DEWALT SDS+ Hammer Bit, Rock Carbide, 1-1/8-Inch x 16-Inch x 18-Inch (DW5469)

This thing is one heavy duty beast of a bit. It is well made and I expect to drill many more holes with it during its lifetime. The only downside of it has nothing to do with its construction, and everything to do with its size: this bit requires a serious hammer drill behind it if you want to get thru concrete more quickly. A regular Bulldog Xtreme drill will easily get you thru brick and block with no problem, but be prepared to spend a little more time than you do with a 1/2" bit when drilling thru poured concrete. If you need to do it often, it's probably worth picking up a heftier hammer drill. Aside from the physics associated with cutting thru a lot of material, this is a great product.

I needed a larger diameter (1-1/8") Bit to drill through brick. I don't have an SDS drill. I took a chance to use it with a Makita cordless hammer drill. It worked well, but obviously not as good as an SDS drill. I wouldn't want to use it for more than a few holes trying to penetrate concrete, I'd be there all day. This drill bit is designed for an SDS drill, but I only needed 4 holes drilled all the way through standard Modular brick measuring at 3-5/8" thick by 2-1/4" high and 7-5/8" long. So to sum it up, I drilled 4 holes through a depth of 3-5/8" It wasn't easy, but I did it. One thing to note, when chucking the bit in, you have to line it up in the chuck just right, otherwise it really wobbles. But it can be done.

This dress Diaz Masonary bed is perfect for 3/4 PVC pipe. We are Electrical contractors so it’s for electrical conduit or really any other conduit or a hole you need to make. I was surprised how quickly It went thru the 8” solid concrete block!

Bought this to drill a hole in my driveway to insert a small pole that holds one end of a retractable plastic mesh fence used for blocking off our driveway when kids are playing. It drilled through asphalt with concrete underneath like butter. Did exactly what I needed and arrived within 24 hours. Happy customer here! Did not rate for longevity or durability because I only drilled one hole. It appeared to suffer zero damage drilling through about 5” of asphalt and concrete.

Needed to drill thru 11" foundation on pier and beam house to install frost proof sillcock. Did a great job. Made in Germany. Even nicked some rebar and it took a small amount of metal out so I could keep going. This is the biggest drill you can get for an SDS plus hammer drill. Any bigger and you'll need an SDS Max which is a much pricier drill.

Nice bit. I used my Dewalt 120VAC 1/2 inch drill and bored through my 6" foundation. It took time as the drill got hot fast and I had to let it cool down often. If I had a heavy duty drill it would have taken a lot less time. It ate through the blue stone in the concrete with much less trouble than anticipated.

I got this for one job - use with a new hammer drill to make a hole in a fountain to run a new electrical connection. The old one had 120V line literally run in to the bottom of the fountain and secured with a (leaking) supposedly watertight connection. Glad I got rid of that before something bad happened! I used this drill to provide another hole for a safe 12 V line. It worked like a champ through about 16 inches of solid stone (I used it from one side then the other - fortunately was able to "hit the target" and line the holes up. After use, the thing still looks pretty new and I suspect if I need to use it again it will continue to work well.

Wow! Easily made perfect circles for the pool gate sleeves in seconds! Cut right thru 2.5 in thick pavers AND the concrete footer below. Only took about 15 seconds with a large hammer/rotary drill. Very impressive. Highly recommend.

Obviously when you start getting into the larger SDS style bits its hard to find the "Plus" series in the larger sizes as they usually become SDS Max size collets which is totally understandable. If you have a high quality SDS Plus drill, you can get away with larger bits. This is one of the larger style SDS Plus bits I could find that works perfect for running 3/4" conduit thru concrete with a little room to spare. Definitely a quality bit, and will last a lifetime.

Works ok with tile, concrete and cement. Used for 8 holes and still very sharp. A good SDS hammer drill helps this process. A little expensive but may be worth it in the long run. 4/5 star. Quick shipping helps

Great bit. It makes easy work through brick and concrete. I use it for running gas lines from inside/outside to outside/inside.

Does not start cutting easily. Made a mess of my brick before it grabbed and started to drill. Didn't give me a clean hole.

It might be related to the power for drills using this type shank but it takes forever to drill in bedrock. I gave up after about 2inches. I also accidentally bought x2 of these so now I’ve got two neat paperweights. I’d guess it might work well in something easier like concrete.
