5-inch pneumatic wheel for sanders

This 5-inch pneumatic wheel fits Dynabrade sanders that use a 5/8 inch -11 threaded connector. The rubber wheel with composite hub is designed for inflatable operation and accepts unslotted expanding material. It is built for professional finishing work where a compliant contact surface is required.

3500 RPM maximum speed and 3.5-inch width

The wheel is rated for a maximum operating speed of 3500 RPM, providing a safe ceiling for high-speed sanding tasks. Its 3.5-inch overall width gives a broad contact patch for consistent material removal on flat or contoured panels. Exceeding the rated speed risks wheel failure and operator injury.

Threaded 5/8 inch -11 mounting and rubber expander

A 5/8 inch -11 threaded hole allows direct attachment to compatible sander arbors without adapters. The unslotted expanding design grips abrasive sleeves securely once inflated, reducing slippage during use. The rubber wheel and composite hub resist corrosion and absorb vibration for smoother finishes.

Questions about this item

Will the 94472 pneumatic wheel fit the 13F631 sander I already own?

Yes, the wheel is listed specifically for the 13F631 model and uses a 5/8 in.-11 threaded hole connector that matches that sander.

How can I verify the 94472 wheel is running at the correct 3,500 RPM after installation?

Check the sander's speed setting or tachometer to confirm it does not exceed 3,500 RPM, the wheel's maximum operating speed.

Does the 94472 come with the 5/8 in.-11 mounting hardware or must I buy it separately?

The wheel includes a 5/8 in.-11 threaded hole for direct mounting; no separate connector hardware is required.
