Bosch RM618 6-Inch 18TPI Metal Cutting Blades
Bosch’s RM618 blades utilize a bi-metal design with reinforced teeth and a thin kerf for faster, cleaner cuts in sheet metal, including aluminum. At 18 teeth per inch with a 0° hook angle, these blades effectively handle 10 to 16 gauge ferrous and non-ferrous metals. The blades’ toughness makes them well-suited for detailed and precision cuts where metal finishing matters.
EZARC Bi-Metal Cobalt 6-Inch 14TPI Heavy Metal Blades
The EZARC blades feature M42 cobalt teeth, enhancing heat resistance for sustained heavy-duty cutting of metal pipes and aluminum profiles. Their cobalt edge optimizes wear resistance, making it an excellent choice for demanding projects involving thick aluminum or metals. The 14 TPI tooth count strikes a balance between cutting speed and finish, suitable for medium-to-heavy metal cutting applications.
Diablo Steel Demon Carbide Teeth 6-Inch 3 TPI Blades
Designed for extreme metal cutting tasks, the Diablo Steel Demon blades incorporate carbide teeth for exceptional durability and cutting performance on thick metals ranging from 3/16″ to 9/16″. Their 3 TPI tooth configuration specializes in fast, aggressive cuts with less vibration. These 6-inch blades are best suited for thick aluminum sheets or bars where patience is required for precision and blade longevity.
AMARTISAN Heavy Metal Cutting 6-Inch 14TPI Blades
The AMARTISAN set delivers five 6-inch bi-metal blades with 14 TPI, engineered for smooth, efficient cutting of medium-thickness aluminum sheets, pipes, and steel bars. Their high-quality bi-metal construction ensures heat resistance and toughness, extending blade life during prolonged use. This combo suits professional and DIY users seeking reliable performance across a variety of metal types.
Buying Guide for Reciprocating Saw Blades for Aluminum
Blade Material
Bi-metal blades offer excellent flexibility and durability through the combination of high-speed steel and flexible alloy steel. For tougher or thicker aluminum, cobalt-infused or carbide-tipped blades enhance heat resistance and blade life but may cost more.
Teeth Per Inch (TPI)
Higher TPI blades (18-24 TPI) provide cleaner, precise cuts ideal for thin aluminum sheets. Lower TPI blades (3-14 TPI) cut faster but leave rougher edges, better suited for thicker materials or demolition. Selecting TPI depends on aluminum thickness and desired finish.
Blade Length
Standard lengths for reciprocating saw blades in aluminum cutting range around 6 inches, offering a good balance between reach and control. Longer blades may be necessary for deeper cuts but can reduce stability.
Cutting Application
Consider the specific aluminum forms—sheet, pipe, or bar. Thin sheets require fine-tooth blades with a zero or positive hook angle for smoothness, while thicker pipes benefit from low TPI, robust tooth profiles designed for heavy-duty cutting.
Durability and Heat Resistance
Cutting aluminum generates heat, impacting blade longevity. Blades made with cobalt or carbide teeth resist heat and maintain sharpness longer. Bi-metal blades offer good durability for general applications but may wear faster under heavy use.
Brand Reputation and Value
Established brands like DEWALT and Bosch are trusted for consistent quality and innovate designs. Consider pack size and blade versatility to ensure cost-effectiveness, especially for frequent users.
