Key Technical Specifications

Cutting Angle: 55° to 60° (designed optimized for maximum penetration in thick or dense layers).
Shank Diameter: 2.0 mm (standard vinyl drag blades typically use a thinner 1.5 mm shank).
Blade Offset: 0.25 mm to 0.5 mm (depending on exact factory variant or aftermarket customization).
Maximum Cutting Thickness: Approximately 0.03" / 0.8 mm.

Compatibility & Hardware Requirements

Machine Compatibility: Designed for use with Summa D-Series (Drag Knife) plotters, including the SummaCut and S Class D-Series lines.
Special Holder Required: Because of the thick 2.0 mm shank, these blades will not fit into a standard 1.5 mm black drag knife holder. They must be paired with Summa's specialized copper/gold thick-material drag tool holder (Part Number: 391-363 or current 9TL89-67033 thick variant).

Recommended Applications

Sandblast Stencils: Ideal for cutting heavy rubber masking and sandblast-resistant films.
Thick Materials: Highly effective for magnetic sheeting, thick cardstock, and heavy-duty reflective vinyl.
Floor Graphics: Easily slices through thick, laminated floor vinyl substrates
