uxcell Tungsten Carbide Files Rotary 1/8" Shank
Versatile Use: Widely used for metalwork, tool making, model engineering, wood carving, welding, casting, deburring, grinding, sculpting
The uxcell double-cut rotary files are tough enough for the hardest materials and last long enough to get plenty of use out of them. The files have a sharp edge, and we found that they were easy to work with. They also left a clean, smooth finish on wood, plastic, and aluminum. The files were easy to install in our rotary die grinder, and while we didn't try other types of rotary tools, we think they would be compatible with most any rotary tool. The files also have a small cutting angle, so they aren't quite as versatile as some other files, but we found that they worked well on most of our materials. Overall, we found the uxcell rotary files to be well worth the investment.

uxcell Tungsten Carbide Files Rotary 1/8" Shank
Versatile Use: Widely used for metalwork, tool making, model engineering, wood carving, jewelry making,welding, chamfering, casting, deburring, grinding, sculpting
These tungsten carbide rotary files cut through wood, soft metals, and plastic, and they're perfect for polishing. They come with a double-cut design, which is helpful for dense materials like wood, plastic, and aluminum. The files are sharp and sturdy, and they last a long time. The double-cut design also makes them more tricky to use than standard single-cut rotary files. The files aren't particularly expensive, but they add weight and bulk to a tool belt, and they're not particularly light. The files also aren't particularly sharp, so you may need to file the tips down after using them a few times. But if you need files that can cut through dense materials, and are occasionally polishing metal, these are among the best rotary files (and best rotary files for the money) around.

And it can handle both hard and soft metals, including steel, cast iron, and aluminum. The file's 1-inch length of cut is long enough to make full profiles, but short enough that it's quick and effortless to reposition after removing a file. The SB-5 even has a chamfering function, which is useful for creating smooth bevels on metal surfaces. A helpful tip: If filing carbon steel, clamp the file in a vise and press down the handle to compress the file's spring. This will give the file more cutting power, and the file will stay sharp longer.
