Diablo Reciprocating Saw Blades DS1214WBF25 9 Inch Steel Demon Bi-Metal (20/24 TPI Dual Tooth Perma-Shield Coating Thin Metal Demolition 25-Pack)

Slice Thin-Walled Tubing and Sheet Metals Burr-Free with 20/24 TPI Dual-Tooth Demolition Blades
The Diablo DS1214WBF25 9-inch bi-metal reciprocating saw blade set delivers industrial-grade material sectioning and precise straight cuts for HVAC ducting, commercial plumbing, and high-volume thin metal demolition. Engineered with an ultra-hardened HRC 62 matrix cutting edge, these 20/24 TPI dual-tooth blades feature a double tooth design with small gullets to accelerate waste evacuation while preventing tooth stripping on dense metals. The 9-inch extended length and 1-inch oversized demolition body height minimize lateral blade deflection and chatter inside tight wall cavities, utilizing a permanent Perma-SHIELD non-stick formulation to shield the core from dynamic friction drag, heat buildup, and jobsite corrosion.

Best Used For:

• Thin-Walled Metal Tubing: Slicing straight, clean cuts through commercial plumbing conduits, structural copper lines, and electrical metal tubing (EMT).
• HVAC Sheet Metal Demolition: Cutting apart large diameter ventilation profiles, galvanized ductwork layouts, and furnace steel housings.
• Wall Cavity Mechanical Adjustments: Reaching deep into finished wall spaces to plunge-cut through thin structural steel frames or alloy pipes without walking.

Key Performance & Safety Features

• Dual Tooth Configuration: Double tooth profiling paired with compact gullets accelerates material clearing speeds and maximizes tooth durability.
• HRC 62 Ultra-Hardened Edge: Premium heat-treated steel edge delivers extreme hardness to outlast standard competitor blades by up to 5X.
• 1-Inch Oversized Demolition Body: Tall blade plate design secures absolute tracking rigidity to enforce straight linear cuts and suppress structural chatter.
• Perma-SHIELD Heat Armor: Proprietary non-stick protective coating lowers machine drag to prevent pitch accumulation and prevent raw steel rust.
• Specialized Rapid Plunge Tip: Pointed entry geometry bites directly on contact to streamline quick plunging maneuvers into dense metal surfaces.

Pro-Tip: When cutting thin, vibration-prone metal ducts or sheet stock, ensure your saw's pivoting shoe rests firmly against the material surface. Keeping solid structural contact dampens harmonic blade chatter and enables the high-density 20/24 TPI dual tooth arrays to perform clean, burr-free linear sweeps.
