Chris, and all !!!
It's not the number of burs you have to worry about. It's the
detailed selection you should be concerned with. Out of 1000 burs, if
one bur is all you require at that moment in setting. Then you've
made your day. Job is done without postponing the setting till the
tool supplier opens up. I usually set aside three burs; why? Glad you
asked, one for the exact size. One for a tad larger, and another for
opening up the Pavillion of the stone....Hence, three burs for ONE
Even to continue, if I have one used bur, the measurements are then
being reduced...keep it! Use it for a slightly smaller stone. Now you
have a bur that is NOW just in between the "two bur, stock sizes".
Lets say a spread of 1.75 mm and a 2.00mm now you might have a used
bur of 1.90mm or 1.85mm, great? I only throw away a bur if all of the
teeth are totally worn down. Some tool suppliers may not have a 1.85
or a 1.95mm...but YOU DO NOW!...:>) Also if the teeth are slightly
worn down, I use this bur for a mini-file for in-between beads, or
finishing off of an under section for an Azure area of the ring.
Nothing is wasted on my setting bench, free to use it as
