Rivet Head Shaver
The rivet-head shaver, shown in figure 13-9, is
used to smooth countersunk rivet heads that protrude.
The rivet head shaver is also called a “micro miller.”
The depth of cut is adjustable in increments of 0.0005
of an inch on the model shown. On some models the
depth of cut is adjustable in increments of 0.0008 of
an inch. You can change cutters and adjust their depth
without using special tools. Once the depth is set, the
positive action of the serrated adjustment locking
collar prevents the loss of the setting.
You should position the cutters directly over the
rivet head and hold the tool at an angle of 90 degrees
to the surface being smoothed. With the tool turning
at maximum rpm, you then press it in towards the
surface, maintaining the 90-degree angle. The
pressure feet will then be compressed until they
bottom out.
At this time, assuming the rivet-head
