Summa T Series Tangential Cutter Plotter Knives Knife Blades

Summa T Series tangential cutter plotter knives, recognized by part numbers 390-534, 390-550, 390-551, and 390-560, are precision-crafted carbide blades tailored for use with Summa vinyl cutters and plotters. They are engineered to deliver sharp corners and highly accurate cuts on various materials, including vinyl, sandblast masks, and films, utilizing advanced motorized tangential cutting technology.

Blade Specifications
The distinguishing features of these blades lie in their cutting angle and tip design, which are optimized for handling specific material thicknesses and types effectively.

Part Number	Angle/Type	Max Thickness	Best For
390-534	36° standard (often 5-pack)	0.25 mm (10 mil)	Thin vinyls, masking films
390-550	60° standard	Varies by material	Thicker or tougher media like sandblast
390-551	36° double-tip	0.25 mm	Precision cuts, extended use
390-560	45° wedge (40°/25°)	Up to 0.25 mm	Large vinyls, varied films

Usage Tips
For thinner materials, lower angles around 36° are ideal to achieve cleaner edges, while steeper angles are better suited for cutting denser stocks. Constructed from tungsten carbide, these tools offer 10 to 50 times the lifespan of steel alternatives. They are compatible with Summa T Series holders, such as the 391-663 model. Opting for Shenzhen Oyea versions ensures seamless compatibility with S2 and S3 T Series plotters.
