Description
The Powermatic 1285HH 12-inch parallelogram jointer with a helical cutterhead and 230/460V three-phase power is built for industrial applications requiring continuous-duty performance and consistent surface quality. Driven by a 3 HP three-phase motor, this jointer provides smooth, uninterrupted power for processing large volumes of stock. The helical cutterhead, running at up to 5,000 RPM, delivers quieter operation and improved finish quality by using staggered carbide inserts that shear material cleanly. Its parallelogram table system keeps the cutterhead-to-table relationship precise while allowing quick depth adjustments without sacrificing alignment. The center-mounted fence adjusts easily using a rack-and-pinion mechanism and includes preset stops for fast, accurate angle changes. With heavy cast iron construction and a design focused on
Features
- 3 HP three-phase motor supports continuous-duty operation for production shops processing high volumes of material
- Helical cutterhead with 42 two-sided carbide inserts shears stock cleanly for reduced tear-out and longer cutting edge life
- Cutterhead speed up to 5,000 RPM delivers consistent surface quality across the full 12-inch jointing width
- Parallelogram table system maintains precise table alignment while allowing fast, accurate depth-of-cut adjustments
- Large 12-inch by 84-inch precision-ground cast iron table provides stable support for long and heavy workpieces
- Center-mounted cast iron fence uses rack-and-pinion adjustment for smooth movement and accurate positioning
- Fence preset stops allow repeatable setup at common angles, including 45 degrees in and out and 90 degrees
- Cast iron table lips on both sides of the cutterhead help dampen sound during jointing operations
- Heavy cast iron construction improves rigidity and vibration control for consistent jointing results
- Recommended maximum cutting depth of 1/8 inch for jointing and 1/2 inch for rabbeting supports controlled material removal
