Review on High-Performance DEWALT Diamond Blade for Masonry, 7-Inch – DW4712B by Matthew Harris

There are so many blades to choose from and I only had to cut a piece of granite. I didn't want to pay a lot for a blade that I might never use again, but I was not disappointed when I used this blade. I was very surprised at how easy it cuts. I had a 70 inch piece of granite for a countertop that was just over an inch thick. I watched all the videos and had my guides on the spot. The blade cut granite in about a minute! I don't know how long this can go on because I may never need it again. If you are looking for a shatterproof blade then this is not for you. The chipping was minimal but if it's for the outside edge I don't think you would be happy with the results but if it's towards the wall. good to go I could also attribute small chips to the granite used. I don't know, but for general purposes it's great.
