RUBIDry Drilling in Ceramic, Porcelain, Natural Stone and Other Material | Operating Speed 14,000 r.p.m | DRYGRES DRILL BIT Ø3/4" (20 MM.)

Rubi product good as always. Thanks

Brilliant way of drilling tiles I used to use the wax 6mm core bits and I was lucky to get one bathroom out of one bit and there where £18 each . now I found these bits and there are more cost affective, double or triple the speed so can get as many holes done as I like in no time at all , I’m on my third porcelain tiled bathroom and the bit is still so sharp well worth it . A lot of people I no are put of with using a grinder and not a drill , don’t be !! give it a go practice first and you won’t look backThanks grant

Took a gamble on this based on the positive reviews across sites and they proved to be accurate.Excellent value for money in the end and went allot further than I expected. This 12mm bit managed 56 holes through 20mm porcelain patio tiles and looks like its hardly worn. That was using a dribble of water from the hose for cooling for every hole, and running on a cordless makita grinder tool.The only niggle which I came across on the first hole was the wax, it's actually a PITA on a larger diameter bits like this. I quickly drilled and melted it all out of the bit. It's logical really that there is nowhere for the waste pellet of porcelian that's being drilled out to go. This is likely not so much of a problem on the small bit sizes where the porcelain is ground down to dust. After every hole you quickly suss out a technique to punch out the waste pellet wedged in there before cracking on with the next hole.Would I buy this again, yes, absolutely.

Speed.

drilled 5 holes in porcelain tiles not very good as described

20mm core - having always used Rubi for porcelain tiles (I fit bathrooms) I thought I would try a cheaper core bit as a comparison.Not only did the Rubi cut through the 10mm thick tile about 5 times faster, it still looked fresh.The cheaper option already showed signs of wear after only one hole.I will be sticking with Rubi going forward - although expensive - you do indeed get what you pay for in this instance.

Bit worked a treat. Used on thick porcelain tiles and done a great job. So far it's done about 15 holes and has life left in it. This won't last forever but it's perfect for projects and a small price to pay for what it does, just bear in mind you must cool it with water as you drill. Do that and it will last and do a fast, smooth job. Just use an old spray bottle or similar and job done.

Great
