The Black Series Planer Jig is designed for most stationary
planers with 3 bladed steel cutter heads UP to 18 inches wide.
An on-board precision dial indicator lets you visually set your planer
blades to within 0.001 inches (1/1000 inches), insuring glass smooth
results from your planer. A powerful rare earth magnet secures the
Planer Jig to the steel cutter head while you monitor and adjust the
planer blades to perfection. Planer blade adjustment and replacement
is fast and easy with the Planer Blade Setting Jig
