and will stay engaged until either quill stop comes in
contact with micrometer adjusting nut, forcing feed
control lever to drop out automatically, or release
manually by engaging lever to right.

FEED CONTROL OVERLOAD CLUTCH

The Feed Control Overload Clutch is set at the

factory to hold up to 200 lbs of down pressure on
quill, which will accommodate drills up to .375”
diameter in mild tool steel.

This clutch should not be tampered
with in the field.
