Heavy Duty 1 2 Inch Arbor Adapter For Polishing And Buffing
✔️ Extends motor spindle to 2 1/4inch thread mount for solid wheel

This shaft adapter converts a standard half inch motor spindle into a threaded mounting hub. You will use it to attach polishing pads, wire brushes, and buffing wheels safely. The longer screw mount gives you more room to tighten heavy duty wheels without hitting your guard. It works well for bench grinders, drill motors, and small workshop tools.

✅ Slides onto matching half inch spindle and locks with set screw.
✅ Adds four extra teeth of threading to keep heavy wheels from wobbling.
✅ Ships with hex wrench and two thin washers for quick setup.
✅ Finished in silver steel that handles high speed friction.

- Longer screw length provides deeper nut seating and reduces vibration drift
- Correct pitch alignment matches common motor threads for fast swapping
- Steel body withstands continuous heat cycles without warping under load
- Direct slide fit allows quick upgrades to existing bench machines
