Absolute c**p. This bit wore out before I had drilled one hole. I didn't see any point in opening the 7mm after that. These weren't cheap!
Got to say Screwfix handled it well, no problem with a refund. Actually I OldBoytook part refund and replacement hardened carbon steel (although called a diamond bit!) These did the job but quite slowly.

It still takes ages to drill holes with this bit. Drilled 4 holes in about an hour. After that it seems to go blunt and now I'm on hole number 5 and it's taken 30mins to get halfway through the tile so far.

Fantastic product. Drilled all holes within an hour after wasting hours with masonry bits all of which barely made a scratch..Diamonds are forever

Used the drill to drill four 8mm diameter holes in a 9mm thick porcelain tile. Followed Screwfix instructions. Drill lasted for less than three holes before useless, although it did work well for the first hole. Bought same again in a different store and had virtually identical experience.
