Professional Grade Metal Demolition Blade Set

The Diablo DS1208BFD25 12-Inch Bi-Metal Reciprocating Saw Blades are engineered for high-volume demolition in thick metal applications, featuring an ultra-hardened cutting edge for structural efficiency. With an 8/10 TPI dual-tooth design and HRC 62 edge hardness, these blades provide 5 times the operational life of standard bi-metal alternatives while facilitating rapid material removal. The 12-inch reach and thick demolition body minimize blade chatter, ensuring precise and straight cuts through high-tensile structural steel and thick-walled piping.

Best Used For:

  • Structural Steel Demolition: Rapidly clearing thick steel beams and support members during industrial teardowns.
  • Heavy Duty Pipe Recovery: Slicing through large-diameter pipes and industrial conduit with enhanced stability.
  • High Frequency Job Sites: Maintaining continuous site productivity with durable, long-reach blades designed for heavy-impact environments.

Key Performance & Safety Features

  • Dual Tooth Geometry: Double-tooth configuration maximizes chip clearance and structural durability for faster cutting speeds.
  • Ultra-Hardened Edge: HRC 62 hardness rating provides 5 times the operational life compared to standard HRC 55 blades.
  • Perma-SHIELD Coating: Industry-leading non-stick protection prevents heat buildup, gumming, and corrosion for cooler operation.
  • Oversized Body Profile: Extra-rigid blade height ensures straight-line accuracy and significantly reduced vibration during operation.
  • Universal Shank Interface: Designed to fit all major corded and cordless reciprocating saw brands for versatile site use.
