Uxcell Diamond Coated Marble Glass Hole Saw Cutter with 50mm Diameter and 51mm Long

I drilled holes for sink, bath, shower and toilet plumbing. 6 holes in all. All in a thick large format tile with a variegated surface. A few handy tips: Use a little water or it will get very hot and could break your tiles. I just poured a little water from a pitcher periodically. Also keep in mind that you'll have to have a steady hand if you're using a drill like I did (instead of a drill press). I stood with the tile on the ground between my feet and used my legs to keep the drill from skipping around when I started a hole. Holding the drill a little bit off of level helped too. I was able to get a shallow rut on one side and then flatten out to drill evenly.

Used this with a drill press and squirt bottle for lubricant. Went through about 20 glass bricks and did not notice any dulling on the last brick. Cut through a brick (3/8") in about 30 seconds to 1:00. Does seem cheaply made, so professional use it may not hold up.

Rips through abalone shell!

Worked great and good price

"Pacchetto contenuto : 2 x vetro foro sega." Non so bene cosa significhi ma a me sembra che ne dovevano essere 2. Comunque un prodotto abbastanza valido per hobbistica. Io l'ho preso per fare 6 fori su soglie di travertino e si è comportato abbastanza bene e forse si riesce a farne qualche altro non è ancora ridotto malissimo il precedente che avevo acquistato di altro fornitore è durato tre buchi. Quindi darei 5 stelle per il rapporto qualità prezzo ma ne metto solo tre per la definizione del "contenuto pacchetto".
