I only use the alum carbide cutters if I want to remove
a good bit of material... I also have a support bearing
on my longer burrs so they dont fly around the port
if they bite too hard... with all the different grits
on the tootsie rolls you can hog or fine tune it to
be as aggressive as you want... I pick up boxes of
tootsie rolls in assorted grits from the local abrasive
company for alot less money.... I probably have 6-8
boxes of different grits and diameters right now
