Radial Bristle Discs
Long-lasting, nonloading abrasive discs
for cleaning, prepolishing, blending and
removing scratches and firescale. Color-
coded to denote grit, which is uniformly
dispersed. Require no compound, so
time-consuming cleanup is eliminated.
Allow you to work faster and neater. Max.
operating speed: 20,000rpm for 3" discs;
30,000rpm for all others. Recommended
speed for most applications: 15,000rpm.
See p. 131 for mandrels.
