Authorized Dealer Badge DEWALT logout

Cut Structural Steel Pipe and Heavy Conduit with Hardened Bi-Metal Resilience
The DEWALT DW4809B 8-inch 14 TPI bi-metal metal cutting reciprocating saw blade delivers professional-grade material breakdown and extreme impact resistance when tackling demanding industrial demolition. Engineered with an aggressive +5 degree hook angle, this high-performance blade maximizes chip removal speeds to ensure fast, efficient sectioning of heavy-gauge metals. The robust bi-metal body pairs a flexible, shatter-resistant spring steel backer with a hardened steel cutting edge to withstand intense high-tension forces, while its universal 1/2-inch shank locks securely into all major corded or cordless reciprocating saws.

Best Used For:

  • Electrical and Conduit Demolition: Sectioning thick-walled rigid steel conduit bundles, metal wiring trays, and mechanical electrical tracking.
  • Plumbing and Mechanical Piping: Slicing straight through structural steel pipe, gas lines, iron brackets, and heavy copper plumbing setups.
  • HVAC Structural Retrofitting: Ripping through heavy-gauge sheet metal ductwork, structural angle iron supports, and framing fasteners during demolition.

Key Performance & Safety Features

  • High-Speed Hook Angle: Aggressive +5 degree built-in angle configuration increases plunge speed and material penetration rates.
  • Bi-Metal Blade Matrix: Fusion of a flexible alloy steel backer with a premium hardened tooth edge guards against premature snapping.
  • Reinforced Tooth Profiles: Engineered heavy-duty tooth geometry withstands repeated impact forces from dense, high-hardness metals.
  • Anti-Vibration Raker System: Integrated raker tooth style absorbs tool chatter, dampening dynamic vibration for tracking accuracy.
  • Low-Friction Anti-Stick Coating: Specialty protective surface barrier prevents heat retention, pitch gumming, and oxidation.
  • Straight Back Body Profile: Broad straight-edge plate configuration provides rigid lateral support for perfectly square line cuts.

Pro-Tip: When executing aggressive cuts in thick structural steel pipe, keep the saw shoe pressed tight against the work piece. This controls long stroke lever forces and allows the reinforced 14 TPI bi-metal tooth pattern to clean the kerf efficiently, preventing tooth stripping from excessive blade bounce.
