The router is a versatile portable power tool that
can be used free hand or with jigs and attachments.
Figure 3-21 shows a router typical of most models. It
consists of a motor containing a chuck into which the
router bits are attached. The motor slides into the
base in a vertical position. By means of the depth
adjustment ring, easy regulation of the depth of a cut
is possible. Routers vary in size from 1/4 to 2 1/2
horsepower, and the motor speed varies from 18,000
to 27,000 rpm.
One of the most practical accessories for the
router is the edge guide. It is used to guide the router
in a straight line along the edge of the board. The
edge guide is particularly useful for cutting grooves
on long pieces of lumber. The two rods on the edge
guide slip into the two holes provided on the router
base. The edge guide can be adjusted to move in or
out along the two rods to obtain the desired lateral
There are two classifications of router bits.
Built-in, shank-type bits fit into the chuck of the
router. Screw-type bits have a threaded hole through
the center of the cutting head, which allows the
cutting head to be screwed to the shank. Figure 3-22
shows a few of the most common router bits.
