Bur Basics

Cylinder Burs can be used like a flat file. They can remove large amounts of material quickly. Large cylinder burs are useful for grinding the insides of ring shanks to increase their size.

High Speed Steel (HSS) burs strike a balance between cost and durability. They maintain their hardness (temper) better than vanadium steel and cost less than carbide steel.

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.
