EZARC 25 Pack Bi-Metal Cobalt Reciprocating Saw Blades - Heavy Metal

In this review the EZARC 25 Pack Bi-Metal Cobalt reciprocating saw blades are evaluated for tradespeople and serious DIYers who need a durable blade pack for metal demolition and fabrication. The single biggest reason to buy is the M42 bi-metal edge with 8% cobalt teeth, which is engineered to resist heat and hold cutting performance when working through medium-thick sheet metal and metal pipes. For anyone regularly cutting metal where blade life and consistent performance matter, this pack offers a practical balance of durability and value.

Key Features

• 8% Cobalt Teeth: The M42 bi-metal construction with cobalt is designed to endure higher temperatures and maintain edge life during demanding metal cutting tasks.
• Metal Cutting Optimized: Tooth geometry and materials are tuned to cut sheet metal, pipes and profiles efficiently for cleaner, more controlled cuts on metal workpieces.
• Durability for Demolition: The blades are engineered with enhanced wear resistance to withstand tougher demolition and heavy use without failing prematurely.
• Cutting Capacity: Suitable for medium-thick sheet metals from about 3-10mm and metal pipes or profiles under 100mm in diameter, providing useful versatility on jobsites.
• Universal Shank: The 1/2 in shank fits the vast majority of reciprocating saws on the market, making the set interchangeable across common tool brands.
• Value Pack: A 25-pack supply reduces downtime and gives long-term work support for repeated cutting tasks without frequent reordering.

Who It's For

The EZARC cobalt reciprocating blades are best for professional contractors, metal fabricators and serious DIYers who cut sheet metal, conduit, exhausts, metal barrels and similar materials where heat and wear are concerns. They suit users who need a large quantity of blades for continuous work and want a blade that resists bending when cutting thicker mild steel.

Those who primarily cut wood, laminated materials or very thin nonferrous metal might prefer blades optimized for those substrates, and users needing ultra-precision trim cuts or very long-life specialty alloy blades should look to more specialized options. For general metal demolition and maintenance tasks, however, these blades are a sensible choice.

Pros & Cons

Pros

• High-temperature resistant 8% cobalt edge that extends cutting life under heavy metal use.
• Reliable performance across sheet metal and pipe work, giving cleaner, faster cuts than generic blades.
• The universal 1/2 in shank works with most common reciprocating saws, simplifying tool compatibility.
• A large 25-pack provides good value and reduces the need to restock frequently.

Cons

• Durability feedback is mixed; some users report blades wear sooner than expected when cutting abrasive or very thick steels.
• Not optimized for wood or composite materials, so performance will be inferior on non-metal tasks.
