About Cylinder Burs (SA)

Often used as an alternative to a file, these burs have a long cylindrical shape with no cutting flutes on the end. They are ideal for general deburring and finishing of flat and interior contoured surfaces. Cylinder is the most commonly used bur shape. All have carbide heads, which are both strong and tough.

Rapidly remove steel, stainless steel, and other high-strength ferrous metals and alloys while leaving a smoother finish than single-cut burs. The double-cut flutes also create smaller chips than single-cut flutes and allow for more control of the bur and tool while operating.
