🔪 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 Review

I bought these to help cut a round chimney hole in stacked iron oxide. Did a pathetic job. I ended up buying a diamond coated Drexel wheel along with small diamond studded drums for final smoothing.

These blades didn't last very long. I'm a very good tiler and in my opinion they are terrible. The blade shank did not fit completely into the saw. This happened on 4 out of 6 blades, resulting in premature failure. Wouldn't recommend it.

I bought a set of five with the intention of using them all for a job cutting fiberglass and epoxy tubing. This material is difficult for carbide tools, and with a 20-foot cut, I realized diamond was the way to go. These blades are thicker than I would like but they hold up well and to my surprise it only took one blade to finish the job. All of my cuts were straight, but I noticed there was enough sand on the sides of the blade to accommodate the curves.

Depending on your plans, this could be for you. I was trying to cut a hole in an old marble shell countertop for a sink. They broke too easily. I was on my third before doing a foot length. It was at this point that I realized the sink was too thick for my work to be realistic. They cut marble and are good at working with thin materials; However, they come in a 3-pack for a reason. I would plan to stock up and schedule some slow, messy puzzle work on the road.

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…
