DF19 Shear, Crush, & Razor Cut Knife Holder

Product Details

DIENES DF19 shear knife holder provides zero-clearance vertical and horizontal stroke support for exceptional blade stiffness in operation. Slit widths to 19 mm (0.748 in) are possible. Originally developed for the aluminum foil industry, with a rigid flat blade, the DF19 also has a dish blade design for synthetic and other softer materials.

A simple Turn Knob release allows knife head changes with the knife body remaining on the machine.
