Mandrels
A mandrel is a shank with a threaded or
screw head, and mandrels are required when
you use polishing accessories, cutting
wheels, sanding discs, and polishing points
The reason mandrels are used is that sanding

must be replaced frequently The mandrel is a

only the worn head when necessary, thus
saving the expense of replacing the shaft
each time

operating speed for at
least one minute before using wheel.
During this time no one is to stand in front
or in line with the brush, do not run in
excess of 15,000 RPM.
Cutting Wheels
These thin discs of emery or fiberglass are
used for slicing, cutting off and similar
operations Use them for cutting off frozen
boft heads and nuts, or to resIot a screw head
which has become so damaged that the
screwdriver won't work in it..Fine for cutting

cutting rectangular holes in sheet metaf
_When using steel saws,
cutoff wheels, high speed
cutters or tungsten carbide cutters,
always have the work securely clamped,
Never attempt to hold the work with one
hand while using any of these
accessories, The reason is that these
wheels will grab if they become slightly
canted in the groove, and can kickback
causing loss of control resulting in
serious injury. Your second hand should
be used to steady and guide the hand
holding the tool. When a cutoff wheel
grabs, the wheel itself usually breaks°
When the steel saws, high speed cutter or
tungsten carbide cutter grab, it may jump
from the groove and you could lose
control of the tool.
