Used with a hand-grinder, it worked well widening some holes in 3/8 inch porcelain tile.

One of the most useful tools Ive ever bought. It would have been impossible to shape curves and complicated patterns on ceramic tiles without this bit.

AWESOME! Exactly what I needed to enlarge a hole in my tile wall.

Amazing tool. I had to widen a hole in a porcelain sink and this little baby made short work of it. Not only did it work fast and almost effortlessly it also left a very smooth finish to the porcelain. Excellent investment. I would reccomend this bit to anyone.

I used this for smoothing out edges on granite countertops on a 4 inch angle grinder. I also was able to bevel the edges to match the factory edge, Use long smooth strokes with very light pressure. After that I used diamond polishing pads to shine it up.

Used this diamond milling bit to grind through a bathroom granite countertop and expand the sink drain hole so I could install a new drainpipe with pop up drain. It worked like a charm and was actually fun to use with a Makita angle grinder.

An absolute life saver. I had a granite sink that the faucet hole was underside and I had no idea what to do. Then I found this tool and less then a minute later it was done. No chips, scratches or bumps.

I had a limestone vanity sink top that had holes that were too small to fit standard hardware. Using this tool (10mm size) I enlarged a 1" diameter hole to 1 1/2" with ease!

Used this diamond milling bit on a ceramic project. The milling bit was easy to use. It was used to correct a problem on a 120 year old ceramic butter churn.

Got this bit to cut a large hole in ceramic tile. It takes a while to use but works well. Dont force the bit, take your time.
William P.
Used this tool to shape hole cuts in tiles where my hole saw wasnt large enough. Wish I had found it long ago.

It got the job done in a matter of seconds allowing menti use the faucet I had recently purchased but didnt fit the size holes in my countertop

Worked perfect! Used to enlarge an existing hole in a brick and mortar wall. Have been looking for a diamond-coated rotary rasp for some time, this is essentially that.

This product save me quite a bit of money, reaming out holes in the marble countertop when larger fixtures replaced the old ones.
Krissy S.
Fantastic tool to enlarge the sink hole for our new faucet. I do recommend.

Replace Bathroom faucets -realized the new box stores faucets require a larger hole to drop handle through.
Burrow out each hole in ceramic sink (2 to 3 min) drop new handles in cleanup done.

I needed to make a 4 1/2 inch hole (didnt have to be a perfect circle as its covered) I had a 2 inch tile hole saw bit so drilled hole the opened hole to 4 1/2. Worked great.
