The Powermatic OES9138B-3 9" × 138" Oscillating Edge Sander, powered by 230V three-phase, is built for production environments requiring continuous-duty sanding and consistent performance.

The Powermatic OES9138B Oscillating Edge Sander is engineered for accurate edge sanding, consistent surface finishes, and efficient material removal across a wide range of woodworking applications. Its 9" × 138" abrasive belt provides ample surface area for large panels, curved workpieces, and long stock.

An oscillating belt system operating at 30 to 50 oscillations per minute helps keep abrasives cleaner, reduces heat buildup, and extends belt life. Variable belt speeds from 1000 to 4200 FPM allow operators to fine-tune performance based on material type and finish requirements.

A large stay-flat work table provides stable support for precise sanding, while the adjustable belt tilt (0–45°) enables accurate angle and edge sanding. The strategically placed 4-inch dust port improves dust extraction efficiency, keeping the workspace cleaner during extended use.

Operator convenience is enhanced through easily accessible controls and a clear display, supporting quick adjustments and intuitive operation. Smooth-moving handles and durable construction reflect Powermatic’s focus on long-term reliability in professional shops.

Like all Powermatic machines, the OES9138B is backed by a 5-year warranty, reinforcing confidence in its craftsmanship and performance.
