The three pre-drilled holes made mounting this to my lathe faceplate quick and straightforward. I had to do a bit of cleanup turning to get a perfect fit on my 4-inch chuck, but everything mates up nicely now. Solid piece of steel for the price.

I’ve been using this 4-inch adapter with a 3-jaw chuck on my mini lathe, and the pre-drilled 3-hole pattern saved me a lot of setup time. The threads were clean and fit perfectly without any jiggle, so it feels sturdy during operation.
