The Diablo Steel Demon 7-1/4 in. x 70-Tooth Carbide Saw Blade for Thin Metal (D0770F) is engineered for fast, accurate cutting through a wide range of mild steels using corded or cordless circular saws. Featuring Diablo's proprietary TiCo Hi-Density Carbide and a Triple Chip Grind (TCG) design, this metal cutting blade delivers burr-free, precise results with significantly fewer sparks than standard grinding discs. Whether you are cutting steel studs, corrugated sheet metal, roofing panels, or metal siding, the Steel Demon blade offers the controlled cutting action and long service life that demanding metal fabrication and construction work requires.

Key Features

• TiCo Hi-Density Carbide teeth - engineered exclusively for mild steel applications, delivering maximum cutting performance, superior cut quality, and longer blade life compared to standard grinding discs
• Triple Chip Grind (TCG) cutting geometry - reduces sparks during cutting, lowering the possibility of needing hot work permits on job sites and improving overall safety
• Optimized blade design - minimizes wandering and deflection of metal for precise, straight cuts that require virtually no re-work, saving time and material waste
• Advanced Laser Cut Stabilizer Vents - trap noise and vibration to maximize blade stability and keep the blade cool, resulting in straighter, more accurate cuts over extended use
• Tri-Metal Shock Resistant Brazing - a three-metal brazing system allows carbide teeth to withstand extreme impact, maximizing durability in tough metal cutting conditions
• Laser Cut Thin Kerf Design (.071 in. kerf) - reduces resistance and heat build-up for easier cutting, improved accuracy, and extended cutting life in both cordless and corded circular saws
• Perma-SHIELD non-stick coating - resists heat build-up by protecting the blade against gumming and corrosion, extending blade life in demanding metal cutting applications
• Laser Cut Arbor (5/8 in.) - reduces vibration and premature wear for accurate, consistent blade rotation throughout the cut
• Controlled cutting action with larger chip sizes - generates less dust and airborne contaminants versus standard grinding discs, contributing to a cleaner, healthier work environment
• Rated for mild steel 12 gauge or thinner - purpose-built for thin metal applications including roofing, siding, sheet metal, decking, corrugated sheet, and steel studs

Why This Product

• Contractors and tradespeople who cut steel studs, sheet metal, or corrugated roofing panels regularly need a blade that outlasts grinding discs - this blade's TiCo Hi-Density Carbide construction provides longer life and superior cut quality, reducing blade change frequency on the job
• Job sites with fire-sensitive environments benefit from the Triple Chip Grind cutting action, which reduces sparks compared to abrasive grinding discs and lowers the likelihood of hot work permits being required
• The thin kerf body requires less cutting power, making this blade an effective choice for cordless circular saws where battery efficiency matters - you get clean, fast cuts without taxing the tool
• The optimized blade geometry and Laser Cut Stabilizer Vents work together to minimize blade deflection and vibration, producing burr-free cuts in mild steel that require little to no finishing work after the cut

Frequently Asked Questions

What types of metal can this blade cut?

This blade is designed for mild steel only, rated for material that is 12 gauge or thinner. Compatible applications include steel studs, roofing panels, metal siding, sheet metal, decking, and corrugated sheets. It is not intended for use on stainless steel, hardened steel, or other non-mild steel metals.

Will this blade work with a cordless circular saw?

Yes. The Laser Cut Thin Kerf Design reduces resistance and heat build-up, which minimizes the cutting power required. This makes the D0770F well-suited for both cordless and corded 7-1/4 in. circular saws. The maximum speed rating is 8000 RPM.

How does the Triple Chip Grind reduce sparks compared to a grinding disc?

The Triple Chip Grind (TCG) tooth geometry is designed to produce a controlled cutting action that shears through thin metal cleanly rather than abrading it the way a grinding disc does. This controlled action results in larger chip sizes, fewer sparks, and less airborne dust and contaminants during cutting.

What is the arbor size, and will it fit my circular saw?

This blade features a 5/8 in. arbor, which is the standard arbor size for most 7-1/4 in. corded and cordless circular saws. Confirm your saw's arbor specification before installing to ensure compatibility.
