Panel Saws
Sometimes, large sheets of plywood or other
polymeric material must be cut into sections. While
this can be done on the table saw, it is often easier
to use another type of saw called a panel saw. See
Figure 21-22. The panel saw consists of a circular saw
attached to steel rails that are suspended over a rack
that supports the material to be cut. The saw slides
up and down easily on the rails, and can be turned to
cut the sheet either vertically or horizontally.
Drilling
Most readers will be familiar with the process
of drilling holes with drill bits using hand drills
or machine drill presses. However, there are many
different ways to make holes in wood.
Machine drilling, or boring, of holes in wood
is normally done with a drill press or a boring
machine. The tools that are used to produce holes are
called bits. They are held in place in the drill press
by clamping them in a chuck or by inserting them in
a tapered sleeve.
In addition to common drill bits (usually referred
to as “twist drills”), other cutting tools are available,
such as plug cutters, Forstner bits, hole saws, auger
bits, and spur machine bits. Holes 1/4″ (6.3 mm)
or smaller in diameter are normally drilled with a
handheld power drill, a manually operated rotary
drill, or a push drill. Any of these tools will drill
small holes quickly. Larger holes are usually made
with a drill press, Figure 21-23. The operator in the
photo is checking the positioning of the workpiece
before starting to drill the hole. Note the large bit,
which has a tapered shank that is inserted in a sleeve
attached to the drill press spindle. To ensure accurate
and safe operation, the workpiece is held securely in
a fixture bolted to the table of the drill press.
Figure 21-21. The miter saw, or power miter box, can be
used to cut trim and molding stock at compound (both
horizontal and vertical) angles. A spring loaded arm keeps
the saw off the work until it is pulled down by the operator.

large sheets of plywood or similar materials into smaller
pieces. The saw can be rotated to cut either horizontally or
vertically. (Black and Decker)
