These drill bits are great. I needed to drill holes in my bricks to install 2 security cameras. I usually buy brand name masonary drill bits. In the past the brand name dulled very quickly and would need to use 2 or 3 for 1 hole. With these drill bits, I used 1 bit to drill 8 holes and it took hardly any effort. I recommend these bits highly. They get the job done quickly.

Amazing and hard. I was happy 😊. Working continuously with one. Maybe 6-10 halls on back splash did, and still working. Wondering.

I was setting up 2 shower doors. I went to hardware store and bought their only option and it took 3 drill bits to install 1 door in tile. I bought these and 1 completed other job.

I was burning through bits trying to put anchors in my concrete floor. I thought I would use up most of these but I only ever used one. Very good product for my project. Just get it.

I bought this 10 pack of concrete drill bits for job that required 8 holes into concrete about 3 cm deep. I haven't had much luck with drilling holes in concrete before without the bit wearing down after a couple of holes, so I fill anticipated that I would use quite a few of these. I was surprised that I got the first one done relatively easily, and it made it through to the 8th hole that I drilled. Granted, by the last hole it was getting more difficult, it still worked and I only ended up using the one bit out of the set of ten. This did the job for me and then some.Edit: I bought a set of brand name masonry bits (Bosch) and they weren't nearly as good as these ones. Very impressed.

These worked well with my Hammer drill but they are a bit short.

I was having trouble drilling holes in my polished concrete floors to install thresholds for the new wood floors. (Ripped out carpet). I got the fanciest one they had at Lowe’s for $8 and was told it would last and last and to use water when drilling. NOPE! I ordered a set of these as a back up. Opened the package and used one. Zip and zip. DONE. I couldn’t believe it. I finished the hole the other drill couldn’t do and did two others in just a few minutes. Just a regular DeWalt drill was all I needed. Don’t be fooled by the price. They are awesome. I am going to buy some more different sizes from this same company!

My husband runs a renovation business for the second decade.He probably knows everything about drill bits, or as they say, he could fill a book. )))He was using the set over the last couple of months.Considering the price benefit ratio, the bits' durability and performance are fairly good for occasional DIY projects.I doubt that professionals will show any interest in this product.
