The blocks and do-grip adapters from Iscar are designed for cut-off machines and they are composed of Manchester tools enabling them to be mounted on the Manchester block.
These tools lessens the consumption of time for insert and adapter as they are easy to use. Moreover, they allow the direct replacement of adapter on the machine in times when the Manchester system works as a bottom support, an upper clamp and side clamping screws. However, this system needs block removal to alter the adapter which is single-ended compared to the Iscar's adapter which is double-ended.
The latter's adapter, can also be mounted on a Manchester block but the catch is, the manchester's block can not be mounted on Iscar's adapter.
