Premium Wet Drill Core Bits For Concrete And Hard Masonry - 10Mm Segment Height, 12" Drilling Depth, 5/8"-11 Arbor - Ideal For Wet Drilling Only Review

I Needed to drill through 8 inches of a granite stone for a 1 inch pipe. I kept cold water on during the drilling and the bit stayed nice and cool. It took some time ( about 40-45 minutes ) I bought an adapter to use with my drill but the threads were not long enough for the bit ( the Threads don't start at the top so 1 star deduction for that ). Luckily I also have a cordless Milwaukee grinder that fit perfectly. The grinder worked great and I was able to put a lot of pressure on it too…

Had doubts ordering a Core Bit from amazon. However it worked fine for heavily rock fill concrete and deck pan. 5 inch core no problem didn't phase the bit only scratched the paint a little. Solid long lasting bit appears! Used an adapter for a SDS plus arbor and it turn it fine through the floor we drilled a sleeve through.

I used it with a drill to cut through a foundation. I used a 2" x 4" jig to stabilize the core bit until it cut a grove into the foundation and it drilled smoothly, with the long barrel it also drilled straight through. I used some liquid soap to help reduce friction as it cut through several layers of brick, concrete, and masonry.The core barrel did jam with hard brick pieces which I expected. I had a metal rebar piece that effectively punched these pieces out and resumed drilling.

It worked, running it carefully with a heavy-duty 1/2" drill. Used water when I could to keep things cool, but some of the hole was bored thru concrete block, which was easy boring but not easy to keep wet without a hose on it. Bored that part of the hole "dry". Bought the expensive drill adapter and had no problems with that. Probably worth the money, guessing by reading the different adapter reviews. Be careful, there's a lot of force & torque on the drill & adapter. Let the tool do the work…

Drilled couple holes into 4 inch exposed aggregate concrete and it worked like a charm,Not that easy to handle, it’s big and little awkward with a large right angle drill but did not take long to get it under control.Do your self a favor and buy a matching wood hole saw bit and make yourself a templet out of a 2x6, it makes it 10x easier.Great products imoAlso supplier did nice follow up on products as well.

The customer post that recommended using a 1x4 or similar as a guide was the key. It kept the core drill from wandering during the start of the hole. It drilled two holes around my old diving board anchor bolts in 3.5 inch concrete without wearing out. I'm not sure how much more it has in it, but if I ever need it again it will still perform.

Drilled through 20" thick Pennsylvania ironstone wall for sewer line. Used plenty of water but the grit on the bit is almost gone.It was a tough job and worth the cost.It would probably really hold up well for standard thickness concrete.

First time working with such large bit. Heavy and durable. Make sure you ready for task ( I use cbd cream for my knees and elbows)) Otherwise you’ll suffer soaring!

Product worked great, for a fraction of a core drill rental I was able to use my 30 year old mid size makita drill to drill 24inch core into a stone wall to cement black fence poles in place. Fabulous deal!

This core bit went bad only after first 4” deep hole into concrete with no rebars of course I used water. Ended up buying new core bit locally. You get what you pay for.

Worked great, used with Hilton core bit drill, screwed right in. No issues at all! Can be affected by changes in surface texture or condition during drilling.

I drilled 48 holes through 6” of rebar reinforced concrete with one bit. There is only 10-15% left on the bit but it took a lot of abuse. Good quality, will buy again.

The bit is long lasting but very slow cutting. It was taking me 22 minutes to drill through 2" of terra cotta, I drilled 31 holes over 2 days. The husqvarna and hilti bits blow it away.

I'm planning on using some of the native limestone on my property to make a water feature that looks like a natural spring. I used this bit to bore through one that was about 8" thick and then chisel around it for practice before I work on the one I will install permanently. Driven with a Bosch SDS Plus hammer drill through a 5/8-11 arbor, I had no trouble going through it in 10-15 minutes. I did take it slow and kept a hose on it the whole time. You can see in the picture that the bit made a…

I thought I might have to get a hammer drill, but as I was getting it going with a simple battery-powered drill that's not made for anything like this, it was making real progress. So I just kept going -- pausing to wet the bit and to squirt some water into the hole. It cut through two cinderblocks no problem in about 20 minutes. I was really impressed. It didn't hang up at all.

Worked nice going through 4” thick concrete. Drilling can be slow and time-consuming, reducing efficiency on larger projects. Sprayed soap water to cool it down, since I was cutting up through a floor.

Just received the package,.I just don't know why the delivery guy had to drive his truck to my asphalt driveway to make a U-turn, by doing that left his tire scraped some of the asphalt off which messed up my New Driveway,.he could just carry the package,.UPS guy is lazy.

We have been using this for our business the past few years and it is consistent.we were told on average, we could get about (10) uses from it, but we use it about 20x and then replace.

I now own 4 different sizes of these core bits. I am using them to core through rock, so I am really putting them through the paces. So far, they have performed very well. However, and I'm not surprised, one of them stopped cutting. I found that taking a bastard file to it, I once again had a perfectly performing bit. So, keep a heavy file handy!

Worked awesome!. I drilled one hole through an 8” thick retaining wall and the other hole through 12” thick retaining wall. I would highly recommend this drill.
