Views of a damaged "High-Speed-Steel" bur =>7 photos

 In this essay, I will show only damaged HSS burs. In the next essay I will write how they can be repaired with some degree of skill & knowledge.

=======================

 The edge of the teeth has been damaged beyond in being used again successfully. The corners have been totally worn away but can be repaired with little effort.

 

 The bur corners have been in contact with a metal that changes the shape of the cutting edges.

  Constant wearing of the edges of the teeth renders the cutting action to be unsafe & unusable. In this case, please select another same size of bur from your inventory.

  Your selected bur will cut into the metal with little effort, why is this? The teeth have been kept sharp and constantly ready for advanced gemstone setting.

  If the bur teeth have been chipped or worn, the results could be catastrophic.

 THIS IS THE EPITOME OF A TERRIBLY DAMAGED BUR. Observe the damaged teeth, sometimes a bur like this can't be successfully repaired.

                                            -----------------------------------------------

 In the next following tutorial essay, I MIGHT BE ABLE TO REPAIR THIS BUR, BUT IT CAN BE SAVED ONLY BY REDUCING THE OVERALL MILLIMETER SIZE (anything is possible with certain limitations).
