Adattatore, Mandrino tornio 5", Tornio da banco HiTorque 9x20

Exactly the right fit for my 9x20 lathe spindle, and the threads were cleanly cut with no burrs. It mounted up solidly without any wobble. Just note that you'll need to order the three studs separately if you don't have them.

Took a chance on this adapter since I needed to mount a 5" chuck on my 9x20, and the machining is spot-on—threads on cleanly and the plate seats flat with zero wobble. Just remember you’ll need three studs separately if your spindle lock isn’t already set up, but once that’s done it’s rock solid.

The holes lined up with my spindle threads without any filing or fuss, which was a relief. I just wish the listing had been clearer about needing the three studs separately, but once I had those, it was a solid mount.
