Figure 13-9.—Rivet-head shaver. 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 Figure 13-10.—Rivet gun internal airflow 13-6
