The DongCheng HD110520 10-Piece 18mm Black Snap-Off Utility Knife Blade Set is an ultra-durable, professional replacement blade solution engineered for demanding cutting applications. Manufactured from high-tensile CK75 high-carbon alloy steel, each blade is crafted with an increased 0.6mm heavy-gauge thickness for superior rigidity and resistance against lateral deflection or breakage during forceful dragging cuts.

Featuring an advanced black oxide finish, these blades provide enhanced corrosion and rust resistance along with a low-friction surface that glides smoothly through sticky tapes, dense rubbers, and thick composites. The 12-segment design allows workers to break off worn tips to instantly access a razor-sharp edge. Sized at 0.6 x 18 x 100mm, they are packed in a secure plastic dispenser box of 10 blades.

Key Features

Extra-Thick 0.6mm Heavy-Duty Body: 20% thicker than standard blades, offering exceptional structural stiffness and resisting deflection in heavy materials.
Low-Friction Black Oxide Finish: Resists surface rust and reduces cutting drag through adhesive-backed materials and thick composites.
High-Tensile CK75 Carbon Steel: Provides razor sharpness and prolonged edge retention under severe construction loads.
12-Segment Precision Snap Design: Engineered with clean fracture points for fast edge renewal without jagged edges.
Universal 18mm Fitment: Seamlessly fits heavy-duty 18mm snap-off utility knives.
Protective Dispenser Box: Sturdy plastic dispenser ensures safe, single-blade dispensing on the jobsite.
