Hold the tool firmly. Turn the tool on and then apply the
wheel or disc to the workpiece. In general, keep the
edge of the wheel or disc at an angle of about 15° to the
workpiece surface. During the break-in period with a
new wheel, do not work the tool in the B direction or it
will cut into the workpiece. Once the edge of the wheel
has been rounded off by use, the wheel may be worked
in both A and B directions.
