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).
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
Taper with radius end
Head 28mm x 12mm diameter
Shank 6.0mm diameter
Overall length 68mm
Double cut profile
USE ON MATERIALS
Hardened steel up to HRC65
Cylinder head porting
Welding spatter clean up
Carving and sculpting
RECOMMENDED OPERATING SPEEDS
Burr Size Recommended rpm
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.
