Are you struggling to joint wide boards accurately while maintaining consistent surface quality across long stock?
What if your jointer delivered smooth cuts, stable support, and repeatable accuracy on every pass?
Meet the Powermatic 1285, a 12-inch parallelogram jointer built for precision jointing and long-term reliability.

Powermatic 1285 for Wide-Board Jointing and Consistent Results
Parallelogram Table System for Long-Term Accuracy
The parallelogram design keeps the tables aligned with the cutterhead while allowing fast, precise depth-of-cut adjustments. This ensures consistent performance and accuracy even after years of heavy shop use.
84-Inch Cast Iron Bed for Large Workpieces
The long precision-ground cast iron table provides stable support for wide and heavy boards, improving jointing accuracy across the full 12-inch capacity.
Rack-and-Pinion Fence for Controlled Adjustments
The center-mounted fence uses a rack-and-pinion system for smooth positioning and includes preset stops at 45° and 90° for repeatable setups.
Flexible Cutterhead and Surface Options
Choose a straight knife cutterhead for traditional jointing and rabbeting capability, or a helical cutterhead with carbide inserts for reduced tear-out and quieter operation. ArmorGlide models add a low-friction, rust-resistant surface for improved material handling and reduced maintenance.
