Diablo 9" Bi-Metal Reciprocating Saw Blades for Nail-Embedded Wood are purpose-built for demanding demolition and cutting tasks where nails, fasteners, and tough materials are part of the job. Crafted by Diablo and made in the United States, these 9-inch bi-metal recip saw blades feature a variable tooth design at 4/6 TPI, delivering aggressive cutting action through nail-embedded lumber while reducing vibration and improving blade control. Whether you are working through framing members loaded with nails, rebar, angle iron, cast iron, or steel tube, these blades are engineered to handle the punishment of real-world demo and renovation work.

Key Features

• 9" blade length with 4/6 TPI variable tooth design - the combination of coarse and finer teeth in a single blade allows for faster, more aggressive cuts through nail-embedded wood without sacrificing control or finish quality.
• Bi-metal construction - fuses a hardened cutting edge with a flexible body, giving the blade the durability to power through embedded nails and metal without snapping under stress, extending service life compared to single-material blades.
• Variable tooth geometry - alternating tooth pitch reduces vibration during cutting, making reciprocating saw work less fatiguing and helping you maintain straighter, more accurate cuts.
• Compatible with reciprocating saws and cordless reciprocating saws - fits the broadest range of professional and jobsite tools, so you can use these blades with both corded and battery-powered recip saws without needing adapters.
• Cuts clean wood, rebar, angle iron, cast iron, and steel tube - a single blade category covers multiple materials encountered in demolition, renovation, and framing applications, reducing the need to swap blades mid-task.
• Made in the United States - domestic manufacturing supports consistent quality control and reliable material sourcing.

Why This Product

• Designed specifically for nail-embedded wood - unlike general-purpose recip blades that can deflect or break when they hit hidden nails, these Diablo bi-metal blades are built to cut right through embedded fasteners, keeping your work moving without interruption.
• Handles mixed materials in one pass - because these blades cut clean wood, rebar, angle iron, cast iron, and steel tube, demolition crews can tear through framing, structural steel, and pipe without stopping to change blades for each new material.
• Bi-metal durability reduces replacement frequency - the hardened cutting edge bonded to a flexible body means the blade resists breakage even when flexing under load, so you get more cuts per blade and less downtime hunting for replacements on the jobsite.
• Variable tooth design works smarter, not just harder - the 4/6 TPI variable pitch actively dampens vibration, which translates to less fatigue over a long day of demolition cutting and more precise results in tighter spaces.

Frequently Asked Questions

What types of materials can these Diablo bi-metal recip blades cut?

These blades are rated to cut clean wood, rebar, angle iron, cast iron, and steel tube - making them a versatile choice for demolition, renovation, and structural work where multiple materials are encountered on the same job.

What reciprocating saws are compatible with these blades?

These 9" Diablo bi-metal blades are compatible with standard reciprocating saws and cordless reciprocating saws, covering the most common corded and battery-powered platforms used on the jobsite.

What does the 4/6 TPI variable tooth design mean in practice?

The 4/6 TPI designation indicates a variable tooth pitch - the blade alternates between 4 teeth per inch and 6 teeth per inch along its length. This variable geometry helps reduce vibration during cutting and allows the blade to move more aggressively through tough, nail-laden material while maintaining better control.

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

Bi-metal construction bonds a hardened cutting edge to a flexible body, which is essential when cutting through nail-embedded lumber. The hard edge maintains sharpness against metal fasteners, while the flexible body resists snapping under the lateral forces common in demolition work - giving you longer blade life and fewer unexpected breaks mid-cut.
