Review on 🧱 High-Quality Muzerdo Concrete Shank Cement Bricks for Enhanced Durability by Justin Olson

Good concrete hole saws are very expensive. A large branded saw can cost twice as much as this entire set so I wasn't sure what to expect. Good first. They come in a nice foam case that protects the carbides and makes them easy to store and transport. The saws are made from heavy gauge steel that should easily withstand the abrasive conditions of concrete. In this respect they are similar to expensive saws. The carbides are sharp and well brazed to the saw bodies. During my testing, I didn't have a single loose or chipped tooth. And bad. These saws are slow. All concrete hole saws are slow, but these are slower than usual. Mounted in my SDS, set to a rotating hammer, I only punched about 3/8 inch in hard concrete and about 1 inch in soft brick in 10 minutes. The teeth are sharp and at the right angle so I don't know why they are so slow. I wouldn't want to breach the concrete foundation. That takes a whole day. The saws thread onto the mandrel but there is no thrust ring so the threads are wedged tight by the impact action of drilling. To loosen them you need to remove the pilot attachment, insert a 3/8 inch rod into the holes in the saw and tap on it. A little tricky with the equipment. To take out the pilot jet, all you have to do is remove the hex screw with a 1/2 socket wrench. It's easy when the saw isn't in place, but when the saw is stuck on the shaft it's almost impossible to hit the bolt head with a wrench. I need to replace it with a socket head cap screw. In the end, these saws were a little disappointing. They certainly work, but I have no plans to use them for anything harder than brick. If you value your time, the more expensive parts suddenly look a lot more attractive.
