DeWalt DW4822B25 12-Inch 18 TPI Bi-Metal Reciprocating Saw Blades (25-Pack)
The DeWalt DW4822B25 12-Inch 18 TPI Bi-Metal Reciprocating Saw Blade 25-Pack cuts through heavy-gauge metal pipes, electrical conduits, structural steel angle iron, and thick metal studs. Engineered with a patented toothform configuration and high-speed Bi-Metal metallurgy, these 12-inch Sawzall blades deliver up to 50% longer operating life and optimized chip evacuation during intense demolition and industrial metal fabrication. Featuring an 18 Teeth Per Inch profile and a straight back design for maximum rigidity, this bulk contractor pack ensures professional tradespeople maintain fast, straight cuts through demanding metal assemblies without premature blade snapping.
Best Used For:
- Industrial Metal Pipe & Conduit Slicing: Cutting thick-walled steel pipes, threaded rods, and bundles of electrical conduit cleanly on plumbing and HVAC jobsites.
- Structural Angle Iron & Stud Demolition: Severing heavy steel angle iron, metal framing studs, and rebar during commercial structural tear-downs.
- Deep-Access High-Volume Fabrication: Utilizing the extended 12-inch length to reach into tight spaces and tackle large-scale production metal cutting.
Key Performance & Safety Features
- Up to 50% Longer Blade Life: Patented tooth geometry clears metal chips efficiently to reduce heat accumulation and extend cutting endurance.
- Flexible Bi-Metal Construction: Combines a hard high-speed steel cutting edge with a resilient carbon steel backing to absorb severe jobsite shock and prevent shattering.
- 18 TPI Fine Tooth Density: Optimized tooth pitch delivers smooth, professional finishes when cutting medium to heavy-gauge metals.
- Rigid Straight Back Profile: Straight edge design stabilizes the blade under high feed pressure for accurate, true-path straight cuts.
- Contractor Value 25-Pack: High-quantity bulk pack minimizes downtime and reduces per-cut operational expenses on commercial projects.
