confusing title, not diamond

"It is a
"Diamond-ground, tungsten carbide drill bit "
Which is a big difference from a diamond tipped drill bit.
VERY misleading title"

Poor for Porcelain

"Takes an awfully long time in Porcelain
May be OK in Ceramic but not much better than good masonary bit for Porcelain.
Pay the extra for Porcelain bits."

Rubbish!
27 Nov 2013

"I bought this drill bit to drill into wall tiles. It was so bad I even had to check it was in the drill the right way round! It didn't cut into the tile at all. Suggest the DeWalt item sold by Screwfix (diamond head) which does however cut my tiles. I only wish Screwfix would listen to these reviews and either remove the item from sale or the shop assistant could advise me how I'd be waisting my money to buy this."

Don't even consider buying one
14 Jun 2013
By phaedrus

"I bought one of these bits to drill porcelain wall tiles, as it was described as suited for that purpose.
It was totally useless, nowhere near as good as a standard masonry bit which took about half an hour!
If you need to drill hard tiles, don't even consider this product, get a diamond core bit, I drilled 6 holes in five mins with one, using a constant dribble of water to cool it.
