Customer Reviews for Milwaukee 5/16 in. x 4 in. x 6 in. SHOCKWAVE Carbide Hammer Drill Bit

I drilled 7 holes with this, and it didn't even lose its edge! It also has a very interesting tip design.

Lasted for 9 holes, then the stem sheared off. The 1/2" bit needs a stronger stem.

The profile of the carbide at the tip of the bit is unusual. Milwaukee claims it provides extended life and faster cutting speeds. In my experience the bit is very fragile. After less than 50 holes in cinder block the carbide on one side of the tip had failed and the bit was no longer usable. I will not purchase this Milwaukee product in the future

Very disappointed with this bit after reading the rave reviews. I drilled 4 holes and then decided to use water to help keep the bit cool but, alas, it was too late, the damage was done.

It was easy to drill the ceiling where I installed my ceiling fan.

bought this about 2 hours ago and on the third whole I started drilling it was done

[This review was collected as part of a promotion.] This drill bit is longer than my other bits of the same width (1/4") It's great it's longer. I think maybe they are skinnier for concrete because concrete will kinda dust as you drill while wood doesn't. It fits in easy and well into my drill which is a Milwaukee quick release type, so that's all that matters, since I eyeball the drill bit needed for any given scenario anyway.

[This review was collected as part of a promotion.] Perfect to screw into concrete. Very strong and didn’t have any problem using these. I used them to screw down zip ties for cords I used while running watering lines for my plants. Milwaukee is an amazing string and dependable brand.

[This review was collected as part of a promotion.] 7 piece Shockwave Carbide Hammer Drill Bit Kit is a great addition to our tool collection. Different sizes for every type of job. The bits are strong and durable which made it easier to drill into bricks and masonry. The strong plastic holder keeps from misplacing the drill bits. These our a must have for your tool collection.

[This review was collected as part of a promotion.] I like the look of it and the red is a nice fit with the Milwaukee brand. The bit fits nice into the chuck. There was no wabble when driving. It holds up well when driving into wood. Overall great bit.

[This review was collected as part of a promotion.] I have a drill. But this drill bit is something that must be in all tool boxes great for drilling holes in concrete especially cinder blocks and bricks. It works amazing easy to use and I look forward to purchasing more from Milwaukee tool brand.

Best and easiest drill bit I have ever used for concrete block. It cut like a hot knife through butter. I will never buy another brand - this drill bit is a gamechanger for me.

Used this to install some 12mm anchors in a concrete slab. Next time I would probably use a 1/2-inch, instead of the 7/16-inch. This bit, in my Milwaukee M18 Fuel hammer drill made short work of installing the four anchors.

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 bit with 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!

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.

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.

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.

I needed to put some holes in the bottom of one of my wife's clay planters. These drill bits worked great. The first drilled right through the pot while not cracking the clay. I then use the 1/8th size bit to increase the size of the hole. Now the water can come out of the bottom with ease. I also tried these two bits on a concrete slab I had poured for a base to a shed kit I got from Home Depot. I had previously ruined several older concrete bits, while drilling holes to secure the shed base. These bits went right through the concrete with no issues.

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.

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.

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.

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.

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'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.
