Mudder 45mm Rotary Cutter Replacement Blades — 36-Pack Refill, Alloy-Steel, Rust-Protected Case

Mudder 45 mm 36 Packs Rotary Cutter Replacement Blades are a bulk set of 45mm alloy-steel circular blades designed to replace worn rotary cutter wheels for fabric, vinyl, and craft projects.

Whether you sew, quilt, upholster, or craft, keeping fresh, sharp blades on hand speeds cutting and keeps edges clean. This Mudder pack supplies 36 individual 45 mm blades plus a clear storage case, offering a convenient refill option for most standard rotary cutters and handle styles. The blades are machine-oiled for rust protection and sized to fit many mechanical and ratcheting handles.

How sharp are these blades and what materials will they cut?

The blades are stamped from alloy steel and finished with pointed cutting teeth to slice through layers without dragging. They handle multiple soft-to-medium density materials and keep a clean edge over repeated passes.

• Cuts up to six fabric layers in one pass for quilting and sewing.
• Suitable for cotton, denim, felt, fleece, vinyl, leather, wallpaper, and cardboard.
• Not recommended for very hard or abrasive materials like glass or metal.

Will these blades fit my rotary cutter handle?

These 45 mm blades are made to be widely compatible and will fit most common rotary cutter models that accept 45 mm wheels. They work with both simple and mechanical/hob-style handles when the cutter’s mounting hardware accommodates a 45 mm wheel.

• Standard 45 mm diameter fits most household and craft rotary cutters.
• Use original cutter screws and washers when replacing the blade for safe installation.
• If unsure, measure your current blade or consult your cutter’s manual before purchase.

How long do the blades last and how should I store them?

Longevity varies by material and frequency of use; blades dulled by abrasive fabrics will need more frequent replacement. The Mudder set arrives machine-oiled to resist rust and includes a clear plastic box that helps keep blades organized and protected between uses.

• Replace blades at the first sign of pulling, fraying, or rough cuts for best results.
• Keep unused blades in the provided storage case to prevent damage and moisture exposure.
• Dispose of used blades safely in a blade bank or taped container to avoid injury.

Who is this for: This 36-pack is aimed at home sewists, quilting enthusiasts, small craft studios, costume makers, and anyone who prefers to keep multiple fresh blades on hand to maintain precise, efficient cutting. It’s particularly useful for people who work on layered projects or switch frequently between materials and need a cost-effective way to restock blades without searching for singular replacements.
