Cutting tool JWIS

iwis tools are very handy for the workshop as they make it easy to cut roller chains made to ISO 606 (DIN 8187/8188) and to our works standard in different lengths. This chain breaker can be clamped in a vice or screwed onto a workbench. Position it at the front edge of the bench to provide enough space for the lever to swing down fully. Surfaces to rest the chain to the left and right will make it easier to handle long chains.
