Abigail ★★★★★

Finally swapped my adapter to this one—the brass threading is much smoother than the steel I was using before. Secured tightly on the first try with no wobble. Exactly what I needed for the new sander.

Natalie ★★★★★

Perfect fit for my orbital sander setup, and the threads engaged smoothly without any wobble. I grabbed the two-pack so I can keep a spare on the bench.

Lucy ★★★★★

Needed this to connect my sander and it threaded on perfectly without any wobble. The two-pack option was nice since I have multiple tools to hook up.
