Bur Basics

Round Burs are useful for de-burring or enlarging holes, carving recesses for sweat soldering, and refining stone settings. Because of their shape they can be used at any angle.

1/8" dia. shanks are larger than the standard 3/32" tools most used by jewelers. These larger tools fit most adjustable chucks but will not fit most quick-change handpieces.
