Cylinder Bur (Rotary File, Ring File)

The straight sides of this bur make it a good alternative to a file, especially when removing large amounts of material. Large diameter cylinder burs (up to 1/2” dia.) are primarily used for grinding the insides of ring shanks. Also available with a rounded end.

Cross-Cut Burs (many shapes available)

Cross-cut burs come in a variety of shapes. Instead of having fluted cutting surfaces like a typical bur, these burs have “teeth” similar to a double cut file. They are very agressive and used mostly for removin large amounts of material.
