Customer Reviews (4.4 / 5 · 5 reviews)

Ava V. ★★★★★

Had to swap out the original arbor on my bench grinder and this one threaded on smooth with no wobble. The right-turn direction matched my setup perfectly and it holds the wheel firmly at speed.

Harper R. ★★★★★

Fits perfectly on my grinder with the 1/2"-20 female threading, and the right-turn direction was exactly what I needed. Machining is solid—no wobble when I spun it up, it seated flush without any fuss.

Samuel M. ★★★★☆

Fit tight on the arbor shaft of my buffer, no wobble at all. The right-hand thread direction matches what I needed for standard rotary work. Only wish the steel felt a tiny bit more substantial for heavy load use.
