Diablo 9" 14/18 TPI Bi-Metal Reciprocating Saw Blades for Medium Metal are precision-engineered cutting tools built to handle demanding metal cutting tasks with speed, durability, and control. Crafted with a Dual Tooth design and a variable 14/18 TPI configuration, these blades are optimized for cutting metal ranging from 1/16" to 5/16" thick - including rebar, angle iron, cast iron, and steel tube. Compatible with both corded reciprocating saws and cordless reciprocating saws, they deliver professional-grade results across a wide range of metal fabrication and demolition scenarios.

Key Features

• 9" Blade Length - provides extended reach into deep cuts and tight workspaces, reducing the need to reposition the saw during metal cutting tasks.
• 14/18 Variable TPI (Teeth Per Inch) - the dual tooth pitch alternates between 14 and 18 TPI to balance fast material removal with a smooth, controlled cut in medium metal applications.
• Dual Tooth Design - a double tooth configuration with small gullets accelerates chip evacuation and material removal while adding extra blade durability, meaning fewer blade changes on the job.
• Bi-Metal Construction - combines a flexible alloy steel body with a hardened high-speed steel cutting edge, so the blade resists breakage under stress while maintaining a sharp, aggressive cut.
• Full Contact Arched Design - maximizes the number of working teeth engaged in the material at once, resulting in faster cuts in fewer passes and reduced heat buildup for longer blade life.
• Perma-SHIELD Non-Stick Coating - protects the blade surface from heat, gumming, and corrosion, extending usable blade life and reducing friction during cuts through steel tube, cast iron, and similar materials.
• 1" Demolition Body - the oversized, ultra-rigid blade body minimizes lateral flex and vibration, delivering straighter cuts with greater control through rebar, angle iron, and structural metal.
• Compatible with Corded and Cordless Reciprocating Saws - the universal shank fits standard reciprocating saw tool systems, making it a versatile choice for both jobsite and shop use.

Why This Product

• Designed specifically for medium metal from 1/16" to 5/16" thick - including rebar, angle iron, cast iron, and steel tube - this blade eliminates the guesswork of choosing the right TPI for the material at hand.
• The combination of Full Contact Arched Design and Dual Tooth configuration means more teeth working at once and faster chip removal, translating to up to 5x longer cutting performance compared to standard bi-metal blades.
• Perma-SHIELD coating actively reduces heat buildup and corrosion on the blade body, which extends blade life and maintains consistent cutting performance across long work sessions in metal cutting applications.
• The 1" demolition body and arched blade geometry reduce vibration and blade wander, giving users straighter, more controlled cuts through structural metal with less physical fatigue over time.

Frequently Asked Questions

What types of metal can these Diablo bi-metal reciprocating saw blades cut?

These blades are designed for medium metal applications ranging from 1/16" to 5/16" in thickness. Specific compatible materials include rebar, angle iron, cast iron, and steel tube.

What does the 14/18 TPI rating mean and why does it matter for metal cutting?

The 14/18 TPI designation refers to a variable tooth pitch - the blade alternates between 14 and 18 teeth per inch along its cutting edge. This dual pitch helps balance aggressive material removal with a controlled, smooth cut, making it effective across a range of medium metal thicknesses from 1/16" to 5/16".

Are these blades compatible with cordless reciprocating saws?

Yes. These Diablo bi-metal blades are compatible with both corded reciprocating saws and cordless reciprocating saws, making them suitable for both powered jobsite setups and battery-operated tool systems.

What is Perma-SHIELD coating and how does it benefit metal cutting?

Perma-SHIELD is a non-stick coating applied to the blade body that protects against heat buildup, gumming, and corrosion during use. In metal cutting applications - where friction and heat are common challenges - this coating helps maintain consistent blade performance and extends the overall life of the blade.
