the clamping kit is what I'd hoped it would be - they work great with my Grizzly Mill. Great kit for the money.

For the hobby machinist they are good. I did have to clean up the edges and retap a few t nuts. Overall good for the price.

Got these to make it easier to secure things on my drill press. Should have bought these years ago. Solved all sorts of frustrations, made it easy to secure larger items (2" thick steel disks) to the drill press.
