What are "1/2 round" burs? (ver. #1) => 9 photos.

             What are "1/2 round" burs?

 These burs are shaped in this manner for several reasons & here are some of their uses discussed in this essay.

 

 Every bur that I use for "Cabochon Setting" was specifically shaped on my bench grinder for only one purpose.

 Each of my 'chosen round burs' was contoured, and these were kept separate from the rest of my round bur collection. In essence, I have two sets of round burs.

 These strange-looking burs are what make our jewellery lives so-o interesting. These are specifically made for creating seats inside a tube setting for Cabochon stones.

 These burs will create a seat inside any piece of new jewellery. The size of these burs are designed just for the size of the stone.

   My inventory of these "1/2 round" burs exceeds at about 30-40 burs.

  Here are a few of the burs that will be required for this tube setting. For your information, these burs might differ by 0.25 mm, as the exact stone size determines the size of the bur.

  This large, round bur size can be altered just by grinding off more metal from the tip.

 From this photo, you can easily see the shape of the intended Cabochon stone being made ready for setting.
