CMT JT313AW-3 Jig Saw Blades for Soft Materials are high-carbon steel knife-edge blades engineered specifically for slicing through soft, flexible, and compressible materials - not tearing through them. Sold as a 3-piece pack, these 6-inch HCS blades feature a sharp knife edge (no teeth) that cuts cleanly through cardboard, polystyrene, carpet, leather, rubber, and fiberglass thermal insulation panels up to 4 inches thick. The universal T-Shank design fits all major jig saws and cordless jig saws, making these blades a ready-to-use solution for insulation cutting, packaging work, upholstery cutting, and other soft-material fabrication tasks.

Key Features

• Sharp Knife-Edge Blade (No Teeth) - slices cleanly through soft, fibrous, and compressible materials without tearing, crushing, or jamming the way toothed blades do, delivering smooth, controlled cuts every time.
• High-Carbon Steel (HCS) Construction - provides the flexibility and durability needed for repetitive cuts through soft materials like carpet, rubber, and insulation, reducing blade fatigue during extended use.
• Universal T-Shank - fits all major jig saws and cordless jig saws with no adapter required, so you can mount and start cutting without additional hardware or compatibility concerns.
• Up to 4-Inch Cutting Capacity - handles thick insulation panels and other bulky soft materials in a single pass, eliminating the need for multiple scoring passes or repositioning.
• 3-Piece Pack - multiple blades included so you have replacements ready for ongoing projects, reducing downtime when cutting abrasive or dirty soft materials like carpet or rubber that can accelerate wear.
• 5-59/64 Inch Total Blade Length - a generous blade length that maintains reach and control when cutting through thick or layered soft materials.

Why This Product

• Standard toothed jig saw blades tear, compress, or jam when used on soft materials - this knife-edge HCS blade is purpose-built for cardboard, polystyrene, carpet, leather, rubber, and fiberglass insulation panels, giving you a clean cut that toothed blades simply cannot produce.
• With a 4-inch maximum cutting depth, these blades handle full-thickness fiberglass thermal insulation panels in a single pass - a practical advantage for insulation installers and contractors cutting panels to fit.
• The universal T-Shank eliminates compatibility guesswork - these blades are ready to use on virtually any jig saw or cordless jig saw without adapters or workarounds.
• Buying a 3-piece pack means you always have a fresh blade available, which matters when cutting materials like carpet or rubber that can dull or soil a blade faster than hard materials.
