Brock Diablo Steel Demon Bi-Metal Auto Dismantling Saw Blades 25 Pack, 9in, 14/18 TPI

Overview

Meet Brock’s Diablo Steel Demon Bi-Metal Auto Dismantling Reciprocating Saw Blades. This 25-pack features 9 inch blades with 14/18 TPI, engineered for metal cutting tasks commonly encountered in auto dismantling and metal fabrication.

Constructed with a bi-metal composition, these blades balance a resilient core with tough teeth to handle tougher metals while maintaining flexibility. The Full Contact Arched Design is a standout feature that increases contact along the cut, helping you achieve faster progress in fewer passes and reducing heat buildup that can slow work. When used in the right context, the design can contribute to longer blade life and more consistent performance across multiple cuts.

Key design advantages

• Full Contact Arched Design enhances blade-to-metal contact for efficient cutting.
• Ultra hardened cutting edge provides durability under demanding tasks.
• Bi-metal construction blends toughness with flexibility to resist breakage.
• 14/18 teeth-per-inch (TPI) pattern is optimized for medium metals, including steel and aluminum alloys.

In real-world terms, you might notice faster progress on panels, braces, studs, or trim when dismantling automotive components or performing metal fabrication work. The combination of tooth geometry and edge hardness aims to minimize the number of passes required, which can help reduce heat generation and wear on the blade over time.

What you get and how to use it: a 25-pack of 9-inch blades designed for medium metal cuts, compatible with standard reciprocating saws. For best results, select the correct tooth pitch for the material and apply steady, controlled feeds, letting the blade do the work rather than forcing it. The blades are designed to perform well across a range of common dismantling tasks and can be used in professional settings or home workshops where metal cutting is part of the workflow.

Why choose Brock for metal cutting tasks

• Reliable life in comparison with standard blades, with dedicated life for repeated cuts.
• Consistent performance across cuts without excessive heat buildup.
• Intended for auto dismantling and general metal cutting in mid-thickness applications.
