Diablo Reciprocating Saw Blades DS1214WBF25 12 Inch Bi-Metal (14/18 TPI Dual Tooth Perma-Shield Coating Auto Dismantling Metal Cutting 25-Pack)

Slice Hardened Vehicle Frames and Structural Alloys with 14/18 TPI Dual-Tooth Demolition Blades
The Diablo DS1214WBF25 12-inch bi-metal reciprocating saw blade set delivers industrial-grade material sectioning and aggressive straight cuts for automotive recycling, structural demolition, and metal recovery operations. Engineered with an ultra-hardened bi-metal matrix edge, these 14/18 TPI variable pitch blades feature a full contact arched design that increases active tooth engagement while reducing kinetic thermal fatigue. The oversized 1-inch thick demolition body minimizes vibration and blade whip inside restricted undercarriages, utilizing a specialized Perma-SHIELD non-stick formulation to shield the high-speed steel cutting paths from dynamic friction drag, gumming, and corrosion.

Best Used For:

• Automotive Vehicle Dismantling: Slicing straight through high-tensile passenger car pillars, hardened chassis frames, exhaust systems, and thick engine block mounts.
• Heavy Structural Metal Demolition: Sectioning heavy-wall structural pipes, steel rebar runs, angle iron framework, and rigid commercial mechanical tubing.
• Confined Space Recovery Work: Executing flush cuts along metal building frames, industrial piping layouts, and restrictive vehicle undercarriage components safely.

Key Performance & Safety Features

• Full Contact Arched Geometry: Structural curve design engages more teeth per stroke to accelerate metal clearing rates and maximize longevity up to 5X.
• Dual Tooth Configuration: Double-tooth profiling paired with optimized small gullets accelerates waste evacuation and resists tooth stripping on dense alloys.
• Perma-SHIELD Thermal Shielding: Proprietary anti-friction coating blocks structural heat buildup, preventing pitch adhesion and raw steel rusting.
• 1-Inch Oversized Demolition Body: Extra-thick heavy-duty backing plate provides premium rigidity to control tracking paths and prevent structural blade buckling.
• 14/18 TPI Variable Pitch Matrix: Universal tooth sizing manages variable substrate profiles cleanly, ranging from thin automotive sheet metal up to thick steel pipes.

Technical Specifications

Pro-Tip: When dismantling hardened steel auto pillars or vehicle frames, avoid using high-speed strokes. Operate your reciprocating saw at a moderate oscillation speed to allow the 14/18 TPI dual tooth geometries to bite cleanly into high-tensile alloys without frictional glazing, letting the 12-inch body layout displace processing heat naturally.
