Now featuring ArmorGlide Technology, the Powermatic 1285T 12-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. This model features a straight knife cutterhead.
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.
Durable coating:ArmorGlide tables can withstand 250,000 passes without showing signs of wear.
