Powermatic 16" Parallelogram Helical Cutterhead Jointer with ArmorGlide 7.5hp, 3PH, 230V - PM1-1791283T

Powermatic 16" Parallelogram Helical Cutterhead Jointer with ArmorGlide 7.5hp, 3PH, 230V - PM1-1791283T

Now featuring ArmorGlide Technology, the Powermatic PJ1696T 16-Inch Jointer offers big capacity and performance in a machine loaded with features. A large center-mounted fence assembly adjusts easily by a rack and pinion system with ram lock. Preset stops on the fence body allow for fast angle set-up at 45° in and out, and a positive stop for perfect 90° angles.

The parallelogram design keeps the table in close proximity to the cutterhead for improved finish and allows for a fast depth of cut adjustment. This design also ensures the tables remain perfectly parallel even after years of tough duty.

The specially-designed solid steel helical cutterhead consists of six rows of precision-ground staggered inserts. This system makes fast work of knife changing, and never needs adjustments. The heavy-duty 7.5hp motor delivers all the power you need for even the biggest jobs.

• Enhanced visibility: The dark surface reduces glare, so you can see where you're cutting better.
• Rust resistant: Ditch the steel wool and never worry about rust again.
• Low friction: Coated tables require 50% less force, so you get more control.
• Maintenance-free: Get rid of the waxes and messy cleaning supplies, so you can do more of what you love.
