"Tried various drill bits for porcelain tiles and none of them worked, this is by far the best drill bit on the market for these tiles. Screwfix also is the cheapest place to buy these from. Don't hesitate to buy this, other drill bits are not a patch on this one. We had to spend quite a bit of money on drill bits before we found this one."
"This bit stopped me from killing myself , I burnt out bit after bit on my porcelain tiles , it still takes a couple of minutes to drill through but its well worth it , I would recommend this to anyone drilling porcelain tiles , don't waste your money other bits like I did ."
"Thank goodness for this drill bit. Having bought what turned out to be the hardest porcelain tiles on the planet we were dreading drilling the bathroom fixtures into position. A chance comment lead me to this brand. I had looked in the catalogue but had not found them at screwfix but it popped up in a screwfix internet search. Expensive but no damaged tiles and a great product. worth the extra money. (ps Anyone want to buy all the other diamond drill bits I bought before finding this one?)"
"Best drill bit I've used. I was drilling porcalin tiles the hardest ones I've drilled. I recommend starting the hole with a bosch multipurpose drill bit Nd then using this . I've drilled around 16 holes with this and it's still going strong ."
"Expensive, but impressive - the answer to drilling through fixed porcelain tiles. It went through 10mm tiles in seconds with no obvious sign of wear (only 4 holes so far, but looks good for many more)"
"I have purchased several diamond " tipped drills to try and drill porcelain tiles, they have ranged between £5 & £11. I have also spent hours trying to drill through these tiles and am working at a current rate of 2 dill bits per hole per hour. on Saturday I finally gave up and just bought the most expensive bit I could fond that was supposed to do the Job. IT WORKED. I have drilled 8 hole so far and that is inside 1/2 an hour. this does what it says on the tin, when I was beginning to doubt anything other drill bits claimed............................thank goodness."
"Unbelievable. 11mm thick grade 5 porcelain tiles. Hole 16 drilled as good as hole1. Tip is still gritty and sparkly, like new. Everyone dreads last day on a bathroom job when the customer brings a box full of accessories to fit. No problem with this amazing piece of kit. Nothing else I've tried (10 years) comes close."
"Not the cheapest bit but I've done 25 holes so far in very hard porcelain tiles with no cracks. Its starting to show signs of wear but with patience is still cutting holes. I borrowed another bit off my plumber and burn't it out in one hole and continue to use this bit. I'd certainly get another if I were fitting another bathroom out."
"I've only used the drill bit on one job (10 holes) which was 10mm ceramic tiles. The drill bit went through very quick and clean however not very easy to start the drilling as the bit wouldn't stop wandering. I found myself using an old ceramic bit which still starts the holes effortlessly to mark all holes, then swapped to the Marcrist."
"Tried various other drill bits but lucky to get half way through. Although expensive it does get through 12mm porcelain tiles. I drilled 16 holes not sure if it will do many more. You also need a good drill"
"Having spent 3 hours and blunted 2 tile drill bits drilling 4 holes in our porcelain tiles, I searched the Internet for a better option. The drill bit is a bit expensive but i think worth it, I drilled 4 holes with ease and in a fraction of the time. I used a drill guide to start the hole and then drilled at a steady speed with no fuss. It's self cooling so no messing with water spraying. If like me you struggled to drill through porcelain tiles then I'd suggest giving this drill bit of a go."
