12-Inch Parallelogram Jointer, Helical, 3 HP, 230V 1Ph (1285HH)

The Powermatic 1285HH 12-inch parallelogram jointer with a helical cutterhead and 230V single-phase power is designed for professional shops seeking precision, surface quality, and long-term reliability. Powered by a 3 HP motor, this jointer delivers smooth cutting performance for jointing wide stock and hardwood materials. The helical cutterhead operates at speeds up to 5,000 RPM and uses multiple carbide inserts to reduce noise, minimize tear-out, and extend edge life compared to traditional straight knives. Its parallelogram table system keeps the tables close to the cutterhead for improved finish quality and allows quick, accurate depth-of-cut adjustments while maintaining table alignment over time. A large center-mounted fence adjusts smoothly via a rack-and-pinion mechanism with a ram lock, and preset stops allow fast positioning at 45 degrees in and out, as well as a positive stop at 90 degrees. Built with heavy-duty cast iron components, the 1285HH provides stability and vibration control for consistent results in demanding woodworking environments.
