Carbide Burs - One of the Most Versatile
Metal Working Tools
A bur is a rotary cutting tool with a tungsten carbide head of various shapes to form, reduce,
shape, smooth or clean pieces of metal. Burs are used in virtually every industry for mold and
pattern making, die sinking, tool making, maintenance, weld removal & casting flash removal.
They are used in automotive, aerospace, foundry, power station, ship building and engineering
industries. Champion carries dozens of styles of burs. Please refer to our website at

Most Popular Shapes of Bur Heads
Three factors to consider

Best Style of Bur for Non-Ferrous Materials
Non-ferrous burs feature deeper single-cut flutes which shear non-ferrous
materials (e.g. aluminum) into chips which are easily disposed of.
When to Use a Double Cut Bur
These burs have chisel type cutting edges with left and right hand spirals,
providing excellent stock removal, fine surface finish, and excellent operator
control.

Basic Usage Guidelines
Burs should only be run in electric or air die-grinders, which generally run from 15,000 – 25,000 rpm and higher. Burs should never be used in portable
drill motors (power tools). Conventional drills run much too slowly for burs which will cause chipping. Do not use worn out die-grinders which can also
cause chipping. Always apply constant pressure and steady action for best results.
