Glad I purchased them.

Got the job done quickly with my m18 fuel hammer drill. No need for a sds hammer on smaller jobs. Not sure of long term reliability yet.

With the 1/4” sized bit my hammer drill easily penetrated a one inch deep hole in my concrete patio in less than fifteen seconds! That was too easy! I needed the hole for an anchor so I could secure a D-ring for some netting.The bits come in a small, plastic, throw away package, but I would have preferred it if they came in something you could use for a simple, storage case instead. The size is engraved on each one for permanent identification. The shanks have three flat sides providing for a secure grip by your drill. These quality bits are made in Germany.

put a garden hose holder on the concrete foundation. The bits ate up the concrete. I had no problem.

Unusually small sizes but work perfectly…………………………………………………This is an unbiased review that is unaffected by the fact that I received this product for free. As proof of impartiality, just click on my nickname and see the average of the ratings I have given over 300 reviews to date.I don’t have many instances to drill a hole in masonry material smaller than 1/2″ diameter, but if I ever did, these would work just fine. I tried 3 sizes on an old red brick and the drills went very fast using a Milwaukee 1/2″ hammer drill. It took just a few seconds to drill each hole all the way through the brick. It went so fast that I failed to release the pressure near the end and the bit broke through the brick, taking some material with it on the bottom side. They should work better when I am used to going this fast.Each bit has 3 flats on the end to accommodate a normal 3-point chuck.The set comes in a clear plastic case.

Very nice set of small hammer drill bits, 5/32″ up to 3/8″. I have always preferred Milwaukee bits because they seem to last longer and cut better than some of the others I have tried. Included with the bits is a very handy plastic carrying case. The case also states ‘Made in Germany’, which may account for the better performance as compared to lesser brands.

Nice selection for the price. Drill bits work very well for drilling tile with a hammer drill.

I’ve used plenty of bits only to have them break or warp after the first couple uses but the Milwaukee team has out done themselves with this one. I’ve used these over and over and have yet to break or warp any of them.. THANK YOU MILWAUKEE

Durable and nice features in this set of Milwaukee hammer drill bits. First of all, it carries the Milwaukee brand name which is among the top brands for the professionals and even the DIYer. The bits are high quality and easily cut through the cement block that I used as a test. For a masonry drill bit, you can’t go wrong with these. Added benefits include the three-sided shank that will prevent slippage in the chuck and the thick plastic carrying/storage case – just be careful when initially opening the package that you don’t cut the plastic. Just cut the paper label where the upper and lower halves of the plastic case meet. Very nice set if you are looking for a multiple bit set to have in your toolbox.

A small set but a very useful and good set of hammer drill bits. Noteworthy items:• These are serious bits made for masonry and concrete applications.• The sizes included in this set are some of the most common used sizes. 5 different sizes of bits with 2 of the ¼ bits.• Carbide tips and overall construction will provide extended uses compared to many on the market. Keep in mind that all of these types of hammer drill bits have a much shorter life span compared to standard bits.• Price is fair for a set of this quality.• 3 flat side shank design to hold in place.• A nice hammer drill helps when using these bits to get the full benefits.With the exception of the tedious work it takes to unpack these bits, I couldn’t find any issues. It’s a nice little set and that anyone with a hammer drill will appreciate. Milwaukee is well known for their quality products. I fully recommend.

Perfect for hammer drills in tough material!

These are great bits and do not slip in the chuck. I mainly use them in poured concrete walls and slabs and they work very well.I will most likely purchase another set in case I ever wear these tough bits out.

The drills are as expected, and the shipping container can make a permanent drill holder

Excellent service and the bits are strong for concrete work

Excellent carbide drills for brick, concrete block, plain and reinforced concrete. These 2 cutter bits eat into concrete like wood bits drill into wood – that is with ease. 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 have used these with my M18 battery powered hammer drill with excellent results. This package includes five of the common sizes used for concrete inserts and screws with two each of the most used 3/16” and 1/4” sizes in a handy plastic case.
