Reciprocating Saw Blades 9 in 6/12 TPI Bi-Metal 25 Pack - Nail Duty

In this review the focus is on a 25-pack of 9 in reciprocating saw blades designed for demolition and nail-embedded wood. The reviewer finds these blades most useful for homeowners and contractors who tackle fence removal, remodeling, and demolition where embedded nails are expected. The single biggest reason to buy is durability against nails: the blades are bi-metal with extra cobalt and a thicker 1.27mm body, which translates to longer life and less worry about sudden breakage when cutting through wood with fasteners.

Key Features

• Bi-metal construction: The high-density bi-metal with added cobalt increases edge life when cutting through wood and nails compared with plain carbon blades.
• 6/12 TPI variable teeth: Variable tooth geometry delivers faster, smoother cuts with reduced vibration across mixed material thicknesses.
• Thickened blade body: At about 1.27mm thickness these blades resist bending and lower the risk of sudden breakage during tough demolition work.
• Nail-embedded wood performance: Specifically tuned for wood with nails so you can trim old fences and scrap lumber without frequent blade changes.
• Wide material compatibility: Works on common lumber, OSB/plywood, PVC/PE, screws, nails and light metal demolition, making it a versatile pack for jobsite tasks.
• Universal shank: Fits major reciprocating saw brands, simplifying blade swaps across different tools.

Who It's For

The blades are best for DIYers, renovators and professional carpenters who regularly cut reclaimed lumber, remove fences or do light demolition where nails and screws are present. The 25-pack format suits users who want a ready stock of disposable blades for continuous jobsite work.

Those who primarily cut thick metal, fine finish woodwork, or need ultra-fine cuts for cabinetry should look elsewhere for blades optimized for metal-only or finishing tasks, as these are designed as demolition blades with a balance toward durability rather than fine finish.

Pros & Cons

Pros

• Good durability when encountering nails due to bi-metal plus extra cobalt construction.
• Variable 6/12 TPI tooth pattern gives faster cutting with less vibration across mixed materials.
• Thicker 1.27mm blades reduce risk of breakage and improve stability in aggressive cuts.
• Universal shank lets these blades be used with a wide range of reciprocating saw brands.

Cons

• Not optimized for precision finish cuts; intended for demolition and rough work.
• Some customers report mixed durability, so performance can vary with cutting technique and material hardness.

Specifications

Our Verdict

These 9 in bi-metal reciprocating blades are a practical choice for demolition and nail-embedded wood tasks, offering a durable balance of cut speed and toughness. For anyone doing fence removal, framing tear-out or mixed-material demolition, the thicker cobalt-enhanced blades deliver good value; those needing fine finish blades should choose a different blade type.
