These spiral cutterheads are designed to replace
the straight knife cutterheads from most Grizzly 6"
and 8" jointers.
The total procedure of changing the cutterheads
and setting up the jointer takes approximately
one hour. The job consists of removing the old
cutterhead, installing and shimming the new spi-
ral cutterhead, and readjusting the outfeed table
even with the knife edges at TDC (top dead cen-
ter). Call Technical Support at (570) 546-9663 if
you need help.
