5 Pcs 6mm Diamond Drill Bits, Porcelain Tile Drill Bit, Hex Shank Diamond Dry Drill Bits Sets for Granite, Ceramic, Marble, Tile Stone, Glass, Hard Materials

These worked well drilling through very hard bathroom tiles , 8 holes drilled with 1 bit used and a very good price , also bought a hole guide off Amazon who’ve made the whole process accurate and speedy

So I needed to drill holes into my outdoor porcelain tiles to hold up waterproof sockets. I looked at toolstation and for one diamond drill bit it was £15. Even with that people were reviewing the bit and saying they only got 2-3 holes from the bit before it needed to be retired. Yikes. So when I saw this on amazon, I thought - hey for £15, I get x5 bits. So if I only get 2/3 holes from one bit, then I get 5x the amount for the same price. So I decided to just go with these. The other reviews were not lying. If you do not cool down the bits with water and look after them - you only get 2 or 3 holes before they are cooked but that is FAR better than paying £15 for only one bit. So to me this was an absolute win. So how well do they work? They aren't lying when they say the head with skip around the tile. My advice? Get a sample tile and practice for a feel first. That's what I did. I discovered that you need to hold it at 45deg (like they recommend) but at FULL drill speed, and holding the drill tight against the direction of where it wants to go. Once you have a little bit of a dig, re-align it into the hole and press hard and full speed while wiggling it slightly. Each hold took roughly 2/3 minutes to get through a 20mm tile which isn't too bad! So overall, don't expect these bits to last - 2/3 holes tops for each but compared to going to toolstation and buying just one? These are a far better deal. I've posted some pictures so you can see what I'm talking about.

Great for drilling through tiles.

They drill through ceramic quickly and accurately. Can also be used to quickly shape or widen holes, like a file

If you only need a few holes drilled through the porcelain tiles these are excellent value and deliver. Not overheating them gives you a bit more life but these are excellent value compared to more "professional" alternatives. Have a practice to get the hang of how to start the hole but once you get the "bite" and the hole started it was straight forward to drill though. Would definitley recommend for the DIY infrequent requirement. So when I saw this on amazon, I thought - hey for £15, I get x5 bits.

Brilliant. Half the price of local trade store and I get 5 bits which will do 3/4 holes each. I was drilling 9.5mm porcelain. Kept stopping every 10 secs and running in bucket of water. Easy enough. I put duct tape along where I’m cutting just to give the tile that little bit more strength from cracking. Also no hammer mode on drill! Happy to report no cracked tiles. Brilliant value.

These work well but be warned - each drillbit will only last max 3x uses with 15mm thick porcelain tiles before going blunt ( you can tell theyre blunt when they stop grinding. Make sure you have enough.

the drill bits arrived earlier than predicted. They worked well drill my tough Porcelain tiles. I would recommend them.
