The tool should be running in a
spindle with the cutting blade in the
extended position. The tool is fed
into the workpiece. The burr on the
outer edge of the first wall is quickly
and easily removed.
2.The sliding sleeve is moved
backwards to retract the blade. The
workpiece is advanced to such a
position that, when the blade is again
extended by a forward movement of
the sleeve, it will lie between the two
walls. The burr on the inner edge of
the first wall is then easily removed.
3.Continued advancement of the tool
allows the inner edge of the second
wall to be deburred. The sleeve is
moved backwards once again to
retract the blade so that it can pass
through the hole in the second wall.
The blade is again extended to
deburr the outer edge of the second wall.
