I'm confused. So do you all agree with this statement of the link above?
1. Carbide burrs can be used on many materials
Tungsten Carbide burrs can be used on most hard materials: metals including steel, aluminum and cast iron, stone, ceramic, porcelain, hard wood, acrylics, fibreglass and reinforced plastics.
Different cuts of carbide burs will be best suited to certain materials, see the next point below to find out about the different cuts.
2. Carbide burrs commonly come in two cuts; single cut and double cut
Single cut (one flute) carbide burrs have a right handed (Up cut) spiral flute. These tend to be used with steel, copper, cast iron and ferrous metals and will remove material quickly with a smooth finish.
Double cut or Cross cut carbide burrs tend to be used on non ferrous metals, aluminum, soft steel, plastics and hard wood. Double cut or cross cut (2 flutes cut across each other) will leave a slightly smoother finish than single cut due to producing smaller chips as they cut away the material.
I am not understanding what they are saying.. a
alum burr has wide cutter on it(single cut)... I
will put up a link for both alum and steel/iron burrs..
a double cut is used on steel/iron
EDIT
When I'm doing alum I get it close with a single
cut burr.. then I fine tune it with a tootsie roll
thats medium to heavy grit(it will vary on how close
I was with the burr).... on iron I will get it a lot
closer with the burr(double cut burr) then fine tune
it with a course tootsie roll.. you can getthe burrs
in multiple styles and shapes... I like egg shape and
tree shape.. in different sizes and cuts
Also.. the carbide or tungsten carbide is just
the material its made out of.. you can get the same
burrs in either material
https://www.pferdusa.com/products/202b/index.htmlthis one is for steel.. its a double cut style

the chip off of each
