Experience Guaranteed Tough Metal Demolition with DEWALT Bi-Metal Speed and Durability

The DEWALT DW4809B 8-Inch 14 TPI Bi-Metal Reciprocating Saw Blade is engineered for professional-grade metal cutting and heavy-duty demolition. Designed with a focus on longevity and speed, this blade features a specialized +5 degree hook angle that provides aggressive, lightning-fast cuts in industrial materials. Whether you are slicing through rebar, thick-walled conduit, steel pipe, or structural angle iron, the bi-metal construction ensures a tough yet flexible blade body that resists snapping under high-tension use, making it an essential addition to any mechanical, electrical, or plumbing contractor’s toolkit.

Precision engineering is at the core of the DW4809B design. The reinforced tooth geometry provides exceptional durability, allowing the blade to maintain its sharp cutting edge significantly longer than standard carbon steel alternatives. To ensure maximum operator control and comfort, this blade utilizes a raker tooth design that effectively minimizes vibration and chatter during aggressive plunges. Finished with an industrial anti-stick coating to reduce friction and heat buildup, this straight-back blade delivers consistent, accurate results in the most demanding jobsite environments. Trust DEWALT’s "Guaranteed Tough" philosophy to keep your project moving with every stroke.

Key Features

  • High-Speed Hook Angle: A +5 degree aggressive hook angle facilitates faster material removal and increased cutting efficiency.
  • Bi-Metal Construction: Combines a flexible backer with hardened teeth for extreme durability and resistance to breakage.
  • Reinforced Teeth: Specially designed tooth geometry stands up to high-impact metal cutting for a longer service life.
  • Vibration Control: Integrated raker tooth design minimizes tool chatter, providing smoother, more accurate finishes.
  • Low-Friction Coating: Industrial anti-stick coating reduces heat buildup and gumming for a cooler cutting experience.
  • Straight Back Profile: Provides the stability needed for straight cuts in structural metal and heavy piping.

Pro-Tip: When cutting thick metal profiles like rebar or angle iron, keep your reciprocating saw at a steady, medium speed and avoid the orbital setting. Maintaining consistent pressure rather than forcing the blade allows the 14 TPI bi-metal teeth to score and slice effectively, preventing tooth fracture and extending the overall life of the blade's industrial anti-stick coating.
