"This cutter worked fine for me on ceramic wall tiles, cut a nice neat hole. I used it 4 times and it doesn't look worn out. Don't forget to order the arbour as well, I didn't and found I had to make a second visit to the store."
"I have used this product probably a dozen times on various ceramic tiles, it cuts a neat hole, is easy to use as long as you don't us a hammer action. For the price it is a good buy once you have the arbor. My cutter has no signs of wear as yet. I can't comment on how it would cope with a harder tile or metal but for ceramic tiles its great."
"I bought this holesaw for drilling metal enclosures to fit stuffing glands...result?....Its rubbish! The holesaw suggests to drill slow but i would've have spent all day drilling that enclosure. I suggest you buy the cheaper holesaw with the teeth which chewed through the enclosure like a bulldog on a squeaky toy. Ive used the Grit edged holesaw on 1 tile and a few plastic patrices and already its looking warn.
