محول ظرف، M39×4 سنون، قطر 6 بوصة

The M39x4 threads lined up perfectly on my 9x20 lathe spindle, and the solid 6-inch diameter gives me a nice stable platform. Having no pre-drilled holes was exactly what I needed so I could customize the bolt pattern for my specific 4-jaw chuck.

The threading matched my 9x20 lathe spindle perfectly, with no wobble at all. I appreciate that it's blank so I can drill the hole pattern exactly where I need it for my 4-jaw chuck.

This 6-inch diameter chuck adapter fit perfectly on my 9x20 lathe's spindle without any wobble. The clean finish left no burs, and it was easy to drill exactly where I needed for my 4-jaw chuck.
