This item is worth every penny! I watched a video on YouTube that showed how to drill a few holes in a circle in a brick and then gouge the brick. Drilling the pilot hole took forever, I didn't want to drill another 8-10! Instead, I decided to look for a 4 inch masonry hole saw. Found. This hole saw cut through one of the toughest 60 year old bricks I have ever seen in less than 20 minutes. Use a 1/2" cord drill and let the saw do all the work. I would stop about every 30 seconds and drop it in the water. Best damn $50 I've ever spent on a project. If you're going through brick need to drill, this is for you.
