391-360 - Summa 36° rotating cutting blade – diameter 1.5 mm

Summa 36° Drag Knife — Ref. 391-360

The 391-360 blade is Summa’s original 36° standard rotating (drag) knife blade, made from tungsten carbide. With its 36° cutting angle, it is optimised for the precise cutting of thin to standard vinyls and masking films, including small text and fine details. Its 0.45 mm offset geometry ensures precise path tracking at every change of direction.

The tungsten carbide blade offers a service life 10 to 50 times longer than a standard steel blade, reducing the frequency of replacement and ensuring consistent cutting quality over time. It is used with the standard Summa blade holder ref. 391-332 (now 9TL89-67033). This part number 391-360 is replaced by the new part number 9TL89-67041.
