DYNABRADE RB2 Air Polisher 3/8 in NPT Aluminum

Heavy-duty air polisher for professional finishing

The Dynabrade RB2 is a pneumatic rotary polisher built for heavy-duty surface preparation. Its fixed-speed motor delivers consistent cutting action on metal, composite or painted panels. The right-angle grip with side handle gives operators controlled leverage during extended polishing sessions. Shops that need repeatable results on large flat areas will find the tool matches the workflow.

Thermal load and air consumption at 90 psi

The motor draws 42 cfm at 90 psi while spinning at a fixed 2,800 rpm. Rear exhaust directs spent air away from the work surface and the operator’s hands. Because speed cannot be adjusted, the tool maintains a steady thermal profile without sudden load changes. A minimum 3/8 in supply hose keeps pressure drop low so the polisher sustains its rated horsepower throughout the job.

Integration with shop air systems and pad options

The 3/8 in NPT inlet threads directly into standard shop couplers using the specified hose size. An M14x2 spindle accepts the included 8 in hook-and-loop backing pad, which is also the minimum and maximum disc diameter. The 12 1/2 in overall length fits alongside other right-angle tools on a balanced manifold. Buyers who need variable speed or smaller pad diameters should select a different model.
