Review on SHDIATOOL Diamond Coating for Concrete, Marble, and Granite Surfaces by Jose Strong

I used this tool with a 12" extension and 5/8-11 hex shank to cut through 16" bricks and it worked like a spell. I cut like butter. It has an abrasive on the side to make a hole just a hair's breadth larger than the entire saw. Makes inserting and removing the saw a breeze. Didn't dull and was a heavy cutter throughout the process. Still in great shape. I was able to slip a 1-1/2 PVC pipe into the hole left by this saw so I could run some wires through the wall. Worked like a champ and is not a throw away tool, it has held up well.
