Does anyone here know about rotary tool bits? Possibly jewellers

[Binglebong]

I'm looking for son new diamond burr tips, similar to pictured. But I want some that will last as I'm drilling through stones for jewellery. Sadly not diamond toughness but still pretty hard!

Any suggestions?

Those ones are a waste of money. Get onto eternal tools for their diamond drill bits, they are a bit more expensive but they last a hell of a lot longer.

I use them when I'm drilling glass, I've previously wasted a lot on inferior bits until I discovered these people.

Agree...amazon and ebay stuff is useless...have you tried the shop in hatton garden....i think they do mail order....cant remember the name of it right now...!!...sell tools etc.

Thank you both. I got cheap ones to test if a plan worked - it did but I would spend a hell of a lot on replacements if I carried on using the cheap tools.

Cookson ...hatton garden...just remembered...also another shop nearby.

I bought mine from cookson gold. It was some years ago now but they probably still sell them. Never had any issues.

Thank journey for your help. Trying to work out sizes then I will order. 😀

Thank you for your help. But hey, cheers any journeys that want to help too.
