They are used to remove excess material or flashings; or simply to shape, grind, cut and clean areas on steel, steel castings, aluminum, copper and other ferrous and non-ferrous metals. The carbide burs can also be used on reinforced plastics, hardened enamel, stone, porcelain, hardwood and ceramics. Carbide Bur applications would be deburring, shaping, cleaning and smoothing materials. The bur must be used at high speed for the tool to work properly. It should never be “forced” with pressure; but rather the bur should be used gently so that the serrations can do the cutting rather than the pressure. Double Cut Applications For removal of smaller amounts of material on Steel, Steel Castings and Non-Ferrous metals. Also can be used at slower speed; affording better operator control. Carbide Burs vs. High Speed Steel For best results, Tungsten Carbide is an extremely hard material and should be used in much more demanding applications than your average high speed steel bur. They are also much more costly than high speed steel burs; and therefore will be underused if you are using them in an application where a high speed steel bur will work just fine for the job. Carbide Bur Speeds Rating Carbide Burs should not exceed 35,000 RPM. The bur can chip easily if the speed is too slow. It is most ideal to start cutting slowly at the beginning and to increase the speed as you handle the tool on the piece work. Higher speeds prevent clogging of the bur flutes. Best Usage Methods The bur should be moved slowly but continuously to prevent the bur from jabbing or digging into the work. End the work with an up-stroke motion, which will give the work an attractive, smooth finish. For removal heavy amounts of material on Steel, Steel Castings and Non-Ferrous metals. © 2016 Wurth USA, Inc. Revision 02/2016 08.0580
