Utility Knife Blades Set Tajima DC560RB13D12 — 18 mm snap-off blades, auto-lock holder

The Tajima Utility Knife Blades Set DC560RB13D12 includes 18 mm snap-off steel blades and a compatible auto-lock holder designed for precise and repeatable cutting. The set provides segmented blades that allow rapid renewal by snapping off the worn tip, combined with an auto-locking knife body for stable blade fixation during use. It is intended for tasks requiring controlled, replaceable blades such as trimming paper, cardboard, vinyl, drywall and general workshop work.

Advantages

The 18 mm snap-off blades deliver consistent edge quality until the next segment is exposed, reducing downtime for sharpening. The auto-lock holder secures the blade firmly to minimise lateral movement, improving cutting accuracy and user control. Segmented blades are economical to maintain: only the worn segment is discarded, extending overall blade life. The components are made from hardened steel for durability in repeated cutting applications.

Suitable for

• Cutting paper and corrugated cardboard for packaging and crafts
• Trimming vinyl, carpet and wallpaper during installations
• Score-and-break operations on drywall and gypsum board
• General workshop and light construction cutting tasks

Key specifications

• Blade type: 18 mm segmented snap-off steel blades
• Holder: auto-locking utility knife body for secure fixation
• Blade renewal: snap-off segments for quick edge exposure
• Materials: hardened steel blades; metal/plastic knife body for durability
• Typical use: manual cutting of paper, cardboard, vinyl, drywall and similar materials

How to use

Insert a blade segment into the knife holder following the holder’s insertion guide until the auto-lock engages. Adjust blade extension to the required length for the material being cut and ensure the lock is engaged before applying force. Make controlled, forward cutting strokes using the knife edge; when the tip becomes dull, retract the blade, snap off the worn segment along the scored line using pliers or the knife’s built-in snapper, then advance the next segment and re-lock. Always keep fingers clear of the cutting edge and store the knife with the blade retracted.

Usage recommendations

Use appropriate cutting mats or sacrificial surfaces to protect underlying work areas and maintain blade sharpness. Wear cut-resistant gloves when working with tougher materials or when performing repetitive cuts. Replace blades when multiple segments are worn to maintain safe, efficient operation.
