Spindle Downfeed

Qty
Spindle downfeed movement on the drill press
is controlled by two mechanisms: 1) The coarse
downfeed lever, and 2) the fine downfeed
handwheel (see Figure 46). Refer to Controls &
Components on Page 4 for detailed descriptions
of all downfeed controls and components.

Using Coarse Downfeed
Coarse downfeed is typically used for drilling,
because it allows you to quickly lower the spindle
with varying speed/pressure, and it automatically
retracts the spindle back to the top position when
released.
To engage coarse downfeed, make sure the
spindle is completely stopped, and loosen the
downfeed selector knob (see Figure 46).
Note: To maintain control of the upward spin-
dle travel, always continue holding the coarse
downfeed levers until the spindle returns to the
top position. Letting go of the levers too soon will
cause the spindle to retract too quickly and slam
up into the headstock.
