夾頭轉接器，1"-8牙 5吋直徑

The 5" diameter fits my chuck perfectly, and the 1"-8 thread spun on smooth with no wobble. Cast iron feels dense enough that I'm not worried about vibration at higher speeds, and since there are no pre-drilled holes, I can mark and drill exactly where my chuck needs them.

Threaded onto my 1"-8 spindle without any wobble, and the cast iron feels solid enough to handle my heaviest 5" chuck. The lack of pre-drilled holes meant a quick drilling session, but that’s exactly what I needed for a custom fit.

The 5-inch diameter is a perfect match for my lathe’s spindle, and the cast iron feels solid enough to handle steady work without any wobble. Screwed on cleanly and sits flush, so my chuck mounts up true.
