FIBER STONES FOR ALUMINUM
This is a new fiber-bond mounted wheel
developed by Norton Abrasives.
It was designed to clean up aluminum castings in
foundries. It is not a rotary file for porting, but
does a real good job of replacing sanding rolls for
cleaning up and smoothing ports and manifolds.
Use with WD-40
Stones are available in ½” & 5/8” diameter
1” long ~ all have a 4” shank
