Powermatic PM1-478 20-Inch Helical Cutterhead Planer, 5 HP, 1PH, 230V (209BHH)

The Powermatic 209BHH is a 20-inch stationary thickness planer engineered for woodworking shops and cabinet operations that demand greater capacity and cutting power. Driven by a 5 HP, 230V, single-phase motor, the 209BHH (model PM1-478) processes wide panels and dense hardwoods with a 20-inch cutting width and an 8-inch maximum board thickness capacity — providing the ability to handle stock that a 15-inch class machine cannot. Its four-row helical cutterhead carries 68 four-sided carbide inserts spinning at 5,200 RPM, delivering a smooth, low-tearout surface finish with reduced operating noise and extended insert life compared to straight-knife configurations; inserts are individually accessible for rotation or replacement, reducing service time and keeping the machine productive. A built-in digital readout (DRO) ensures exact, repeatable thickness control, and two feed speeds — 16 FPM for fine finishing and 28 FPM for rapid stock removal — allow operators to optimize between surface quality and throughput. Solid cast iron infeed and outfeed tables provide a combined 51-1/2-inch table surface for stability and vibration damping when handling large workpieces. A 4-inch bi-directional dust port manages chip evacuation at a minimum 900 CFM, and the upgraded caster locking and braking system with oversized emergency stop reinforce safe, confident operation. The Powermatic 209BHH replaces the 209HH and is backed by a 5-year warranty.
