You don't know how good these are until you've tried them! Forget filing and sanding you will be amazed how quickly these will remove a lot of material.

Expect to pay $45 - $65 for the same thing at a Trade Outlet.

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 and the double cut reduces the burr pulling into the work. 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

IMPORTANT Only at high speeds can their performance be realised. Electric drills are not fast enough, you need a die grinder or router. Use a lubricant when grinding sticky metals such as aluminium, lanolin works well. Also called a rotary file.
