RotoZip TC-1 Tilecut Bit
I've been using my Rotozip for 2 or 3 years now, and the carbide bits are the only thing to use for certain jobs.

Don't even think of cutting 1/2" backer board with this.
I am in the process of laying about 250 sf of tile and purchased these bits to allow me to make cuts in 1/2" backerboard (cement board). After one painfiully slow cut, the bit broke. I contacted Rotozip and they recommended using the RZ250 (1/4" shank bit). It's working out very well! RotoZip says that this bit should also work, but I think not. If you are cutting thicker cement board, pay the extra [money] and get the RZ250 bit.

Not good for floor tile
I thought this tool was the perfect solution for my tiling project. Heed the warnings about not using it on floor tile or thick ceramic tile. I burned up a blade trying to drill through floor tile. It worked to make an irregular cut in the floor tile before it was installed but it took FOREVER. It was actually quicker for me to drive to the hardware store and have them cut the tile.

It did work great on the cement backer board. I just noticed the diamond wheel for cutting tile and I am hoping that will be better.

roto tile bits
roto tile bits will do a good job on thin ceramic tiles for cutouts-straight cuts are hard-thick tile,marble,etc-forget it--bits burn up quickly on cement backer board and at $5.99 are not cost effective. Buy a small diamond blade for your 4" grinder--makita-dewalt etc. which are very effective, with a little practice they work fine--wear a dust mask and eye protection

Not good on large floor tile
I read several good reviews on this product, but they all seem to relate to wall tile. I found that the bit performs poorly on large floor tile. ...
