deal press just go right on thru 1/4 in steel.
