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.

Awesome drill bit, even without a hammer drill it went straight through the concrete like nothing

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.

It works exactly as I need it

I’ve always had a 3/4 masonry drill bit in my hammer drill storage box. However, they never seem to hold up as long as I expect. I ordered this drill bit for two reasons: I needed a bit to drill completely through ten inch concrete block & I’m expecting this bit to last forever. That may be an overstatement, but my experience with Milwaukee, in general, has been excellent. I’m not sure how much faster (they claim twice as fast)I this bit can drill thru concrete block, which has concrete poured into it, but any improvement in the time required to drill a ten inch hole will be appreciated.

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.

Received product timely. It appears to be a great price for the item. Although the opportunity has not yet presented itself for me to use this particular drill bit – it won’t be long, I’m sure. Thanks.

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.

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.

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.

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!

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.

Worked great drilled thru masonary block with ease

The Milwaukee 1” Carbide Hammer Drill Bit, part number 48-20-9049 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 and was underpowered for this bit. Therefore, a step up in drill size should be considered for efficiency, user fatigue and preserving the life of your equipment. Great bit nevertheless!

I will be using this 7/8-inch bit in a standard (1/2″ drive) hammer drill. Being it is a Milwaukee designed bit I didn’t have any reservation that it would not work. Before using it in the field I wanted to see how it performed, how fast it would drill as well as dust removable. The 3-sided shank allows you to get a good tight fit on the bit. The third and fourth pics. below are close ups of the shank and carbide tip. The fifth pic. is of, probably a 50 yr. old piece of block. The sixth pic. is of a piece of 1 1/2″ concrete stepping stone, about 3 yrs. old. If you look closely you can see the difference in the dust from the two blocks. Standing above the two blocks and with little pressure it only took 5-6 seconds to drill a 7/8″ hole. Even though I only drilled about 3 inches, wiping off the tip it looked brand new. Concrete, block or brick, if you need a masonry bit from 1/4″ to 1″ you owe it to yourself to look at this line of bits.

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.
