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.

These tile drill are pretty good. You get around 20 holes from them in porcelain. They match tile drills I’ve spend £50 per drill bit. Fantastic and well worth the money.

I needed to drill some holes in porcelain tiles and quickly realised my existing tile drills for ceramic tiles were not up to the job. These drills do work efficiently although the technique to start the drilling does take a bit of practice. So far I have drilled 11 holes using 2 of the drills and there is still some life left in the two drills. Cooling the drills in water at regular intervals is important to prolong the life of the drill bits. Given that they were significantly cheaper then other suitable drills, I am very pleased with them.

I don’t usually leave feedback. Ordered these for bathroom DIY job, to drill through 10mm Italian porcelain tile. They are fantastic. I drilled two holes per bit, could do more I am sure but they came as a pack of 5 and only 9 holes needed. I used a cheap suction drill bit guide to start and frequently added a little water to hole/bit. Used the little plastic tube they come in. Cut through the tile readily. I read complaints of slow and difficult but that’s what one would expect, it is not cutting like a sharp drill through would but abrading the very hard porcelain - imagine filing a hard rock. 10mins a hole max with repeated wetting reckon there’s plenty of life left in them.

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

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.

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.
