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.

Selecting theCOUNTERSINKS Right Bur ZERO FLUTE Most Popular Shapes of Bur Heads Three factors to consider 1. Shape of work piece being de-burred determines shape of bur chosen 2. Area being de-burred determines size of bur needed 3. Material being de-burred determines double-cut or non-ferrous flute style. SA - Cylinder Shape SC - Cylinder Radius Shape SD - Ball Shape SF - Tree Shape Radius End Bur Styles Double Cut Non-Ferrous Long Series Miniature 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. 2 New Champion Bur Styles (Available 1st Qtr 2015) Combi Bur Radius Bur SD5CO Exclusive new shape engineered for deburring, edging and blending with a single bur.

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. www.championcuttingtool.com
