Carbide Hole Saw Bit 3 3/8 Inch Concrete Hole Saw 86mm Carbide Hole Cutter Drill Stucco Brick Fiberglass Reinforced Plaster and Ceramic Tile Saw Through Drywall and Cement Block for Pipes and Conduit

Cuts through plaster like butter and would probably handle most softer materials nicely. It did not cut brick well at all. Spent 30 minutes with a hammer drill only to get about 1/4” into the brick.

3” bit went thru brick like a hot knife through butter! Still sharp!

If you plan on using this, the minimum bit that you can use is 1 1/2, the heard is kinda thick, anything smaller will make the head get stuck in the hole. Also, a small trick, put your bit in, tighten it, and then put a piece of tape around the screw so it doesnt come loose when you're drilling

I needed two holes in my stone for pipes. I drilled them before mounting b/c I was certain they'd crack and I'd have to start over. They did not, in fact. I diverted the water from my tiles saw so I could keep this wet as I cut and it went through quickly and precisely. Now, I have not done 100 of these so I don't know the long run durability, but for the two I did, it was great.

I needed to make 4 holes in my stucco-walled house. This hole saw kit lasted exactly 1 hole before it was completely worn out. If you only need to make 1 hole, this will do well for you. But after 1 it'll be completely useless. To drill the other 3 holes, I went to Ace and bought a $50 4" hole saw and it worked fine for the other 3 holes and still looks new.

Clean hole in my brick!

Won’t go through concrete, just wood
