Meet the Diablo DS1214BF25: a 12" bi-metal reciprocating saw blade engineered for medium metal with speed, durability, and control you can feel on every cut. Designed for material ranging from 1/16" to 5/16" thick, this 25-pack delivers professional performance straight to your toolbox.

Why these blades stand out

• Full Contact Arched Design with an ultra-hardened cutting edge powers through metal faster, reducing the number of passes and minimizing heat buildup for cooler, cleaner cuts.
• Up to 5x longer cutting life versus standard bi-metal blades, so you can tackle more jobs between blade changes and maximize productivity on the job site.
• Dual-tooth configuration with small gullets accelerates material removal while preserving durability, helping you cut through metal more efficiently.
• Oversized blade body stabilizes the blade to reduce chatter and vibration during crucial cuts, improving accuracy and comfort.
• Perma-SHIELD non-stick coating minimizes heat buildup, prevents gumming, and resists corrosion, keeping blades working smoothly longer.

What you get and who it’s for

• One 25-pack of DS1214BF25 blades, ready for heavy metal applications across multiple trades.
• Ideal for professional remodelers, metal fabricators, electricians, plumbers, and HVAC technicians who cut conduit, structural metal, or sheet metal in varied thicknesses.
• Perfect for tasks where clean, fast cuts matter most—think mounting plates, channel work, or cutting through mild steel and similar metals.

Use cases and practical benefits

• the Full Contact Arched Design & dual-tooth geometry mean you reach target dimensions quicker, reducing wear on your saw and machine downtime.
• cooler cuts minimize warping and material fatigue, yielding straighter, more precise results.
• Less tool chatter: the oversized blade body steadies the blade in challenging cuts, especially when cutting long channels or mounting holes.
• Long-term reliability: the combination of heat-resistant coating and hardened edge translates to sustained performance across repeated jobs.

Choosing the right blade and tips for best results

• Use the 14/18 TPI configuration for medium metal: balanced speed and smoothness for typical metal cutting tasks.
• Keep blades sharp and clean; the Perma-SHIELD coating helps resist gum buildup and heat, but periodic cleanup extends life.
• Secure workpieces and avoid forcing the blade; let the blade do the work to prevent premature dulling or bending.

With the Diablo DS1214BF25, you’re equipped for efficient, reliable metal cutting across a range of common job-site scenarios. Its focused design and durable build set it apart from typical bi-metal blades, delivering faster cuts, cooler operation, and longer life—so you can finish more work with fewer blade changes.
