L-3 Quick-release cartridge assembly
Allows for the fast change-over of cutter guide bushes.
The quick-release cartridge assembly allows for the fast change-over of cutter guide bushes. With two catridges you can also utilise cutter guides of differing outer diameters.
By using the catridge assembly to change guide bushes, you can do the job away from the cutting machine, thus avoiding any risk from the knife blade.
