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

Powermatic® 20-Inch Helical Cutterhead Planer, 5 HP, 1PH, 230V (209BHH) SKU: PM1-478 Overview 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. Features: Surface full-width panels - 20" × 8" capacity 68-insert helical. Consistent production finish Built-in DRO. Exact thickness, every operator 5 HP surfaces wide, dense stock without slowing Four-row helical cutterhead with carbide inserts delivers a smoother finish, operates more quietly, and outlasts straight-knife heads with individual insert rotation for fast, low-cost maintenance Built-in digital readout displays exact board thickness in real time, enabling precise, repeatable settings that hold across operators and multiple passes without re-measuring Solid cast iron infeed and outfeed tables resist flex and damp vibration, keeping long boards supported and the cutting surface consistent from end to end Selectable 16 and 28 FPM feed rates let operators choose between a refined finish pass and aggressive stock removal without any tooling changes 4-inch bi-directional dust port connects from either side for flexible placement in the shop Upgraded caster locking and braking system provides rolling mobility for repositioning while securing the machine firmly in place during cuts Enlarged, high-visibility emergency stop is positioned for immediate access, reducing operator response time and improving overall shop safety Specifications Type of Cutterhead Helical Head Knife Size (L x W x T) 0.59 in. x 0.59 in. x 0.10 in.
