Adapter, 3" Spindle to 5" Lathe Chuck - 95MM Registration

Adapter, 3" Spindle to 5" Lathe Chuck - 95MM Registration - Main image
$18.57 $29.95 In stock

5" Lathe chuck adapter.

This adapter lets you mount a 5" lathe chuck on your mini lathe in place of a 3" (80 mm) chuck.

The adapter mounts to the 3-hole pattern on the spindle so it works on spindles with only three holes.

This adapter has a 95 mm diameter registration boss and is drilled for both 3- and 4-jaw chucks on a 108 mm bolt circle.

* Note Don't forget to purchase the appropriate set of Studs & Nuts to accommodate changes in chuck or adapter configurations.

Customer Reviews (4.8 / 5 · 5 reviews)

Ava X. ★★★★★

The registration ring fits snugly without any wobble, and swapping between my 3" and 5" chucks takes under a minute now.

Scarlett E. ★★★★★

Installed this on my mini lathe and the 3-hole pattern lined up perfectly—no fiddling required. Makes swapping to a larger chuck really simple for bigger projects.

Emma F. ★★★★★

The machining on the adapter is clean and the 95mm registration seated perfectly against my spindle face, so there was zero wobble when I mounted the 5" chuck. Took me about ten minutes to swap everything over, and now I can finally use my bigger chuck for bowl work.
