works great

It works! The only downfall was it didn’t come with the Allen wrench for the screw like it said it would, so we had to improvise.

Out with the old

This arbor seems nicer then the original that came with the machine. A little beefier and works great

It is what it is

Had a bit of a struggle getting the new arbor on (100% our own fault, as the old arbor had bonded to the old motor). Once the old arbor was off, super easy process.

Whole process was nice and easy, great customer service, quick shipping, never been disappointed with Hi-Tech

Much-needed spare part

The arbor that came with my original All-U-Need machine was clearly worn out, causing my grinding discs and polishing pads to wobble and make noise. My new arbor has corrected that problem completely, restoring smooth grinding and polishing operation.
