"Brought this to drill through 10ml porcelain tiles. After burning out 2 masonry drill bits and 1 'tile' drill bit I decided that I needed to invest in something a little stronger. I cant rate this drill bit enough it worked brilliantly."

"We bought this bit to drill through very expensive floor tiles, and fit a toilet. It was was not the cheapest one available, but there are no second chances when drilling a tile. It worked fantasticlly, most impressed."

Best solution by far

"After fitting lovely porcelain tiles in my en suite, I quickly realised how hard they are to drill!
After looking at bits I could not find anything under £30 . I spotted this one at half price, I was expecting to have to buy another one or two but as usual Dewalt's quality shone through, drilled 14 x 7mm holes in 10mm thick tiles and the bit seems to have plenty of life left. Yes the water reservoir is a faff, I used a spray bottle.
Porcelain is one tough material and drilling takes time, patience wins the day! excellent."

"Now were talking! This cuts through the toughest tiles, it works a treat.
Bit expensive though, other ones on the market that are cheaper, as this has the Diwalt label on it!

Bit disappointed
19 Mar 2010

"I destroyed a couple of "regular" tile drill bits cutting thru thick porcelain tiles, and realised I needed something more effective.
Let me say that the bit itself does get thru the tiles, eventually.
The biggest problem is establishing the initial cut in the right place, when using on a wall. The water bath suckers are useless to keep the drill bit in place. The drill tip is "flat"and it is difficult to target a specific point initially, and the water bath skids off out of place. This is made worse by the water delivery, which works to a point. The first few attempts, localised water made a right mess compounding the slipping, and rendering the suckers inoperable until the area was properly dried again.
I found I had to use the drill bit at about 45deg on its own to establish a "key" and pierce the tiles so the bit wouldn't slip. Once I did this, I used a garden water spray, and did the drilling in a few slow, gentle bursts, and it did get thru the tile far easier than with previous bits.
The bit does the job, but is difficult to use without a little DIY tweaking. The water bath is useless."
