how to choose tungsten carbide rotary burr？

If they are used for fine engraving of metal, such as engraving complex patterns and designs in mold and die making, then you need to choose a rotary file with a fine edge and a suitable shape (such as a bulbous or tapered). If it is used for removing burrs from the surface of large metal castings or roughing up the metal after welding, then you can choose larger sizes of rotary files with coarser cutting edges, such as those with cylindrical or square cutting edges, which are able to remove large quantities of material quickly.

For machining harder materials, such as hardened steel or carbide itself, carbide rotary burrs with high hardness and good wear resistance should be selected. The alloy composition of these rotary files usually contains more hard phases such as tungsten carbide, which is able to withstand the reaction force of high hardness materials and maintain the sharpness of the edge.

High-quality carbide rotary files have good performance in terms of density, hardness and toughness of the alloy. Zhuzhou Jinxin carbide rotary files are available in various shapes (cylindrical, ball-ended, conical, flat-ended), which can meet your different industries and needs.
