Michael ★★★★★

The 95 mm recess on this adapter matched my chuck perfectly, so no wobble during turning. I appreciate that the 72 mm boss fits snugly on my lathe spindle, making setup quick and easy.

Avery ★★★★★

Took a gamble on the 72 mm boss lining up with my 8x14 lathe's flange, and it seated perfectly with zero wobble. The six holes aligned without any filing, so the chuck went on in under five minutes.

Sofia ★★★★★

Finally found an adapter that actually fits the 95mm registration recess on my chuck without any wobble. The 6-hole pattern lined up perfectly with my 8x14 lathe.
