Great diamond bitsSharp and work well on hard tiles.Size as described.

Very good quality drill bits used these professionally up to now can't fault them.

For the price these are excellent valueAs you can pay this for one decent bit. We drill a lot of porcelain and will be purchasing these again

I bought these to go thru Porcelain tiles. Having watched several videos on the subject I was informed that the bits would do a maximum of 4 holes. Unfortunatley I found they would only do 2 holes before they became impossible. In fact to do 8 holes I used 5 drill bits - this working out at £1.20 per hole, give or take.I used a classic type porcelain drill bit to start off the hole given that these are not that accurate and this system proved useful and I had no mishaps. So I am not sure about value for money

These are the best diamond tip drills I've bought to date, well made and sturdy... Much better than the bright silver ones that twist and break if they get jammed and usually only last about 2 minutes in any case. The hole down the middle of these is filled with wax for some reason which baffles me but thats not really a problem, just have to get it out before using them.

Now these bits were a lot better than I expected. The surface lasted the hole cutting and I was able to also grind some curved edges. The only trick was getting the plugs out from inside which wasn’t much of an issue. Pleasantly surprised how they chomped through some porcelain patio tiles and some artisan bathroom tiles for radiator fixings and copper pipe rad feeds without breaking a single tile. Would buy more but this set did all the jobs for wall hung loo, rads and sink pipes in a downstairs toilet with no issues.

I need diamond drill bits to drill into my porcelain tiles in the bathroom. These did the trick, made a speedy job of it.But you will only get one hole from each peice or 2 with hard work. But at the price I would say value for money.
