Neeki Bench Grinder Shaft Extension for Polishing, 1/2" and 5/8" Motor Threaded Shaft Adapter, Fits 1/2" and 5/8" Center Hole Cloth and Airway Polishing Wheels

1. Just by installing this extension, you can easily convert the ordinary motor into a motor with polishing function, and the operation is very simple.

2. For more portable use, we designed 2 reducers for this extension. The first arbor reducer can achieve compatibility with 1/2" and 5/8" motor threaded spindles; the second arbor reducer can convert a 5/8" center hole cloth polishing wheel, airway polishing wheel, grinding wheel or wire brush wheel to a 1/2" hole to fit a 1/2" threaded shaft.

3. Widely used: After installing the extension shaft, the distance between the polishing wheel and the motor can be kept large enough to polish larger products. The distance between the two washers is up to 1 inch, which allows you to easily assemble polishing wheels of various thicknesses.

4. More secure: We designed 4 screw holes for the extension piece and equipped it with 4 machine screws, which can make the motor more secure when working. It is also equipped with a lock nut. After locking, the polishing wheel will not slip or loosen easily, even at high speed of the motor.

5. Our threaded shaft is a standard 1/2" thread, which fits better with the 1/2" polishing wheel.

Our bench grinder shaft arbor extension is suitable for 1/2" and 5/8" motor threaded shafts, and is also suitable for cloth polishing wheels or airway polishing wheels with 1/2" and 5/8" center holes. The arbor adapter of the extension shaft is 2.64" long, which can keep a large enough distance between the polishing wheel and the motor to polish larger products. The distance between the two flanges is up to 1 inch, which allows you to assemble polishing wheels of various thicknesses.
