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

Had previously bought a diamond tipped drill from B&Q for £7/8, just about drilled two holes taking 10 minutes, then good for nothing, one of thesemade light work of drilling 3 holes, probably only good for one or two more, follow the instructions and they work brilliantly, people have said they slip when on the 45o I used masking tape to start into , no issues at all. Bargain!

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 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.

Good price fur good product

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.

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

Bought to cut four 6mm holes in new porcelain 9mm tiles. Require careful starting at 45 degree angle to avoid run off and marking but once started the hole is neat and true to size. Four holes and two worn out bits later I was pleased with the result. Used a standard 18v battery powered drill on slow speed without lubricant. May last longer with lubricant but did not want to risk staining the grouting. Risk of tile breaking must be close to zero if away from edge. I hade to drill 5mm from tile edge without breakage but was very careful. More like grinding than drilling.

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.
