Used the small bit and worked well for drilling into brick. Wish I had a hammer drill – would of likely worked better. Did 4 holes and was able to use the concrete screws I needed to install.

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.

Excellent set of quality bits. The bits have 3-flats on the shanks which keep them securely set in the chuck. There is a very helpful “center point” tip which allows for precision drilling. As others have mentioned, let the bits do the work to preserve the carbide tips. The bits have held up well, with no signs of dulling, but just in case, the set of 7 bits does include 2 each of the most popular ones, 1/4″ and 3/16″. They are made in Germany. I would highly recommend them.

I highly recommend these bits. They seem to drill really fast and last a long time. I like this set of five bits from 5/32-3/8 inches as a set for a DIYer like myself. You buy one set and it should be effective for most jobs. The other thing I like about this set is the bits are 6 inches in length. Most of my other bits in this size range are only 4.5-5 inches in length.

These are some of my new favorite bits. The absolutely punish the concrete that you are drilling through, and they do it fast. I drilled hole, after hole, after hole with these, and not one issue with dulling or breakage. I also love how the flutes take the dust up and discharge it rather than bogging down the the bit. I have to say I am very pleaded with this bit, and for the price, you absolutely cant go wrong.

I have several sets of Milwaukee drill bits, and this hammer drill set is no exception to the excellent quality of Milwaukee bits. Drilling in concrete block is easy, and even into solid concrete doesn’t dull the bit until after 8-10 holes, compared to only a few holes with a non-carbide bit. Sharpening the bit restores the cutting quality, as it does most all drill bits. This kit includes the most popular sizes in a plastic box.

I drilled a 1/8 thick piece of mild steel plate and the bit worked as advertised. I am very satisfied with the bit set. Thank you HDX for a quality product.

The Milwaukee drill bits worked better and drilled holes faster than my other drill bits and had a longer life. Living in a CBS house with a concrete seawall I do a lot of drilling for fasteners. Now days Tapcon screws seem to be the fastener of choice and in order for them to hold the hole has to be the correct depth. I usually start with a small drill and work up to the bit I need. To test these I went right to the 3/8 size. Using a corded hammer drill it drilled right thru the concrete to the depth I needed. The bit is squared on three sides to prevent it from slipping in the drill. I spent a lot less time drilling and got the job done quicker. Another quality product from Milwaukee.

I’ve only used the bits once, it was in red brick. Seemed like it was hard to get drilling for first 1/4” or so for each of the 6 holes I drilled. I was using an M12 Fuel hammer drill set to hammer. Once last that 1/4” though bits drilled fine.

The Milwaukee 6 piece Hammer-Drill Bit Set contains the most commonly needed sizes of hammer-drill bits. Whether you need to drill a hole in concrete, concrete block, brick or masonry, these bits will easily do the job when paired with a hammer-drill. The bits have a total length of 6 inches and are carbide tipped for long lasting durability. Sizes range from 1/4 , 5/32, 3/16, 5/16 and 3/8 inch. There are two ¼ inch bits giving you the total of 6 hammer-drill bits altogether. One important thing these bits have is a 3 flat shank design to give the hammer-drill the best grip on holding the bit tightly. If the bit was round, then the hammering action may cause the bit to slip. These bits are designed to be used in both corded or cordless hammer-drills.On the downside, the only thing I didn’t like with these hammer-drill bits was how hard it is to unpackage them. I literally used a tin snips to cut the top off and had to be very careful so as not to damage the bits since there is not much room in the packaging when trying to break it open. I’m sure it was done as a part of theft protection while its displayed in the store, but I would like to see more thought given on how a consumer is going to get these drill bits out without going through a lot of work. I don’t know what the answer is, but it is very inconvenient as it stands right now, hopefully it will be addressed in the near future. Other than that, they work incredibly well, I had no problems drilling through concrete with these bits.

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.

Like buttah. These cut through and old foundation like butter.

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

This drill bit set has the same size bits as Milwaukee # 48-20-8851 (THD SKU #525593) but it has one extra of the 3/16 and 1/4 bits. The bits are nicely crafted. I’ve used the 1/4 and 3/8 bits to drill holes in concrete for anchors. With my hammer drill, the bits bore through the concrete like it was a piece of pine.I’ve found the plastic case they come in to be surprising useful for storing the bits. I used a sharp knife to to cut the plastic wrapper right where the bottom edge of the top half the of case ends, right in the middle of the words Larga vida on the wrapper.The bits were made in Germany.

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.
