Tungsten carbide rotary burrs have a wide range of applications when machining mild steel, carbon steel, cast iron, stainless steel and aluminium etc. They remove material many times faster than traditional hand files allowing for increased productivity. They are for use in electric or air powered die grinders and some routers (where the router can be removed from the base).
ADVANTAGES
50 times the life of emery wheels
10 times the life of high speed steel burrs
5 times faster material removal than emery wheels
Doesn't make lots of dust like emery wheels do

NOTES
Only at high speeds can their performance be realised. Electric drills are not fast enough.
Use a lubricant when grinding sticky metals such as aluminium.
Also called a rotary file.
