There are many types of sanding belts to choose
from. We recommend aluminum oxide for general
workshop environments. Figure 17 lists groups of
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 finish sanding.
120–180 Fine Finish sanding.
Figure 17. Sandpaper usage chart.
The general rule of thumb is to sand a workpiece
with progressively higher grit numbers, with no
one grit increase of more than 50. Avoid skipping
grits; the larger the grit increase, the harder it will
be to remove the scratches from the previous
grit.
Ultimately, the type of wood you use and your
stage of finish will determine the best grit types to
install on your sander.
