Longer but skinnier
[This review was collected as part of a promotion.] This drill bit is longer than my other bits of the same width (1/4") It's great it's longer. I think maybe they are skinnier for concrete because concrete will kinda dust as you drill while wood doesn't. It fits in easy and well into my drill which is a Milwaukee quick release type, so that's all that matters, since I eyeball the drill bit needed for any given scenario anyway.

    Works great!
    [This review was collected as part of a promotion.] This drill bit works great. I make tumblers and this drill bit came in handy to drill my holes so I can string lights on it! It made a smooth hole! I have nothing bad to say about this product! Will be getting other sizes!

      [This review was collected as part of a promotion.] I like the look of it and the red is a nice fit with the Milwaukee brand. The bit fits nice into the chuck. There was no wabble when driving. It holds up well when driving into wood. Overall great bit.

        [This review was collected as part of a promotion.] I have a drill. But this drill bit is something that must be in all tool boxes great for drilling holes in concrete especially cinder blocks and bricks. It works amazing easy to use and I look forward to purchasing more from Milwaukee tool brand.

          I don't use concrete bits on a daily basis, but when I need one, I want it to remain sharp and to do a good job cutting. I've used the cheapo bits and it doesn't make sense to save a few dollars, but to have problems finishing the job. This Milwaukee Carbide Hammer Drill Bit is a nice high quality bit. The carbide is nice and sharp. It's well ground and the welding is great! The flutes are clean and well cut. It's made well and will last a very long time. I highly recommend this drill bit if you need to drill through tile, stone or concrete I included some pictures to show the quality of the bit. I hope you like this review.

          I was eager to try this Carbide Tipped Hammer Drill bit in my latest project: splitting large granite boulders using some Wedges and Feathers. The product comes nicely packaged and with a flare of red striped paint. Package notes it is good for Concrete, Block, and Brick. However, description of item says it is for "Stone and Masonry" so I thought it was the right bit for my job. I gave it a whirl in my hammer drill and the first three holes went very quickly. In the fourth hole it seemed I had hit a brick wall (no pun intended). The tip of the bit got very hot and started smoking from excessive heating. Basically it was toast - see the picture of the tip after my drilling. Maybe I went at too fast an RPM - the package gives no advice on drilling speeds. Overall, I give this 3 stars for initial performance and likelihood that it would have better longevity when used for drilling into concrete block or brick. But if you plan to drill into natural stone such as granite, not sure it will go the distance.

          Great Drill bit! I’m beginning a project to put a new door on my cinder block storage building in the back yard and this bit goes right through the cinder blocks with no problem whatsoever. The bit is 12” long bit with a usable 10” length. It is 1/4” in diameter. I use this with an inexpensive single speed hammer drill. There are instructions on the back of the packaging indicating this bit should be used on high speed for concrete, brick and cinder block. The length of the bit allows for installing bolts all the way through the cinder blocks for extra security. Out of curiosity, I tried the bit on a brick and some concrete. While slower at penetrating the brick and the concrete, it did a good job of penetrating both. This bit does a great job!

          The ideal drill bit to go through wide concrete walls! We got a new DIY MRCool AC unit and I had to drill the hole for the piping to go through our outside wall. I needed a 3 ½ inch hole, but the rental companies only have the round numbered ones, and I did not want to spend $100 or more for a hole drill bit that I would use only once. So, my next option was to get a concrete drill bit and make several holes in a circle in the size we needed. And having a long concrete drill bit came in handy, so instead of doing the inside hole and then the outside hole, I was able to do both at the same time, shortening my task. The drill bit quickly cut into the concrete with no skipping or wandering off the target. The 3-sided shank helped keep the bit locked into the drill, so no slippage. Having used another smaller concrete drill bit first, I noticed the speed was immensely quicker with this drill bit. I was amazed at how fast and efficiently this bit cut through the concrete, almost effortlessly. I did not have to press it into the concrete, like some of the others.

          This is a great bit for drilling in concrete. It's length makes it ideal for almost any project, and its edges are very sharp, making for fast work. It's very efficient when paired with a Milwaukee hammer drill, and it produces clean holes. Obviously, the combination of its length and weight means that it will throw off the balance of your drill when not in use & it won't stand up on its own, but that's to be expected. Overall, this is a well made, top-notch carbide bit that should last a long time.

          This 3/4" carbide bit from Milwaukee has a sharp tipped edge, making it easier to drill hard concrete, block and even rock granite. This drill bit can be used with a hammer or impact action. The sharpened tip allows this 3/4" drill bit to easily start into hard surfaces with no wobble, and makes drilling larger bit projects easier. Highly recommended for larger hole applications.

            The 1 inch by 4 inch long shorty drill bit is mainly used for concrete but I had to use it for concrete blocks. I was installing a gas pipe for a BBQ grill and found the smaller hole wasn't quite large enough for the new pipe. It is tough, sharp and powerful making easier work for large holes. I have also used it for concrete surrounding wood posts sunk in concrete. Great job for this tough little giant. Carbide will last a long time.

            The 7/8 inch carbide drill bit came in handy for drilling concrete blocks. I had to add a gas pipe for a BBQ grill so you drill where you need the pipe. This drill bit is extremely sharp and makes short work of drilling concrete, especially when you use a M-12 Milwaukee drill to bore those holes. I have also used the bit for drilling bore hole in removing posts in concrete. This thing is 10 inches long for deep holes. Love the drill bit.

            The Milwaukee 3/4 in. x 10 in. x 12 in. Carbide Hammer Drill Bit makes a 3/4 inch hole in concrete. It has a carbide tip to drill into hard concrete, brick, or cinder block, has a 10 inch long cutting bit and a total of 12 inches long from end to end. The shank fits into a hammer drill with a 3/8 inch shank. This bit is advertised to have 5 times the life as ordinary hammer drill bits. The carbide tip is sharpened in a fluted shape to remove the dust from drilling. This is a very nice, durable hammer drill bit. Cuts through cement quickly making a clean hole without wavering.

            The Milwaukee 1/2 X 16 inch by 18 inch carbide Masonry drill bit is a beast, I used this bit on my cordless Ryobi hammer drill to attach brackets to old concrete steps to connect my wooden deck, the carbide tip of the bit reduced all the dust as the bit tore deeper into the concrete. It was like a hot knife going through butter. The bit worked swiftly as I didn’t need to change batteries half way through the project. I’ve used smaller masonry bits, but this one by far was the easiest to use

            This bit will fit in any electric drill that has a standard three-eighths-inch Jacob's chuck, but for decent drilling speed you must use it in a hammer drill. I used this bit in a old hammer drill that I have had for years. For a bit of this diameter I found it to be surprisingly fast. I didn't actually time it, but it seemed like it took much less than a minute to drill completely through a concrete slab that was five-and-one-half inches thick. It should be even faster in concrete block or ordinary clay brick. In new condition it has very sharp, machined cutting edges and should even cut through rebar pretty quickly. So far I have not been so unfortunate as to hit rebar. On inspecting the bit after drilling a few holes, I found chips in the cutting edge (see photo). Once the edge is chipped I would not expect it to cut through rebar as well as before, but it seems to continue cutting plain, even hard, well cured, concrete just fine. I may buy a second one of these and reserve it for times when I come up against rebar.

            This ¾ inch Milwaukee Carbide Hammer Drill Bit is made by a company that has been a leader in the industry since 1924. My biggest issue with drilling into concrete or bricks is the bit slipping in the drill chuck. That shouldn’t happen here with the 3 flat sides on the grip. The wide flute will quickly push the debris out and help reduce heat. Like all Milwaukee tools, I recommend this bit for the DIYer or professional use.

            First…this is a three flat shank bit suitable for use in hammer drill with a three-jaw chuck, not directly in a SDS Plus or Max chuck. They do make three-jaw chucks with SDS shafts, which is how I used the bit to drill into concrete and concrete block effortlessly using two different hammer drills—a corded Milwaukee and a cordless Ryobi. Drilling into brick took much longer. The new bit drilled smoothly, and the point stayed in position as the holes started but the hole in the CMU drifted and created an oblong hole—probably due to the material and not the bit. The flutes are much wider than some other bits—see comparative photo—which allows the dust to flow out of the hole without binding. The ”1” X 10” X 12” (25.4 mm X 254 mm X 305 mm) designation refers to the diameter, the nominal length of 1-inch diameter portion and the overall length of the bit from end to end. The flutes end 9-inches (228 mm) from the tip. This allowed me to drill through an 8-inch CMU with no problem, and I believe that the bit could handle a 10-inch block. Drilling through solid concrete looks limited to the 9 to 10-inch range with proper clearing of the hole. The shaft of the bit is reduced to fit in a 3/8-inch chuck. After drilling test holes through an 8-inch CMU and a brick and then 21 holes through 4-inch old concrete, the bit showed little wear except for some of the red paint near the tip—see photo. The smooth, red powder-coated flutes are a nice touch, but I cannot tell if they add to the functionality of the bit. The flutes are easy to clean and the paint should resist rusting. Alas, the “Milwaukee” bit is made in China.

            As a homeowner and DIY'er i haven't had a ton of experience with large diameter hammer drill bits. Typically I have used smaller bits appropriate for drilling expansion anchors into concrete or brick. Let me just say, this thing is a beast. The reason for needing the product was to relocate exterior spigots through our 2 wythe brick foundation wall. I was looking for a clean hole since previous installations done by other homeowners were very rough made it difficult to install the frost free assembly. This bit made relatively quick work of the wall and i was very happy with the result.
