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

391-360 – 36° drag knife (tungsten carbide) – Summa

The 391-360 is the standard genuine Summa 36° drag knife, in tungsten carbide. Its 36° cutting angle is optimised for precise cutting of thin-to-normal vinyls and masking films, including small characters and fine details.

Its 0.45 mm offset geometry ensures accurate path following at each change of direction. The tungsten carbide blade lasts 10 to 50 times longer than an ordinary steel blade, reducing replacement frequency and keeping consistent cut quality over time.

It is used with the standard Summa blade holder ref. 391-332 (now 9TL89-67033). This 391-360 reference is replaced by the new reference 9TL89-67041.

Function

• Standard rotating (drag) cutting of thin-to-normal vinyls and masking films
• Accurate path following thanks to the 0.45 mm offset
• Cuts small characters and fine details precisely
• Long life from the tungsten carbide edge

Signs of wear

• Incomplete or uneven cuts on vinyl
• Tearing or pull-out of the media while cutting
• Poor path following on small details or tight curves
• Cutting pressure abnormally high to get a correct result

Replacing this blade regularly keeps cut quality consistent and protects the media.
