I recently acquired a Hilma 125 vise that came with a pair of roller jaws that slip on the vise bottom and go between the regular jaws. The rollers exert a downward force due to the ramp on the back part of the jaw. They seem lightweight (the roller pivot is a 3 or 4 mm split pin), but I haven't tried using them. It appears that all the clamping force gets transmitted through the rollers, since they stand proud of the rest of the assembly, and even if they get forced down by the ramp on the backing part, the rest of the jaw doesn't clamp the work. The front part of the jaw is held in place only by a pair of shoulder screws in a slightly oversize bore, so it moves freely until it comes up agains the vise base.
Anyone else have one of these and can comment?
