Rated 1.0 out of 5.0 by Lance Does not cut Tile
This product is good for cutting backerboard, but not tile. I also purchased the RotoZip 1/4-in Diamond Grit Cutting Bit, and that worked fine on the tile.

Rated 1.0 out of 5.0 by FloridaBoy Cuts great. Breaks easily.
Exact same problem as a couple other reviewers. Was used to cut cement board for shower niche. Cut through very easily with almost no resistance. But after about 10 inches the bit snapped. Returned it for another. I cut just a little further than the last one but it did exactly the same thing. I was not forcing the tool, which was gliding through the cement board very easily. I've used the Rotozip and thinner bits for drywall with no problems. Very disappointed.

The zip bit was very handy with cutting out dry wall for electrical boxes. Made the task very simple and quick.

I went through three of these bits to create one hole for my shower head pipe. Maybe I was doing something wrong but there has to be an easier way. This was my first tile project too so there is always a large learning curve when you're doing your bathroom remodel yourself.

I needed to modify some cutouts in our kitchen when we upgraded our electrical panel. I bought this tip and it worked great for what it does. It made a 3 inch cut in about 30 seconds. It cut through thin tile extremely quickly. The only thing is it is VERY messy. It essentially renders the tile into dust, so it'll create fine dust around the area, and a lot of it. I highly recommend laying something down to collect it. Wear a mask as well.
I've used it for other purposes, and I've found a few tips that helped. I had a couple other cuts I needed to make, and I found out the tip of it wears out very quickly. DO NOT USE IT as a drill! Get a tile drill to make the first hole. The tip will get very hot and it'll basically melt down.
Also, watch out carefully for overheating. If it overheats (you'll notice it slow down), stop immediately and remove the bit and allow it to cool. It creates a LOT of friction, and overheating will destroy the bit. Allow it to cool and it'll last a lot longer. You can vary the point that's doing the drilling in and out as well, to cut along different parts of the bit to keep from damaging just one point on the bit.
Use these points and it'll last infinitely longer.

I bought this bit and a concrete bit to drill into tile I would still be drilling if it wasn't for this bit. The tile was so hard that nothing would penetrate it. finally I put this on my hammer drill and I started to make progress.

Bought this to do a quick cutout in incorrectly mounted Hardiebacker cement board. Snapped one seconds into the first use. These tools do great on drywall, but most definitely not on cement board.
