I was definitely hesitant at first, but wow! This thing did its job on hardie backer and porcelain tile!I thought for sure my angle grinder would run away and cause so much damage to the tile, but as long as you start at an angle like the directions say, it cut through like butter. I only used it on one piece of hardie backer and one piece of tile so far, so I’m not sure how long it’ll last, but it still looks like it has plenty of life in it. I’d highly recommend this hole saw bit!

This works very well. I don't know how long it will last, but it did not seem to lose any of the grit the few times I've used it to date. It is a good bit.

This whole cutter worked well. It fit three different 90° grinder arbors, porter cable, harbor freight, Makita. Does what it is supposed to do.
