Using Burs
A tool commonly used in stonesetting to cut a seat for the gemstone or diamond is a bur.
Use light even pressure when you are using burs. Excessive pressure to vigorously cut metal will overheat the burs. This heat will remove the temper from the tool and it will no longer be able to keep a sharp cutting edge. Let the tool do the work. DO NOT USE EXCESSIVE SPEED OR PRESSURE TO FORCE A DULL BUR.
