6-Inch Diamond Coated Flat File, Medium #150 Grit, for Glass, Tile, Ceramic and Stone, Granite, Marble, Concrete, Big Comfort Massage Handle Grip, Total Length 10.4-Inches, Glass Ceramic Tile File

The handle is comfortable and for me the diamond grit stayed in place and I prefer a flat file like this with bare edges.

I used this file to smooth out some broken edges of a ceramic mug and it worked fine.

Really happy with this file, have used it a while now and still works how it should be.

Needed to shave between 2 tiles attached to the wall. This was the thickness I needed to get in between them. So for that purpose very good. Reason for 3 stars is the coating on them was blistered on one side and cracked. Easier to keep them than return but quality control is poor. Handle is comfortable but not great quality I’m afraid

Used on some quarts and it worked perfectly

Filed down mosaic glass tiles very well. So far so very good. Early days but no sign of wear on the file yet.Good size & comfortable.

Fantastic, made filing imperfections off my concrete ornamental castings a breeze.Very pleased with purchase!

Good ceramic file for bone etc. Useful for luthiers/craftspeople etc

Very good file. Works fine.

I use the 150 grit diamond file the most for shaping knife blades. Unlike many on Amazon, this one is not too small. Haven't used it enough to see how long it'll last, but so far I'm happy with its performance.

Fonctionne bien, mais ne vous attendez pas à des résultats rapides. Cela demande de la patience.

Qualità prezzo eccellente

La compré para pulir piedras duras y va genial. H probado con metal duro de teusteno y también funciona..llevo 1 día solo con ella. Queda por probar la durabilidad. De momento un 10
