Rigid, flat, vibration-free. Product Details The Powermatic 209BHH-3 is a 20-inch stationary thickness planer built specifically for woodworking production environments equipped with three-phase power. The 209BHH-3 (model PM1-479) is powered by a 5 HP, three-phase motor that ships 230V-wired from the factory and is field-convertible to 460V, making it compatible with a wide range of commercial and industrial electrical configurations. Its 20-inch cutting width and 8-inch maximum board thickness capacity enable high-throughput processing of wide panels and heavy stock. The four-row helical cutterhead carries 68 four-sided carbide inserts operating at 5,200 RPM, producing a consistent, professional surface finish with reduced noise and tearout; individual insert access allows fast rotation or replacement to minimize production downtime. An integrated digital readout (DRO) provides exact, repeatable thickness control, and two feed speeds, 16 FPM and 28 FPM, let operators balance finish quality and throughput based on material and schedule demands. Solid cast iron infeed and outfeed tables span a combined 51-1/2-inch surface, delivering the rigidity and vibration damping required for consistent results at production volumes. A 4-inch bi-directional dust port with a 900 CFM minimum requirement maintains effective chip management, and an oversized emergency stop with upgraded caster locking and braking system supports operator safety in high-use environments. Backed by Powermatic's Gold Glove Service and an industry-leading 5-year warranty, the 209BHH is built to earn trust long after it is in the shop. Features 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.
