Diamond Hole Saw

I used this dry on 8mm porcelain tile on a drill press. Dusty so be careful. Minimal chipping, but always some on ends/edges. It’ll probably be necessary to burn a couple of tiles to get the measurements exactly right but it can be done. Making a cardboard template is useful too. Fits the name brand 4.5” shower valve seal perfectly after some small adjustment with a diamond block or file to clean up the edges after drilling. One more thing, clamp your work down so that when you are near the end of your hole and the bit grabs and spins your work it won’t hurt you or destroy the piece.

When I embarked on the harrowing journey of bathroom renovation, I thought the toughest challenge would be choosing between fifty shades of beige for the tiles. Little did I know, the real test of my DIY mettle would come when I needed to drill a hole through my newly acquired, stubborn-as-a-mule porcelain tiles. Enter the Luomorgo 35mm Diamond Hole Saw - the cape-wearing, laser-eyed superhero of drill bits. The moment it arrived, packaged like the crown jewels, I knew my prayers had been answered. Not only did it promise to glide through porcelain with the grace of a ballroom dancer, but it also boasted the ability to tackle glass, ceramic, and marble - essentially, the Avengers of surfaces. With my drill in hand and the Luomorgo bit attached, I felt like Thor wielding Mjolnir. Spoiler alert: the tile didn't stand a chance. Pros: - Mightier Than Thor's Hammer: This bit goes through tough surfaces like a hot knife through butter, or Thor's hammer through... well, anything. - No More Rusty Business: The nickel-plated surface means it’s more resistant to rusting than my resolve to finish this renovation. - Cuts Like a Dream: The cut was so smooth, my tiles probably didn't realize they'd been drilled until it was over. - Chip Evacuation: The side chip holes ensure waste removal is cleaner than my language when I finally saw the hole. - Wide-Ranging Powers: From glass to granite, this diamond hole saw is like the utility belt of Batman - prepared for any scenario. Cons: - Too Smooth?: The cuts were so effortless, I was momentarily deprived of my DIY war stories. - Addictive: I now wander my house, looking for things to drill holes in. The dog is getting worried. - Water Required: Needs water for cooling, slightly dampening my walk-off drilling fantasies in a cloud of practicality.

Excellent product for unbeatable price

I had to drill one hole in porcelain tile for a DIY shower remodel. I didn't want to spend $40-60 if I could use a cheaper saw that likely I'll not use again so I took a chance on this. It worked better than I'd hoped. I was a bit concerned that it didn't have a centering drill, but I was also concerned that the centering bit just added to the stress on the tile and a would be possible source of cracking. I drew a circle in a practice tile and carefully worked my way around the circle to get a starter groove and I kept the groove wet. It worked pretty well and I didn't risk damaging a tile I was going to use. Then I cut the tile to use. Already, the blade didn't seem as sharpe, but slowly and carefully i cut a nice hole. I'd recommend to a DIYer who only needs to cut a couple of holes, but not to a pro who needs to cut a lot of holes. It did work great for me.

These work well for my dremel tool.

This bit worked at cutting a hole in porcelain tile, I would highly recommend, it took a while and because the shaft was round, it slipped a few times, but just put some water on the tile and drill away.

Nice!

Absolutely terrible quality. I can’t even drill a single hole in the tile — and it’s not even porcelain, just regular ceramic tile — and the bit can’t make a single hole. It just melts.

Excelente producto, me permitió realizar la perforación fácilmente y mucho más rápido de lo que esperaba.

Not very durable, might go through a relatively soft ceramic tile, but anything thicker than 1/8", waste of time. The diamaonds just peel off and the cylinder overheats and bends.

Makes holes, no problem, just have to make sure to start properly. Maybe a bit at the angle to create some grove. After that is all smooth cutting. And price is great $4 a piece comparing to at least $14 in store

Corte suave, perforó en vidrio en un instante, no se nota desgaste en la pinta de la broca. A mí parecer, ideal para trabajos caseros y semi profesionales
