disk
Fabricated entirely with sisal strips cut at 45°, joined by a thick
stitches, this article is characterized by its long duration and
elevated abrasive power; the consumption is gradual and uniform along
the whole surface. The width of the central belt fastener must guarantee
a strong hold from the cloth, without creating width at the inside of
the wheel, in particular in case of a use of side by side disks; the
resin treatment, very frequent, amplifies duration and abrasion in the
