Blade Core Specifications:
This blade is designed for precision and compactness, making it ideal for fine machining of thin, hard materials. Constructed from solid carbide or tungsten carbide with a fine-grained HM composition, it ensures durability and superior performance. The blade features a single-edged drag cut with a 50° cutting angle (some brands may offer 45° or other slightly different angles depending on assembly requirements). Its maximum cutting depth is approximately 2.0 mm, with some models reaching 3.7 mm.
Blade dimensions include:
total length 14.5 mm, handle width 3.1 mm to 3.3 mm, and thickness 0.63 mm. With its sharp cutting angle and compact size, this blade is suitable for a variety of specific materials, minimizing drag and avoiding the risk of delamination or tearing. It excels at cutting cardboard or backing paper for picture frames and museum-grade framing. It also performs well in packaging solutions such as folding cartons, thin cardboard, and sample making. In the display and signage sector, it also excels in coated magnetic stickers and films, PC films, and precise half-cut pressure-sensitive labels.
