ry which in turn causes the uncontrolled
power tool to be forced in the direction oppo-
site of the accessory's rotation.
For example, if an abrasive wheel is snagged
or pinched by the workpiece, the edge of the
wheel that is entering into the pinch point can
dig into the surface of the material causing
the wheel to climb out or kick out. The wheel
may either jump toward or away from the op-
erator, depending on direction of the wheel's
movement at the point of pinching. Abrasive
wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse
and/or incorrect operating procedures or con-
ditions and can be avoided by taking proper
precautions as given below.
a)
operator can control kickback forces, if
proper precautions are taken.
b)
sharp edges or bouncing have a tendency
to snag the rotating accessory and cause
loss of control or kickback.
c)
Such blades create frequent kickback and
loss of control.
d)
Feeding the tool in the wrong di-
rection causes the cutting edge of the bit
to climb out of the work and pull the tool in
the direction of this feed.
e)
These wheels will grab if they
become slightly canted in the groove, and
can kickback. When a cut-off wheel grabs,
the wheel itself usually breaks. When a ro-
tary file, high-speed cutter or tungsten car-
bide cutter grabs, it may jump from the
groove and you could lose control of the
tool.
a)
intended for peripheral grinding, side
forces applied to these wheels may cause
them to shatter.
b)
mandrels will reduce the possibility of
breakage.
The c)
stressing the wheel increases the loading
and susceptibility to twisting or snagging
Corners, of the wheel in the cut and the possibility of
kickback or wheel breakage.
d)
the wheel, at the point of operation, is
moving away from your hand, the possi-
ble kickback may propel the spinning
wheel and the power tool directly at you.
e)
gate and take corrective action to elimi-
nate the cause of wheel pinching or snag-
ging.
f)
Abrasive cut-off wheels are
