Powermatic 12" Parallelogram Helical Cutterhead Jointer with ArmorGlide 3hp, 1PH, 230V - PM1-1791307T

Powermatic 12" Parallelogram Helical Cutterhead Jointer with ArmorGlide 3hp, 1PH, 230V - PM1-1791307T

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 helical 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.

Features

• ArmorGlide Technology gives you a low-friction, industrial-grade coating on the work surface that is rust resistant, requires less maintenance, and gives you more control
• Helical cutterhead features 42 two-sided carbide inserts for fast knife changes with no adjustments and a quiet, clean cut
• Large 12" x 84" precision ground cast iron table surface for heavy-duty work
• Parallelogram design ensures close table-to-cutterhead proximity and fast depth of cut adjustments
• Rack and pinion adjustable cast iron fence assembly allows for smooth fence positioning without play
• Table "lips" on both sides of cutterhead aid in noise reduction
