"Bought this (and the 6mm version) to drill through 12mm polished porcelain floor tiles, slightly in desperation after my normal tile drill has failed to penetrate even 1mm after 20mins of careful drilling.
Drilled the first hole in less than a minute, no problem. Successive holes each took slightly longer and longer as I guess the tip started to wear, but still looks good to drill more after 6 holes.
The drill instructions say to use dry, which is what I did i.e. I did not wet the tiip (up to you what you do though). Although I was hesitant to follow the instructions to run the drill at a very high speed, I quickly found that slow speed drilling was a lot less effective, and so ran the drill at the recommended higher speed - taking care to air cool it every so often to avoid cracking the tile
In summary, yes it is expensive, but well worth it - I would recommend this product!"
"This tile drill easily cut through my floor tiles. Although instructions said to cut dry, I dipped tip in cold water evry 30 secs or so and did job brilliantly. Still plenty of life in it yet after cutting 6 holes thru 19mm tiles. Srewfix win again with quality and great value."
"I had done a bit of research on how to drill through thick floor tiles and the main anticipated problem was causing the tiles to crack by the friction overheating.
Some other drill bits required water or oil application to keep them cool to avoid this and I knew this could get messy!
I was delighted to see that the Erbauer 8mm drill bit did not need any cooling/lubrication during use, and decided to spend the extra money on the diamond variety.
With some trepidation I began the drilling process but was delighted to see the head disappearing into the 10mm thick porcelain tiles without any fuss or big mess. I didn't need to apply any more than a light pressure to achieve a clean cut - a quick vacuum of the dry debris and job done!
As another user mentioned - the bit looked just as good at the end of 5 deep cuts as when it started, and I would certainly invest in another one of these when the time (eventually) comes."
"The drill bit does not melt at high speeds like others do. It does not need water. Debris can be tapped off easily and have used it on ceramic tiles and still going strong after 10 holes. Other s lasted 2-3 holes before going blunt/melting."
"Before buying this drill I bought the dewalt diamond tipped drill bit which took 30 mins to drill a single hole in grade 5 porcelain tiles, and required continuous water cooling. The Erbauer was night and day different, straight through the tile within 3 mins and without the need of water spray, I drilled several more holes and its still like new."
"I needed to drill 8 holes through some heavy duty tiles . Having tried masonary drills and cheaper tile drills , all of which made no impression on the tile , I bought Erbauer Diamond tile cutter. I had been put off by the price as I may not use it again. However having no other options I gave it a go. Thankfully it worked . I used a drill stand to get the hole as accurate as possible. The drill went through the tiles with no problem although by the fourth hole it was smoking quite a bit. Had it have been cheaper I would have given it 5 stars."
"At last I've found a drill that works on hard porcelain tiles. Only drilled 3 holes so far but it was quick, trouble free and the drill bit looks just the same as when I started. Might be expensive but gets cheaper each hole you drill."
It did a good job with most holes very clean. I used theErbauer guide with it and it definitely helped. Need to apply a bit of pressure behind the. Drill but it works it's way through the tile pretty well. Have used other brands and among the best I've used.
I found that the bits were getting hot and smoking a bit so would run the, under the tap briefly.
Not used on any other materials yet and not had enough use to comment on reliability but so far so good."
