Replacement snap-off blades Irwin 18 mm, pack of 10, model 10504562

Replacement snap-off blades Irwin 18 mm, pack of 10, model 10504562 are spare cutting blades designed for utility knives and cutters that accept 18 mm snap-off segments. Each blade includes multiple break-off segments that restore a fresh cutting edge as segments are used and removed. The blades are intended for precise trimming, scoring and cutting of paper, cardboard, vinyl, drywall tape and other light sheet materials where a thin, sharp edge is required.

Advantages

These Irwin 18 mm snap-off blades provide consistent, sharp performance across multiple segments, reducing the need for frequent blade changes. The blades are manufactured to fit standard 18 mm holders, offering secure seating and reliable cutting alignment. A pack of 10 spare blades gives extended operating time and convenient on-hand replacement when working on repetitive cutting tasks.

• Scoring drywall tape and light gypsum board materials
• General workshop and craft cutting tasks

Key specifications

• Blade width: 18 mm
• Quantity: 10 blades per pack
• Type: snap-off segmented blade with multiple break-away sections
• Compatible with: utility knives and cutters accepting 18 mm snap-off blades

How to use

Insert a blade into the compatible utility knife according to the knife manufacturer’s instructions, ensuring the blade is securely seated and locked. Use the knife with steady, controlled strokes appropriate to the material being cut. When the active segment becomes dull, snap off the used segment along the scored break line to expose a fresh edge and continue cutting. Replace the blade entirely when all segments are consumed or if damage or excessive wear occurs.

Usage recommendations

For safe operation, always use a knife with a secure locking mechanism and a proper blade-breaking tool or the knife’s designated snap-off feature. Wear appropriate protective equipment such as cut-resistant gloves and eye protection when cutting dense materials. Store blades in a dry, secure place away from children and dispose of used segments according to local regulations for sharp objects.
