2.
Clean any debris or surface substances from
inside spindle taper and mating surface of
tooling.
Note: Debris or oily substances can prevent
tooling and spindle from properly mating. This
condition can cause excessive vibration, poor
cutting results, or tool/workpiece damage.
3.
Align tooling keyway with pin inside spindle
taper, then firmly push tooling into spindle to
seat it.
Cutting tools are sharp and can easily
cause laceration injuries. Use heavy leather
gloves or shop rags to protect your hands
when handling cutting tools.

With one hand holding tooling in place, insert
vertical drawbar (longer of two drawbars) into
spindle from top of head, then thread it into
tooling (see Figure 38).
Note: Drawbar has an adjustment hex nut
(see Figure 38) that is used to raise/lower
drawbar to compensate for different tooling
lengths.

Tighten drawbar until it is snug. Avoid over-
tightening, as this could make removing tool-
ing difficult later.

top of it with a brass hammer to knock taper
between spindle and tooling loose.
