Note: Due to variables in tool diameter, coatings,
coolant, and materials, no specific spindle speed or
feed rate recommendations are provided. Use
general shop manuals that have data applicable to
the milling and drilling operations being performed;
or contact the supplier of the tooling, coolant, and
material for specific recommendations.
IMPORTANT: The power feed can be used for
drills up to 3/8” in diameter (mild steel). Use
manual feed for drills larger than 3/8”.
The overload clutch is factory
set to hold up to 200 lb. downfeed pressure on
the quill (accommodates drills up to 3/8”). Do
not attempt to adjust clutch pressure.
