Superior Quality Diamond Masonry Tools by Steel Dragon Tools Review

Ryobi used this hole saw with a hammer drill to cut a hole in the board to leave the base. I don't like hammering/hitting concrete because it can loosen it with cracks. It was perfect for my cast, the Pancake Gang.

Great tool at a great price. I don't understand why all three pieces were bought from the same company and sent in three different packages. And they came 3 days in a row one after the other. Should have been sent as a unit but great tool and did the job

This drills the perfect hole in 4 inch thick brick in under two minutes. Keep the blade cool. As you can see from the photos, the tool does not wear out. I needed it to install an external radon fan. fasten well, and this hole saw will cut the hole with machine precision for a tight fit.
