This Milwaukee 5/8 in. x 16 in. x 18 in. Carbide Hammer Drill Bit is advertised for Concrete, Stone, Masonry Drilling but is labeled on the package “Concrete”. It is a 2-cutter bit and eats into concrete like wood bits drill into wood – that is with ease. The 3 flat drive end Is very effective at eliminating movement in the drill chuck. I used to buy another brand but my son gave me a Father’s Day gift of Milwaukee drills for an upcoming project and I was amazed at the difference in both the way they progress and life expectancy. I used this with my Milwaukee M18 battery powered hammer drill to drill through my 12-inch-thick foundation wall with excellent results.

The Milwaukee 7/8 carbide hammer drill bit is a durable and quality bit. It tackled brick and block with ease. Drilling a fast, clean hole with a cordless hammer drill. This drill bit was drilling through block without the hammer function. The drill bit did not bend or break when it was wobbled around the hole. The flat edges on the bottom of the bit create a positive lock in the drill. Made in the USA,

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 concreteI included some pictures to show the quality of the bit. I hope you like this review.

This is a heavy duty, well-built and designed Carbide Drill Bit from Milwaukee. I have a project coming up next month that will require my drilling into cement and I saw this as a great and helpful addition to my tools for that and future projects ….. One of the best features of this bit is the three-sided shank for improved grip… I do expect this to deliver the performance and longevity Milwaukee states because of my prior, positive experiences with Milwaukee products.

Milwaukee, always the best design, best material, and best production under the stars. But I am a bit biased, been a fan of Milwaukee since they where made here in the states, even with external production, their products ie: drill bit, meet and excell the competition. Plus the look of their red has become synonmous with quality, and can be seen redily on the job site. Packed well. Love the hex shank………………………………..

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 bitwith 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!

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.

I picked this bit up for a tile project, to drill holes in cement board in the shower and bath. It is not a real demanding job for this tool which is professional grade. Using a standard drill, rather than the hammer drill it calls for, it punched a hole in 1/2 inch cement board in about a second. It should last a long time, it feels very heavy duty.

many reviews are saying a few inches for this bit, but ill say that i had to drill 12 holes about 8″ deep in a solid concrete wall to stick my fence post braces into. wow did this tear through like butter.

This bit made it through a total of 17″ of 30 year old concrete with no problems. The same size bit from Bosch only made it 4″ into the same concrete before becoming too dull to use.

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 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

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 addition to the tool bag. With most bits in my possession, I always prefer to drill a pilot hole into the material first, for two reasons. First, smaller bits are cheaper than larger ones. Second, by drilling a smaller hole you create a little safety net in case the hole is off a bit or in case you hit a hard object that will deflect the bit. This 1″ bit is packaged nicely with the flutes painted, thereby delaying oxidation of the surface. After drilling my pilot hole, I switched to this bit and continued. it makes nice consistent holes for your project!

The Milwaukee 5/8” Carbide Hammer Drill Bit, part number 48-20-9042 in my professional opinion seemed plenty adequate to bore through a 10 year old 4” thick concrete block. We utilized the Milwaukee M18 FUEL 1/2” Hammer Drill/Driver, part number 2804-20 to power this bit and this drill had more than enough power. Now, if we were drilling through concrete thicker than 4”, a larger drill with a hammer feature would have been utilized for efficiency and user fatigue.

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.
