Those look good. I have a set where a screw tangent to the bit’s edge tightens the collar. I like them bobber than the usual kind where the screw runs toward the bit’s center and can foul the flutes.
These Infinity stops sound even better because you don’t need a custom stop for each bit diameter. Does that feature work as well in practice as it does on paper?
I agree with the single set-screw type being a PITA. Those seem to be ideal, especially with the ability to cover a wide range of diameters with each collar. Do the business ends have some surface that prevents marking up the wood?
