Rated 4.0 out of 5.0 by BobO Enlarge a hole in your granite counter
I needed to widen the faucet hole in our Uba Tuba granite counter top to accommodate a single style faucet. The Faucet required a 1 3/16" hole but the counter was pre-drilled to an inch for our old three hole style faucet.
Since I don't own a rotozip tool I used a regular corded drill and just eyeballed the entire operation until the hole was large enough. All I did was use the drill on its highest speed and repeatedly move the bit in circles around the inside of the hole, trying to keep it as plumb as possible throughout the entire operation (took me about 20-30 minutes). Make sure you stop every once and a while to avoid overheating the bit. I used a dry bit.
Dust will fly, so if you've got another set of hands have them hold the vacuum near the location to minimize the particles.
Overall it worked great and I have no complaints. I'm glad to save money doing it myself and there was little risk of damaging the granite top since there was really no impact, just more of a sanding of the inner hole. Oh yeah, do not WIPE the dust around on your counter!! Use a vacuum to suck up whatever lands so that you don't etch the shiny finished top!! (yeah I made this mistake near the hole, luckily its covered by the base plate)

Rated 5.0 out of 5.0 by CSC Porcelain Tile Cut Fine
Received the bit for a present. Doing a bathroom remodel using 12x12 porcelain tile.
If you have a little patience, this bit will do the job with NO problem (I used my Rotozip freehand). Final cut is not as 'clean', but will be hidden by toilet and pipe covers anyways. Once you get through the tile, go clockwise in an up-and-down motion with a little sideways pressure. I practiced on some porcelain tiles from the Habitat store.
Tip: if you're cutting a semi-circle (see photo), start from the tile edge first, and come through about 1 or 2 inches on both sides, then slowly come through to the middle (by doing it this way, the tile edge will not break off).
Saved me a ton of money (vs. buying or renting a wet-tile saw). I did not waste one single tile.

Would not plunge cut into a floor tile, however it did a decent job on wall tile.

Rated 5.0 out of 5.0 by albow I took a chance
I've never tried these diamond bits before, so I bought the one with the most diamond on it so it would have the best chance to impress me, or fall flat. I'm impressed! I Once you get through the glazed surface on the quarter-inch floor tile, it eats a line or needed curve with no problem. On the thinner bathroom tile it was a breeze. I used it plenty, yet it still has some life left. I used an ordinary DeWalt cordless drill on high speed. I will never do any more tile work without this tool.

Rated 5.0 out of 5.0 by iwood I used this today to cut holes in glass tile, NO PROB! (need the 5/16 diamond hole saw to start)
The tile is glass, common now. The tile man cut holes too big for today's demanding fixtures. I used a Home Depot sold Rigid 5/16 diamond hole saw to start the hole, and enlarged, with LOTS of water, to 1 1/18", with a Roto Zip bit like this, NO PROBLEM. ( Took 1 try on scrap, and 20 minuets per hole). Now the tile will be replaced, and allow for a shower fixture with demanding dimensions. I can no longer find these in the HD stores, mabee stolen too often. Buy them online!

Rated 1.0 out of 5.0 by MrTile This bit DOES NOT cut porcelain tiles!!!
This bit will not cut porcelain tiles. However, it will shred thru ceramic tiles like butter. I found that the 1/8 AND the 5/32 tile bits for the RotoZip work great for cutting thru ceramic tiles and is less then a third of the cost.
Porcelain tiles are really dense and a little more fragile then ceramic. This drill bit (at any variable speed) just didn't work... Buy a wet saw.

Rated 5.0 out of 5.0 by John This product exceeded my expectation.
I used this bit while putting floor tile in my bath room. Did circle and curve cuts without a problem. I'm a first time user and this bit did the job much better than I expected.
The sales person was very courteous and helpful in placing the order. The product was received right on time.

This proved great for cutting those non round holes in 3/8 marble tile. Fast cutting (dry). A must have for the do it yourself tile installer.
