10 Best Sawzall Blades 2026 in the United States

The Diablo Steel Demon Carbide Teeth Reciprocating Saw Blades are specifically designed for extreme metal cutting, making them an excellent choice for those who frequently work with high-strength alloys, cast iron, and stainless steel. With a carbide tooth design and an 8 TPI (teeth per inch) count, these blades offer superior cutting power and durability.

The 9-inch blade length and 0.56-inch thickness contribute to their robustness, allowing for clean and accurate cuts due to the 1-inch oversized blade body which reduces vibration and chatter. Additionally, the Perma-SHIELD Non-Stick Coating helps the blades resist heat, gumming, and corrosion, enhancing their lifespan and performance.

Each blade is ultra-hardened with TiCo Hi-Density carbide, promising up to 50 times longer cutting life compared to standard bi-metal blades in extreme metal applications. The 10-pack ensures you have plenty of replacements available for extended projects. However, the specialized design and materials may make these blades more expensive than standard options, and their 8 TPI might not be as effective for finer cuts in thinner materials. For heavy-duty cutting tasks, their performance and durability are hard to beat, making them a valuable investment for professionals and serious DIY enthusiasts.

These Diablo Steel Demon sawzall blades come in a 25-pack, each blade measuring 9 inches long with a thickness of 0.06 inches. They are made of alloy steel, known for durability and resistance to wear, which makes them suitable for cutting medium metals. The blades have a tooth count that varies between 14 and 18 TPI (teeth per inch), providing a good balance between speed and smoothness of the cut—14 TPI is better for faster, rougher cuts, while 18 TPI offers finer control. The bi-metal construction typically means the blades combine flexibility with toughness, reducing the risk of breaking during demanding jobs.

These blades are designed specifically for auto dismantling and similar metal cutting tasks, which aligns well with their medium metal suitability. At 0.06 inches thick, they are not the thinnest blades available, which might slightly affect cutting speed but adds strength. The pack size is generous for frequent users or those working on multiple projects. These blades might be less ideal for very fine or delicate cuts where a higher TPI or thinner blade would perform better.

The product is branded Brock but marketed under Diablo Steel Demon style, which could cause some confusion. This set is a solid choice for people who need reliable, durable blades for medium metal cutting in automotive or similar work, offering durability and versatility without specialized features for ultra-precision cutting.

The Diablo Bi-Metal Reciprocating Blades stand out for their strong build and thoughtful design, making them a solid choice for cutting medium-thickness metal. Made from bi-metal, these blades offer durability and flexibility, which helps prevent breakage during tough jobs. The 9-inch length is versatile, fitting most standard sawzalls and allowing for deeper cuts when needed. With a dual tooth configuration of 14 and 18 teeth per inch, the blade strikes a good balance between speed and smoothness when cutting metal.

The unique full contact arched design helps speed up cutting by reducing heat and requiring fewer passes, enabling more efficient work. The Perma-Shield coating adds protection against rust, heat damage, and sticky residue, which means the blades last longer even under harsh conditions. The 1-inch thick demolition body helps reduce vibration, providing more control and straighter cuts.

While these blades excel at cutting medium metal, they may not perform as well on very thick or very soft materials like wood, where different tooth designs or lengths might be better. The pack of 25 is suitable for frequent heavy use but could be more than needed for occasional DIY tasks. These blades are tailored for professionals or serious DIYers focused on metal demolition and cutting, offering a blend of durability, speed, and precision.
