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.

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 big boy was the star of the show. Could not have asked for more. Money well spent.

We needed this bit to drill drain holes in our concrete floored chicken coop. It’s heavy duty and works well with little wearing on the bit. It does require a high speed drill and lots of strong pressure to get through concrete. It drilled through he floor fine after some sweat, so my wife tried it to chip away at a concrete column we needed to sculpt down. The third photo shows some of the effects of that. She was able to do it with this bit, but she did have to rest often.

Bit cut into concrete like butter

I occasionally need a concrete masonry bit for various projects and wanted to have this Milwaukee hammer drill bit for the next project. This 1” carbide hammer drill bit can be used for concrete, bricks, and cinder type blocks. This bit bores a 1’ diameter hole and has an overall length of 6”, including the 4” cutting portion. It is sure-grip, with three flat sides on the shank, which prevents slippage of the bit. It is good quality.

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.

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.

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.

Milwaukee comes through again. At a great value point.There is a rectangular deck on the front of our house that is bordered on and, attached to faux stone covered stem walls. Aka “stucco stone”. There is a large decorative fountain outside the front wall.I was replacing the old deck due to dry rot. Since I had the old deck completely torn out, I decided to add an electrical outlet and a water connection on the face of the wall for the fountain. The fountain had been on an extension cord and I had to fill it with a hose since before we moved it. Adding these features meant drilling two holes from the backside of the faux stone. Not a particularly difficult task.But, I didn’t have any masonry bits the sized I needed to accomplish this. And, I really didn’t want to spend what I assumed to be $40 to $50 for a new bit for this single use. Then along came this Milwaukee offering at under $20. I’ve never gone wrong with Milwaukee so, I picked one up.I was able to effortlessly drill the holes I needed using my hammer drill and this bit. It drilled right through the light metal flashing without the point walking away. The whole is very clean through several layers of material. There are some future uses I can see applying this ½” bit to in upcoming projects after all. I’m glad I got it.To give you an idea of the capabilities of this bit, when I drilled or, attempted to drill, a hole on the back wall opposite from the face wall, so that a water pipe could pass through, I ended up drilling 6” or more into a solid concrete step on the outside of the back wall that I miscalculated the relative height of. The bit wasn’t coming through although it was buried up to the arbor before I realized I had drilled right into the side of those steps!

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.

The Milwaukee 3/8×18″ 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 is long enough to drill through a regular block. 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,

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 7/8” Carbide Hammer Drill Bit, part number 48-20-9048 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 adequate 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.

Bought this bit to go through brick mortar and brick. It worked much better than anticipated. Key to success is dipping the bit in water to cool it off every few minutes and patience.

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 1/2″ long hardened carbide drill bit from Milwaukee, is perfect for masonry and harder surfaces, such as granite. It is the perfect concrete carbide drill bits for all concrete / masonry use, including granite rock. The hardened steel bit is sharpened for easy starting into hard masonry use. Drills easily into brick, block and tested on harder granite stone material, where this bit didn’t wobble, and easily drilled a clean hole. The long shank is a added convenient feature making this product easy to use.
