Irwin 25831637 Reciprocating Saw Blade 9 Inches 6 Tpi

Product Description

The IRWIN 25831637 is a 9-inch, 6 TPI bi-metal reciprocating saw blade engineered for roughing-in work and nail-embedded wood cutting. Built with an electronic beam weld, the teeth bond is stronger and longer-lasting than conventional welding methods. The blade incorporates 8% cobalt into the tooth composition, which extends edge retention and keeps teeth sharper through demanding cuts. Precision-set teeth reduce friction and improve cut smoothness. This blade is rated for use with materials 3/16 inches thick and thicker, making it a go-to choice for demo and rough carpentry applications where embedded fasteners are expected.

This blade is suited for residential and light commercial applications where reciprocating saws are used for demolition, rough framing, and remodeling work. Typical scenarios include cutting through dimensional lumber, engineered wood, and salvaged framing members that contain nails or staples. The bi-metal construction allows it to contact embedded fasteners without catastrophic tooth loss, which makes it appropriate for teardown and renovation work where material composition is unknown or inconsistent.

Key Features

• Electronic beam weld for stronger tooth-to-body bond and extended blade life
• 8% cobalt tooth alloy maintains edge sharpness through nail-embedded and abrasive wood cuts
• Bi-metal construction resists tooth breakage on contact with embedded fasteners
• Precision-set teeth for faster, smoother cutting action
• Rated for materials 3/16 inches thick and thicker
• 9-inch length with 6 TPI geometry suited for aggressive, high-material-removal cuts

Compatibility

Designed as an OEM-style replacement blade for use with standard reciprocating saws accepting universal shank blade mounts.

Installation Notes

Installation is performed by electricians, carpenters, plumbers, and general contractors using standard reciprocating saws. Always power down and disconnect the saw from its power source before changing blades. Wear appropriate PPE including eye protection and cut-resistant gloves when handling used blades or cutting nail-embedded material. Inspect the blade before each use and replace if teeth are stripped, bent, or cracked.
