FITTING THE DRILL CHUCK SUPPLIED
To replace the arbor (A) with the drill chuck
supplied first remove the arbor.
To do this, using the spanners supplied, place
one spanner on the flats of the drill output
shaft.
Turn clockwise (as viewed from above) until
the spanner meets the dovetail slide.
Place the the second spanner on the flats of
the arbor, apply pressure, again clockwise as
viewed from above.
If possible the magnet can be used to hold
the machine whilst removing the arbor.
If the arbor is tight the spanner on the arbor
flats can be tapped with a soft mallet.
Once the arbor is unscrewed the arbor
support bracket (B) needs to be removed.
This is accomplished by removing the two
hexagon socket head cap screws.
To fit the drill chuck simply screw it into place
on the spindle nose.
A special left handed screw is provided to
hold the chuck.
Replacement of the arbor is a reversal of the
procedure above.
B
USING TWIST DRILLS
Twist drills can be used with the PB320.
To accommodate twist drills, or any plain
shank cutting tool, the PB320 is supplied as
standard with a 1/2” drill chuck and key.
The drill chuck takes standard parallel shank
twist drills of up to 1/16” - 1/2”, and if
required reduced shank drills of up to 11/16”
can be used.
