Common Knife Blades Used For Summa Cutting Systems | Digital Cutter | Flatbed Cutter For Sale Shop

Types of Summa Knife Blades

1. Drag Knife Blades

· These blades swivel around corners while staying in contact with the material, suitable for general-purpose cutting.

· Common angles include:

o Standard 36° Blade: Ideal for cutting normal to thin vinyls and masking films.

o Rhinestone 50° Blade: Used for more detailed cuts.

o Sandblast 60° Blade: Used for tougher materials, requires a special holder.

· Drag blades fit in standard holders like Summa 391-332 or special holders depending on the blade type.

2. Tangential Knife Blades

· These blades lift and rotate for precise orientation, providing higher cutting accuracy.

· Common blade angles:

o 36° Standard Tangential Blade (Summa 390-534): Suitable for soft materials like vinyl, magnetic foil, and polyester fabric up to 0.25 mm thick.

o Double Edge 36° Blade

o Double Wedge 45° Blade

o Sandblast 60° Blade: For cutting thicker and tougher materials such as sheets, banners, and polyester fabrics up to 1.20 mm thick.

· Tangential blades are used in Summa's tangential modules and holders.

3. Specialty Blades

· 35° Vinyl Cutter Blade: Made from 13% cobalt ultra-fine grain carbide, designed for delicate, thin films/media (1-2 mil thick), compatible with Summa D-Series cutters.

· Oscillating Knife Blades: Used for intricate details and cutting thick materials like foam and rubber; blades such as Summa 500-9810, Summa 500-9807 are examples designed for oscillate cutting with minimal overcut and robust tips.

· Other blades include V-Cut blades, perforation blades, kiss-cut blades, and creasing tools, often used in flatbed cutting systems for specific applications like angled cuts, tear-off lines, or scoring.

Blade Materials and Features

· Carbide Blades: Extremely durable, suitable for tough materials.

· Steel Blades: More affordable but wear out faster.

· Coated Blades: Some blades have coatings like titanium to extend life and reduce friction.

Blade Selection Considerations

· Choose the blade angle based on material thickness and type:

o Lower angles (30°-45°) for thin, delicate materials.

o Higher angles (60°+) for thicker, tougher materials.

· Ensure blade compatibility with your Summa cutter model and holder type.

· Adjust cutting force and offset settings when changing blade angles to maintain cut quality.
