SHDIATOOL Dry Diamond Drill Core Bit Diameter 20mm Vacuum Brazed Drilling Porcelain Tile Granite Marble

I used one to drill porcelain tiles in my bathroom, 13 holes to drill, it did it with ease, and definitely could do more, some drills are blunt after 3 holes, very happy!

Used for porcelain and ceramic tiles as well as brick. Don’t last forever but cut neat holes with minimal effort

Great for a few holes per bit if grinding into porcelain tiles

Needed to cut a hole through porcelain floor tile for radiator pipes.This did the job better than expected.Cut through in 10 - 20 seconds.I directed garden water hose pipe to cutting area which worked well.Second attempt I angled the bit not horizontally which left it oval shaped but used another tile and got it perfect.Minimal chips and I'm sure if I took my time or watch a how to video I could have done a better job.X3 drills and all worked great and no signs of wear/ damage to drill bit.

I've used diamond core drills in the past to do 8mm holes using a drill and each hole took ages to drill. Using this bit in an angle grinder was like a hot knife through butter by comparison. I had a large thick porcelain tile I needed to break out (see photos) the advice was rake out grout and then drill holes to make it easier to smash tile.Only challenge was starting the holes due to the bit tending to run around on the tile. So I used a piece of wood with a V notch taken out to rest the bit in. That did the job! Precision and speed/ I would use one of this bits the next time I need to make holes in a tile and abandon my previous bits.

Honestly 100% Recommend. I tried so many drill bits to drill into tiles and every time they cracked or took me ages to get through.Using these in my angle grinder was so easy and such a nice cut. I would spend more and get these in every size.The only down side is they don’t last very long as the diamond tops wear (as any would).Great quality and deserved a review!

I was scepitcal at first as I have used cheap diamond bits without much success. I even tried a branded Makita 10mm bit which barely cut 3 holes in porcelain tiles before completely wearing down and becoming useless.Thought I would give these a go and after 3 holes, the first bit doesnt look likes its ground down at all... not even opened the second bit yet.Note there is a M14 shank which fits in a grinder. The speed of the grinder is no problem for the bit and it cuts porcelain within seconds. You still have the skidding problem, I made a V with timber to help hold the bit to get started and no problem.Suitably impressed for the money.

I've purchased these 3 times now.They start really well, but soon taper off.Fund them as an alternative to rubi, which I find do the same.When I started using the grinder type diamond drills I thought I'd found the holy grail, but as time has gone on I've realised that per hole, the novelty is an expensive one.I've settled on, for now, a return to the drill type, and have found a set which I find great value for money.But I can't tell you .......... as the price will go up!Soz

Très bien
