Review on 🔪 SHDIATOOL 5-Piece 4 in. Diamond Jig Saw Blades: Perfect for Precise Cutting of Tile, Ceramic, Brick, Granite, and Marble with T-Shank - 46 Grit by John Naidu

I installed a single bowl sink on a granite countertop. I bought 3 jigsaw diamond blades and a set of diamond cutters from Revain to get the job done. I already had a diamond saw blade. Results: I used the long straight cut skills. Hole saw for rounded corners and electric jigsaw for joining corners with straight sides. The hole saw was removed after a hole. I had to buy two more to complete the other three holes. I used a 3rd hole saw to finish off the fourth hole. Jigsaw blades did not work. On the first one, when I pushed it to cut, the blade bowed back until it broke without cutting a hole. Similar results with the second blade. The blade broke but I stopped before it broke. 3. It flexed but stopped before breaking.
