The Diablo DS0908CF3 9 in. 8 TPI Steel Demon Carbide Teeth Reciprocating Saw Blades are a 3-pack of carbide-tipped reciprocating saw blades built for thick metal cutting. This is a reciprocating saw blade designed for heavy metal demolition and cutting applications in stainless steel, cast iron, alloys, and other high-strength metals. Model Number: DS0908CF3.

What makes this blade matter is where it is meant to work. Diablo rates it for metal thickness from 3/16 in. to 9/16 in., which puts it squarely in the range where ordinary bi-metal blades tend to lose teeth, slow down, or get thrown away too soon. The 8 teeth per inch pattern is matched to thick metal work, giving you the bite needed for controlled cutting without being too fine for tougher stock.

Diablo uses high-performance carbide teeth and an enhanced tip-to-blade connection to improve durability and impact resistance. In plain terms, that means the teeth are built to stay working longer in punishing cuts, especially when you're into cast iron, stainless, or alloy material that chews through standard blades. The oversized 1 in. blade body also helps keep the cut straighter with less vibration and chatter, which is a real advantage when you're reaching through awkward metal assemblies or demolition work.

The Perma-SHIELD non-stick coating is not just a cosmetic add-on. It helps reduce heat and friction while resisting gumming and corrosion. On metal cutting jobs, excess heat is what shortens blade life fast, so a coating that helps manage that is worth paying attention to. If you cut thick material regularly, this is the kind of feature that saves downtime and blade changes.

These Diablo reciprocating saw blades are intended for use with corded or cordless reciprocating saws. They are a strong fit for metalworking, demolition, remodel crews, mechanical trades, and anyone cutting heavy steel, stainless, or cast iron where blade life actually matters. If your work is mostly thin sheet metal, this is more blade than you need. If you're cutting thick metal stock and want carbide durability, this is the right lane.
