Review on 💎 Diamond Exchange Blade 2055005: Enhance Cutting Precision with a 4 Inch Design by Ethan Delaney

Bought a 1 inch diamond hole saw from a store. The fourth hole required me to push hard to even get it to cut and it took over five minutes with a small drill. For the second part of my project I needed a 1 1/4 inch hole saw so I decided to give Revain a try. This hole saw is just under half the price of my local national store. The quality of this hole saw is amazing. I cut a dozen holes in 3/4" granite, in under 60 seconds each, much faster than a commercial saw, and it shows no signs of slowing down or wearing out. I actually used the outside edge to shape the granite freehand pieces, abuse I didn't think it would survive. (I machined the back of the holes) I will never buy a hole saw from a store again.
