Glass Cutting Disc 4-1/2 Inch (5PCS) for Angle Grinder with 7/8" Arbor Hole, 0.63" Ultra-Thin Saw Blade Wheel Polishing Diamond Cutting Disc for Glass, Jade, Wine Bottles, Tile, Ceramic, Marble

Smooth cutting

Nothing bad to say great quality

I used it to cut some stained glass. It cuts very fast but is somewhat difficult to make very accurate cuts. Overall it did what I needed it to do.

My only concern is the chipping it can cause. I did read other reviews that said the same thing. I need to try some different techniques to stop the chipping. Maybe fill the bottle with sand? They do cut the glass very easy.

Really good for cutting

Good disc

Very good product, Cut perfect glass tile

Can’t cut glass as advertised. I placed the glass on top of the rug, water was applied to the glass as a small jet stream, run the saw blade across is slowly… it seemed like a success at first; however, to find out that in a fraction of a second the entire glass piece was shattered to smaller pieces. I’ll keep it to cut granite and tile instead… because the material resonance frequency is higher than that of quenched tempered glass. This cutting material can be improved to actually cut glass if the designer can lower the resonance frequencies of the alloyed used.

I cut 3/4 inch plate glass with my portable saw and water from a 3/16 in dia hose tie wrapped to saw to direct water into the cut. I cut the glass at rate of about an inch in 6 seconds. I cut about 15 feet of glass before I felt the blade was slowing down. I was quite happy with the performance of the blades.

Coupe très bien la vitre

Lo compre para cortar botellas de cristal y es excelente, la corta como si fuera mantequilla, solo tardas unos segundos en cortar una botella redonda y el acabado es excelente, solo necesitas lijar los bordes con una lija fina y listo.

Fait le travail très bien, verre et pâte de verre , quart

OK
