Diablo 12" Bi-Metal Reciprocating Saw Blades for Nail-Embedded Wood bring professional-grade cutting performance to the toughest rough-in demolition tasks. Engineered with a variable tooth design at 4/6 TPI, these blades are built to power through nail-embedded wood, clean wood, rebar, angle iron, cast iron, and steel tube with speed and durability. The bi-metal construction extends blade life well beyond what standard single-material blades can offer, making them a dependable choice for contractors and tradespeople who demand consistent results from their corded or cordless reciprocating saw.

Key Features

• 12" blade length - provides extended reach into deep cuts and thick material, reducing the need to reposition while working
• Variable tooth design at 4/6 TPI - alternating tooth geometry balances cutting speed with control, delivering faster material removal and smoother results in nail-embedded wood
• Bi-metal construction - combines a tough, flexible body with an ultra-hard cutting edge to resist breakage and deliver significantly longer blade life compared to standard blades
• Optimized for nail-embedded wood - the blade geometry and material hardness allow it to power through embedded fasteners without stalling or premature dulling
• Compatible with corded and cordless reciprocating saws - universal fit supports both tool types, giving users flexibility on the job site without swapping blade sets
• Multi-material cutting capability - rated for clean wood, rebar, angle iron, cast iron, and steel tube, reducing the number of blade changes needed across mixed demolition work

Why This Product

• Designed specifically for nail-embedded wood applications, this blade handles the dual challenge of cutting through lumber and embedded metal fasteners without sacrificing speed or longevity - a common pain point with general-purpose blades
• The 4/6 TPI variable tooth pattern is engineered to cut faster through rough demolition material while reducing vibration, which means less operator fatigue during extended use
• Bi-metal technology delivers durability that goes well beyond single-material blades, making these a cost-effective choice for heavy demolition work where blade replacement is frequent
• The 12" length and broad material compatibility - from rebar to cast iron to steel tube - make this blade a versatile option for mixed rough-in and demolition work, minimizing time spent switching tools or blades

Frequently Asked Questions

What types of materials can these Diablo reciprocating saw blades cut through?

These blades are rated for clean wood, rebar, angle iron, cast iron, and steel tube - in addition to their primary application of nail-embedded wood. This broad material compatibility makes them well suited for mixed demolition and rough-in work.

What does the 4/6 TPI variable tooth design mean for cutting performance?

The 4/6 TPI designation refers to the variable tooth pattern, which alternates between tooth configurations to balance aggressive material removal with reduced vibration. This results in faster cuts and improved control compared to a fixed single-TPI blade.

Are these blades compatible with both corded and cordless reciprocating saws?

Yes. These Diablo bi-metal blades are designed to work with both corded reciprocating saws and cordless reciprocating saws, giving you flexibility to use them with the tools you already have on the job site.

Why choose bi-metal blades over standard reciprocating saw blades for nail-embedded wood?

Bi-metal blades combine a flexible alloy steel body with a hardened high-speed steel cutting edge. This construction resists snapping under the stress of hitting embedded nails and fasteners, while maintaining a sharp edge through extended cutting - giving you significantly longer blade life than standard single-material blades in demanding applications.
