Review on CO Z 12 Inch Scaling Masonry Concrete by Michael Rosario

Update: March 2021 Shipping was fast. They fit my Dewalt SDS Max (DCH614x2) drill perfectly. The shaft may need some lubrication the first time you use it. This is of course up to you. Some people believe in shaft lubrication and others don't. they are heavy And then I was fooled. After 5 minutes on the concrete, these things started folding like tacos. I have not used a wide chisel before. I will be saving this solely for tile chipping and thin cutting. I think it should be able to handle that without much wear and tear. But the fence posts are concrete, not so much. They'll get the job done if you just try to break a specific post or two, but after that it's probably scams and time to buy more. Unfortunately I have 4 left. I will use them until they almost disappear and wear out. You can take a grinder and try reshaping the ends. I'll buy a brand name chisel like Bosch or Dewalt and see if they get the same results. If so, I'll write a third review and give them a lot more leeway than I expected.
