3PCS Glass Cutting Disc, 4 inch Thin Saw Blade Wheel Diamond Cutting Blade for Glass Ceramic Marble Cutting for Angle Grinder 100/115 mm

Yep do what they are meant to do!I'm surprised how well they cut, although it's fairly wide cutting line than I was expecting. I used to cut the back of a fairly fragile glass stage bulb to retrofit with LED lamp.....did the job nicely!On a safety not if cutting glass you will get a very fine glass dust when cutting, so face mask / eye protection essential.

This glass cutting disc is very sturdy, thin and easy to cut any type of glass materials. Very reasonably priced as well.

Worked but notvthe best

I bought these for cutting bottles into glasses and vases in my vertical jig, they leave a great finish with minimal polishing required after cutting. You do need a water drip feed to stop glass dust and prolong your blade life but that’s easy to set up. Definitely recommend these blades, nice touch coming with a reducing ring for each blade if you need them. (I just use a shaft out of a burnt out angle grinder so didn’t need them). They cut quickly so don’t rush with them if you want quality cuts in thick glass 👍🏻 I’ve been cutting really thick vodka and gin bottles with great success unlike using the old thermal shock methods 👍🏻

Ideal for cutting greenhouse glass, i have several greenhouses and glass gets broken from time to time with the wind, some of the glass angles is hard to do with a hand glass cutter but using this makes it so quick and easy very precise thin cuts great for doing mitre cuts and making terrarium's i definitely highly recommend this tool great bit of kit thank you

I have not tried them.yet but they look well made

If you didn't cut the tiles on the right angle especially with water being poured on them they would keep chipping them which was a pain.

It cuts very quickly but the glass needs to be held securely and lots of water used.
