The CWT/CWX E12A is a double edged flat stock drag knife blade designed specifically for Colex Sharpcut flatbed cutters and compatible digital cutting systems. This blade shares the same geometry as the E12 but features a shorter shank length to ensure compatibility with certain table manufacturers.
With two cutting tips, the E12A delivers extended usable life compared to single edge blades, allowing operators to rotate the blade and continue production without immediate replacement. The blade offers a larger overcut and longer cutting life compared to the E13 series.
Featuring a 50 degree cutting angle and compact 4.8 mm cut length, the E12A is engineered for universal cutting applications across rigid plastics, flexible films, carton board, and composite materials used in signage, packaging, and industrial digital finishing.
This configuration is particularly suited for Colex Sharpcut platforms requiring the shorter shank design.
