³⁄₃₂" dia. shanks are the jeweler's preferred standard for burs and small rotary tools. They fit the adjustable chucks found on most flexshaft handpieces as well as ³⁄₃₂" handpiece collets.

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.

Wax Carving Burs feature widely-spaced cutting edges for aggressive material removal without clogging. They can also be used for carving wood and plastic.
