View Full Version : Is there a dremel attachment for cutting travertine?

I need to cut into the middle of a travertine tile to make a hole for the toilet in my bathroom. I have a Dremel tool, and was wondering if there was an attachment for that purpose? I've seen one for the rotozip that looks like a drill. However all I can find for the Dremel is a small circular blade attachment, nothing I can plunge into the tile with.

Is there anything out there I can use, I don't have an angle grinder, just my wetsaw and dremel.

I haven't had much success with the Dremel on anything but soft white bodied ceramics. You could plunge cut it to death and nip it out.

Plunge cut the hole with the Wetsaw and nip out any little bits you can't quite cut out clean. Save the Dremel for cleaning out excess thinset from the grout joints. The tile cutting bit for the Dremel is good for that.

If you have a large amount of time on your hands you could buy some diamond cutting wheels for your dremel from this eBay seller (http://stores.ebay.com/THK-Diamond-Tools). Type "cutting wheel" into the store search box to find them. I cut the two squares in the travertine below using the dremel to finish off the cuts I started with my wet saw. Very time consuming, but it can be done. I think I'd actually draw an octagon on the tile and if you have an overhead blade type of wet saw make plunge cuts along the straight lines and finish with the dremel. Or you could "cheat' and cut the tile in half and make a series of kerf cuts and break out the stone.

being this is for a toilet cut out and it doesn't have to be perfect, I would cut the back of the stone with plunge cuts on the wetsaw in an octagon pattern just breaking through to the front, tap it out and nip to make fit with nippers.

Eva,

I can't speak to Travertine, but I just finished my tub surround using glazed porcelain, and I used a 1/8" Rotozip carbide bit in my Dremel and it worked like gangbusters. I punched the tub pipe hole and shower pipie hole. I expect I could have done the shower regulator too, but it fell on a grout line so I used the Felker. I am at work, so my stuff isn't accesible, but I will take a few pitchers, and get you the Rotozip part # tonight if you can wait. :)

You can use Rotozip parts for the Dremel? Excellent! :yipee: I'd probably try that first, it would seem to be the cleanest solution, if it works=)

Eva,

Here is what I used:

Rotozip Spiracut bit Part Number: RX125, 1/8" diameter. It was pretty tight in the collet but it fit.

On the package it says solid carbide, curved and angular cuts, cultered marble, plaster.

At the Bottom it says Wall Tile & Cement Board, and in small print Not for Floor Tile.

That being said, I used one bit to punch the hole for my tub line and my shower riser...and I did use it for a small cut on a floor tile ;) I also used it to clear a bunch of mortar out of some of the joints in my niche. One bit lasted about 3 linear feet of cutting through porcelain and mortar.

It does take a little practice to keep good lines as it wants to pull to the side it rotates into. I know you can also get a collar just like the one that comes with a Rotozip, but I didn't use one.

Hope this helps in some way.

I've used dremel bits for my rotozip so I'm sure the dremel can use rotozip bits.

when using the rotozip bits to cut tile, they will work but TAKE IT SLOWLY. The little bits can over heat very quickly and snap. At an average of 10 bucks each, the carbide bits can get more expensive than buying a diamond wheel for the angle grinder if you do a lot of large holes like a toilet flange.

I usually save the Rotozip for small holes for supply lines and shower heads.

The Rotozip is a bigger and more powerful tool than the Dremel. You may be able to interchange bits; but you won't bring the torque and HP.
