Great product. It got me out of a fix as I needed a hole in a toughened glass mirror for a door handle. I fitted it in a 1/4 trim router with a coke can shim to make up the slight difference in diameter, this allowed me to spin it at 35000 rpm. I then squirted a few drops of water and it cut my hole with no issues. It saved me £70 on a new mirror. Brilliant piece of kit!

Well what can I say absolutely fantastic drilled 10 holes with just one bit into porcelain tiles 10mm thick using water 💧 using syringe and cleaning diamond bit head every 15 seconds 😀Definitely listening to all reviews and tips helpful getting your mileage out of just one 5 star Definitely 🌟 start of slowly keeping it on a tilt then straighten up once made an impression

Drills work but you will need several to make an impression on hard stone.

I needed to drill some holes in external porcelain slabs to add lights to them. I bought a Marcrist bit from Screwfix for £30, which only managed to drill one and a half holes. I bought the pack of 10, 6mm bits from here. Thinking I could finish the job if one bit did one hole each. But one bit finished the second hole I had started as well as the remaining 6 I needed to do. Fantastic bits for 1/15th the price.

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

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

These are quality drill bits

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.
