I know burs are not cheap, but if you are buying a whole bunch, you
should ask for a 10% discount for a large quantity. Don't be bashful,
discounts are there, if you are a big time buyer..at one trip! Some
years ago I bought over $4,000 in burs alone..in one single fiscal
The aforementioned #006 sizes should be used as delicately as
possible, these sizes/burs never get within range of any gemstone.
Cup burs a.k.a. #77B, are the most expensive but useful. Rounding of
center stone claws or even the smallest multi-stone ring. They are
much needed, don't be watching all the time for the dollar.
My rule of thumb, is to buy a "6-pack" of every possible size or
possibly a dozen, if used often...Once I bought a 6-pack of some very
large cup burs, and for these 6 cost me over $66.00 plus taxes. Let
me tell you all why? I had some rather small tube settings to round
off equally. So I invested in these 77B> #040 size, while the other
setters were struggling to make their tubes look half decent, mine
were cleaned in nano-seconds and looking like they were meant to be.
Clean, round, & even thickness of metal.
Once you decide to buy most of my previously mentioned sizes,
experiment with all possible uses. I use my little bud burs as
"mini-files". Inside of baguette bezels, inside of tube settings,
opening up Gypsy setting holes, tapering off the deep stone pavilion
metal settings..basically everywhere! These uses are endless...HAVE
