Rated 2 out of 5Â by BigDez Not worth the money
I previously used the Erbauer diamond drills (I bought 2) for 9mm thick porcelain tiles and managed 7 or 8 holes per drill before wearing out. I decided to try these more expensive drills as I had a complete bathroom to kit out but the result was exactly the same, 7 or 8 holes then worn out. They are definitely not worth the extra cost.

Rated 5 out of 5Â by Shonkos Quality Drill Bit!
I started with a lower price drill bit and it just didn't cut the mustard!
Followed the instructions to the letter and this was a perfect bit of kit to use! 12 holes through 9mm porcelain and still going strong.

I had a number of holes to drill in porcelain tiles so decided to splash out on their most expensive. Unfortunately after 4 holes the drill bit was blunt, way short of the advertised 30 ~ 80 holes.
Good on Screwfix who refunded my money and I was able to buy the cheaper Erbauer version which lasted more than 10 holes.

Clean holes with no cracked tiles. Only managed 7 holes before bit showed signs of wear.
