4PCS Press Plate Clamp, CNC Arcuate Press Plate Clamp - T Track Hold Down Clamps Woodworking for CNC Milling Engraving Machine

Got these for my drill press and crossed my fingers as I don’t think they’re for that. Worked out great.

Well, I purchased these to use for my 3018 cnc machine. Since the original bolts didn't fit into the aluminum t-stot board, I swapped the bolts with 5/16-18" x 3" carriage bolts. The square part of the carrriage bolt fits perfectly into the opening of the t-slot board. I also wanted to be able to tighten these easier than the original thumb screws with some easy grip knobs. Overall a definate improvement from the originals which I needed to do to fit my machine. Yes, I could have returned these and bought different clamps that fit my machine but I do like the main clamping part of these and the way they're adjustable. I did have to spend more money to make these work for me but it was worth it.

Sturdy for the material used and easy to use. Bargain for the price.

this has 1/2 in bolt head.....i had to modify to work on table i bought

I bought these for my Delta drill press table. They probably work wonderfully for the intended CNC table application. But sadly, I had to grind the heads of the bolts to make this work. At some point I'll replace the bolts with imperial sizing just for consistency across the shop--I was just sad this wasn't identified in the write up (of course they'd be metric--didn't think).

Exelente

These are sturdy with hood range of adjustment.

Brother in law loved them for his woodshop.
