DEWALT Reciprocating Saw Blades, 6-Inch 24 TPI, 5-Pack
These straight-back, bi-metal blades are designed for long-lasting cutting edge and flexibility. The blades are manufactured with hardened teeth for durability and are made in the U.S. with global materials, making them a reliable choice for metal demolition tasks. The 24 TPI configuration provides a balance of fast cutting and smooth finish in thicker metal sections such as conduit, pipe, and sheet metal. A good all-around option for professionals who perform frequent metal cutting.
EZARC Carbide Reciprocating Saw Blade R678HM Endurance
EZARC’s carbide-blade lineup emphasizes longevity, offering up to significantly longer life than traditional bi-metal blades. With an 8 TPI configuration, these blades excel in tough metal applications such as high-alloy steel, stainless steel, rebar, and vehicle frames. The carbide technology enables easier cuts through hard metals that typically dull standard blades, delivering consistent performance in demanding demolition or fabrication tasks.
TOLESA Heavy Metal Cutting Reciprocating Blades
TOLESA blades are designed for heavy metal cutting, featuring a sturdy cobalt edge within a bi-metal construction for efficient cuts into sheet metal, pipes, and profiles up to seven inches in diameter. The 0.9 mm thin-wall design reduces heat buildup, while the 14 TPI teeth provide faster cutting speeds and longer blade life in demolition work. This set is a solid option for professionals cutting through thick metal sections without frequent blade changes.
Diablo 14 Piece Bi-Metal Reciprocating Saw Blade Set
This set provides versatility for both wood and metal demolition. It includes the top-selling Diablo Demo Demon and Steel Demon blades and features patented variable tooth technology to speed cuts while reducing vibration. The assortment covers a range of tasks, including nail-embedded wood and heavy metal demolition, with different lengths and tooth configurations to optimize cutting performance across materials.
Caliastro 8-Pack Bi-Metal Blades For Metal
The Caliastro blades are built for reliability in metal cutting, using a high-quality bi-metal construction with thicker cross-section and durable teeth designed to withstand the stresses of cutting metal up to quarter-inch thickness. The 18 TPI configuration supports steady progress in thicker materials like conduit, pipe, and structural steel, while minimizing blade deflection and breakage in demanding cutting scenarios.
Buying Guide: Key Considerations For Metal Blade Purchases
- Material compatibility: Bi-metal blades balance flexibility and life for most metals, while carbide blades excel in hard alloys and stainless steel. Identify the primary metals you’ll cut to choose the right technology.
- TPI (teeth per inch) and cut speed: Higher TPI offers smoother cuts in thinner metal and nail-removal tasks but may cut slower in thick sections. Lower TPI blades cut faster in heavy metal but wear quicker.
- Blade length and thickness: Longer blades reach into deeper cuts; thicker blades resist bending under load. For metal demolition, 6 to 9 inches is a common range, with 0.9 mm thin-wall designs helping reduce heat buildup.
- Durability features: Look for cobalt edge, bi-metal construction, or carbide tips to improve longevity under demanding conditions and minimize blade changes on job sites.
- Compatibility: Ensure the blade shank type matches your reciprocating saw. Most blades in this guide use standard universal shanks common to major brands.
- Heat management: Designs that minimize heat generation reduce blade warping and extension of blade life, especially during prolonged cuts in thick metal.
- Value and set options: Multi-packs provide a balance between upfront cost and long-term savings, but consider whether you need mixed-length blades or a dedicated length for your project.
When outfitting a tool kit for metal demolition or fabrication, a mix of carbide and bi-metal blades is often ideal. Carbide blades excel in hard, high-alloy metals, while bi-metal blades provide flexibility and durability for general metal cutting. Always follow manufacturer safety guidelines, wear appropriate PPE, and select blades that fit your saw’s specifications for optimal performance and safety.
