Sandpaper Selection
sanding a workpiece smooth requires using pro-
gressively smaller grit sandpaper until the desired
finish is attained.
the abrasiveness of sandpaper is designated
in grit size—the larger the number, the finer the
abrasive and the smaller the scratches. thus, 100
grit is finer than 60 grit.
typically, sanding operations start with a coarse
grit and progressively work through the finer
(larger number) grits until the desired finish is
achieved. avoid skipping a grit to achieve the best
results.
Choosing the correct grits involve many factors,
such as the workpiece condition, type/hardness,
and the desired finish.
there are many types of sanding belts and discs
to choose from. We recommend aluminum oxide
for general workshop environments. Below is a
chart that groups abrasives into different classes
and shows which grits fall into each class.
Grit Class Usage
36 extra Coarse rough sawn boards,
thickness sanding,
and glue removal.
60 Coarse thickness sanding
and glue removal.
80–100 medium removing planer
marks and initial fin-
ish sanding.
120–180 Fine Finish sanding.
To ensure good sanding results, never skip
more than 50 grit with each sandpaper
change.
the model g1183/g1276 ships with a pre-installed
80-grit, 6" x 48" sanding belt.
