Industrial 3-Knife Trimmer Blades Carbide for Books & Magazines
Detailed Description
Shen Gong’s carbide-tipped 3-knife trimmer blades are engineered to outlast standard steel blades by 3X. Designed for high-volume trimming of books, brochures, and magazines, these blades feature:
Tungsten carbide edges – Harder than steel, resistant to wear, and maintains sharpness longer.
Easy-swap design – Change blades in minutes, not hours (no specialized tools needed).
OEM flexibility – Send us your specs; we’ll match them exactly.
ISO 9001 backed – Consistent quality for industrial workloads.
Fun fact: Our blades are so tough, they’ve been spotted cutting through cardboard stacks like warm butter.
FEATURES
Extreme Hardness Performance
With 90+ HRA hardness (tungsten carbide), our blades outcut steel blades 3X longer, even when slicing dense paper stacks or glossy magazines.
Zero Micro-Cutting Edge
Proprietary carbide grain structure prevents edge fractures during high-volume trimming—no more wasted prints from ragged cuts.
Easy -Safe Replacement
Precision-engineered to fit Polar, Heidelberg, and hydraulic guillotine cutters—installs faster than a coffee break.
Customization as Standard
Need a non-standard size? Laser-etched part numbers? Send your specs. We’ll grind it to match, no MOQ hassles.
ISO-Certified Durability
Every blade is batch-tested to ISO 9001 standards because "maybe it’ll work" isn’t in our vocabulary.
