Had to drill a 4.5" dryer vent through 8"concrete reinforced block.Took roughly 15mintues of drilling with weak dril.Light pressure letting the tool do the work.Water hose supplying constant water to the bit.Used a shallow 4.5" hole saw with pilot but to start, this prevented walk.

Complete junk. Teeth broke off 3 inches into the core of relatively soft concrete. Maybe I received a defective bit but nothing looks defective in the drill bit itself.

Went through brick and cinder wall without issues, I had a nice sdr hammer drill which makes life easier also. Hoping it can make it through some concrete curb this summer. Worth the money for what I needed

We used an insect sprayer with just water to spray on the saw to keep it cool, it took 15 minutes with a couple of short breaks. Saw is worth its weight in gold.

Worked great and easily went through 8 inches of cinder block and concrete in a matter of minutes with electric power hand drill. Photos show hole (larger hole on top in photo) and the tool after use.

Used to cut through the length of a brick. That was the orientation of my wall. Getting started was tricky since there is no pilot bit. I started on an edge until a semicircle was formed then lined up for the full cut. A tooth was broken off during the cut, but it kept going. I didnt know until the cut was done. Overall worked well. Glad I purchased it.

I was skeptical about using a core bit from Amazon, but at the price i figured i have to give it a try.I was drilling in a shotcrete pool wall (much stronger than your average concrete block/slab) this bit had no issues drilling through 8” wall and the dust was being removed at a fantastic rate.Fast, good quality drill which definitely is worth the price! I am not sure about durability, as I only needed to drill one hole, but it still looks pretty much new so definitely good value for your money!
