The charts shown on GX^\)' & GX^\)( are intended as
guides only. Always follow the manufacturer's speed rec-
ommendations if provided with your drill bits, cutters, or
hole saws. Exceeding the recommended speeds may be
dangerous.
The speeds shown are intended to get you started. The
optimum speed will always depend on various factors,
including tool diameter, drilling pressure, material hard-
ness, material quality, and desired finish.

The belts in the head of the drill press must be rear-
ranged to change speeds. A chart under the belt cover
shows the belt positions needed to make the drill press
run at the desired speed.
