The low profile of these clamps has been perfect. They hold the stock very well whether it's 3/4" wood or a 1.6mm PCB and they do not get in the way of the dust shoe.
Of course, no hold-down clamp is going to work for all CNC situations. These are excellent for providing a low-profile solid hold on a square edge a little over an inch in length and beyond five inches of extension beyond the material. They rise less and extend farther from the edge than Oops clamps. You must provide either a T-bolts for mounting in a T-track or some other type of threaded bolts for beds with threaded inserts. These connecting bolts are most likely metal which is the only part you need to worry about potentially damaging a bit.
I love these lever clamps. They are plastic so if I mess up and they get in a toolpath, it doesn’t damage the bit. I have used these for 3 years and would not use anything else. They hold great and give a low profile .
Love these clamps but my mistakes keep eating them. Wish I could purchase a digital file.
Great product. I use them all the time.
