Dynabrade Dynorbital-Spirit 5-inch Random Orbital Sander, 3/16-inch Orbit, 12,000 RPM | Non-Vacuum

Meet the Dynabrade Dynorbital-Spirit 5-inch Random Orbital Sander, a non-vacuum model designed for professionals who value precise surface preparation and consistent finishing. The 5-inch sanding pad pairs with a 3/16-inch orbit to deliver a swirl-free finish on a wide range of materials, from raw wood to painted or coated surfaces. The tool is powered by a compact 0.25 hp pneumatic motor that reaches up to 12,000 RPM, providing smooth, controllable power where you need it most.

In the hand, the sander feels balanced and purposeful. The recessed throttle lever gives thumb-controlled speed adjustments that help reduce fatigue on the palm during extended sessions, while a precision, one-piece motor shaft and counterbalance work together to minimize vibration and keep surfaces stable. The integrated muffling reduces exhaust noise without compromising airflow, enabling more comfortable operation in busy workshops.

Performance you can rely on

The Dynorbital-Spirit uses a floating five-blade rotor to extract more usable power from the air you supply, and a high-strength composite design that stands up to daily use. With an efficient air draw of 14 SCFM (396 LPM), you get steady performance without wasting compressor capacity. For projects that require dust management, this sander can be paired with Dynabrade’s self-generated or central vacuum conversion kits, offering flexibility to fit your shop configuration.
