Edge Grinding and Cutting (Fig. N)

WARNING: Do not use edge grinding/cutting wheels
for surface grinding applications because these wheels
are not designed for side pressures encountered
with surface grinding. Wheel breakage and injury
may result.

CAUTION: Wheels used for edge grinding and
cutting may break or kick back if they bend or twist
while the tool is being used. In all edge grinding/
cutting operations, the open side of the guard must be
positioned away from the operator.
NOTICE: Edge grinding/cutting with a Type 27 wheel
must be limited to shallow cutting and notching—less
than 1/2" (13 mm) in depth when the wheel is new.
Reduce the depth of cutting/notching equal to the
reduction of the wheel radius as it wears down. Refer
to the Accessories Chart for more information. Edge
grinding/cutting with a Type 41 wheel requires usage
of a Type 1 guard.
1. Allow the tool to reach full speed before touching the
tool to the work surface.
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Grinding/cutting rate is
greatest when the tool operates at high speed.
3. Position yourself so that the open‑underside of the wheel
is facing away from you.
4. Once a cut is begun and a notch is established in the
workpiece, do not change the angle of the cut. Changing
the angle will cause the wheel to bend and may cause
wheel breakage. Edge grinding wheels are not designed
to withstand side pressures caused by bending.
5. Remove the tool from the work surface before turning
the tool off. Allow the tool to stop rotating before laying
it down.
