Cratex
®
A tough, resilient, rubberized abrasive made
of silicon carbide grains evenly dispersed in
premium-grade, oil-resistant chemical rub-
ber. Features unique cushion action that
allows abrasive grains to cut freely, smooth-
ly and softly without gouging the work sur-
face. Resists clogging for high efficiency.
Ideal for a broad range of applications in
which metallic or nonmetallic surfaces must
be smoothed and polished without loss of
dimensional tolerances. Can be used with
water or typical shop coolants. Will not
harden or soften in storage.
