The Diablo Steel Demon 12" 8 TPI Carbide Teeth Reciprocating Blades for Thick Metal deliver a serious performance upgrade for professionals tackling demanding metal cutting tasks. Engineered by Diablo and sold in a convenient pack of 10, these carbide-tipped recip blades are purpose-built for cutting thick metals ranging from 3/16" to 9/16" - including rebar, angle iron, cast iron, steel tube, and high-strength alloys. With 50x longer cutting life compared to standard bi-metal blades, the Steel Demon line redefines what a reciprocating saw blade can do in extreme heavy-metal applications.

Key Features

• TiCo Hi-Density Carbide Teeth - delivers greater durability and sustained cutting performance through tough metals in the 3/16" to 9/16" thickness range, so blades stay sharp far longer through demanding cuts
• Enhanced carbide tip to blade connection - engineered for extreme impact resistance, meaning the carbide tips stay bonded even when cutting through hard, abrasive materials like cast iron and stainless steel
• 1" oversized blade body - provides a wider, more rigid cutting platform that produces straighter cuts with noticeably less vibration, reducing operator fatigue on long cutting sessions
• Perma-SHIELD non-stick coating - reduces heat buildup and friction during cutting, which extends blade life and keeps the blade moving freely through metal without binding
• 12" blade length at 8 TPI - the longer blade reach combined with an 8-tooth-per-inch configuration is optimized specifically for aggressive, efficient cutting through thick metal stock
• Pack of 10 blades - provides a ready supply for high-volume job sites or professional crews who depend on consistent blade availability without constant reordering

Why This Product

• Professionals cutting rebar, angle iron, cast iron, or steel tubing regularly face blade wear and frequent blade changes - the 50x longer cutting life of these carbide-tipped blades directly reduces downtime and consumable costs on the job
• High-strength alloys and stainless steel are notoriously hard on standard bi-metal blades - the TiCo Hi-Density carbide formulation is specifically designed to handle these extreme materials without rapid dulling
• The 1" oversized body and Perma-SHIELD coating work together to address two common pain points in metal recip cutting - blade wander and heat-induced friction - resulting in more precise, controlled cuts with less physical effort
• Compatible with both corded reciprocating saws and cordless reciprocating saws, making these blades versatile across a wide range of tool setups already in use on the job site

Frequently Asked Questions

What makes these blades different from standard bi-metal reciprocating blades?

These Diablo Steel Demon blades use TiCo Hi-Density carbide teeth rather than the bi-metal construction found in conventional recip blades. This carbide formulation delivers up to 50x longer cutting life in thick metal applications from 3/16" to 9/16", making them a far more cost-effective choice for heavy-duty or high-volume metal cutting compared to replacing standard blades repeatedly.

What types of metal can these blades cut?

These blades are designed for thick metal cutting in materials including rebar, angle iron, cast iron, steel tube, high-strength alloys, and stainless steel. They are optimized for material thicknesses in the 3/16" to 9/16" range.

Will these blades fit my existing reciprocating saw?

These 12" blades are compatible with both corded reciprocating saws and cordless reciprocating saws. As with any recip blade, verify that your saw accepts standard reciprocating blade shanks before use.

What does the Perma-SHIELD coating do during metal cutting?

The Perma-SHIELD non-stick coating applied to the blade body reduces heat and friction as the blade moves through metal. Less heat means less blade distortion and less material buildup on the blade surface, which helps maintain cutting efficiency and contributes to longer overall blade life in demanding thick-metal applications.
