What are the differences between the iECHO E74 and E13 blades

The main differences between the iECHO E74 and E13 blades are as follows:

iECHO E74C Blade

· Made of solid tungsten carbide with extreme durability.

· Designed as a very fine, delicate drag blade with minimal overcut, optimized for cutting small radii and intricate details.

· Maximum cutting depth is about 20mm.

· Typical applications include foam board, ABS plastic, plastic corrugated board, corrugated paper, cardboard, grey cardboard, carpet, seal ring, carbon fiber prepreg, and similar materials.

· Blade dimensions: approximately 52mm height, 46mm width, 1mm thickness, with a 45° cutting angle.

· Classified as a drag blade, flat, V-cut type.

iECHO E13 Blade

· Also made of tungsten carbide but with different dimensions.

· Blade size: length 50mm, width 8mm, thickness 1.5mm.

· Designed for general cutting tasks but with a thicker blade compared to E74.

· Suitable for similar materials but likely less specialized for very fine, intricate cuts due to larger thickness.

· Classified as a tungsten steel blade, drag blade type.

Summary of Differences

In essence, the E74C blade is thinner, finer, and optimized for detailed, precise cutting with minimal overcut and a decent cutting depth, while the E13 blade is thicker and likely more robust for general cutting tasks but less specialized for fine detail work.
