Frequently Asked Questions

The Diablo D0770FA Steel Demon is a 7-1/4-inch, 70-tooth carbide-tipped blade designed for cutting thin mild steel. Its TiCo high-density carbide teeth and Triple Chip Grind (TCG) geometry are designed for controlled metal-cutting applications such as sheet metal, roofing and siding. It is specified for mild steel up to 18 gauge or thinner.

The Diablo D0770FA Steel Demon is designed for thin ferrous-metal applications, including roofing, siding, sheet metal, decking, corrugated sheets and steel studs. Use it for mild steel up to 18 gauge or thinner, and check the material thickness before cutting. It is not intended for stainless steel or thicker metal sections.

Look for carbide teeth designed for metal cutting, an appropriate tooth geometry and a blade body engineered for stability. The Diablo D0770FA features TiCo high-density carbide, 70-tooth Triple Chip Grind (TCG) geometry, a laser-cut steel body and anti-vibration technology. These features are designed to support controlled cutting in thin mild steel.

A protective coating can help reduce friction and heat build-up during metal cutting. The Diablo D0770FA features Perma-SHIELD non-stick coating, which is designed to resist heat build-up, gumming and corrosion. Cutting results still depend on the material, saw condition and correct operating technique.

Check the blade diameter, arbor size, maximum RPM and material compatibility against your saw manufacturer's requirements. The Diablo D0770FA has a 7-1/4-inch diameter, 5/8-inch arbor, 70 TCG teeth and a maximum rated speed of 5,800 RPM. Also confirm that your saw is suitable for metal cutting and that the workpiece is within the blade's specified thickness limit.

Use a metal-cutting blade designed for the thickness and type of steel, such as the Diablo D0770FA for mild steel up to 18 gauge or thinner. Secure the sheet firmly, support it close to the cutting line and follow the saw and blade manufacturers' operating instructions. Wear suitable eye, hearing and hand protection, and keep sparks and metal debris away from people and combustible materials.

Choose a blade designed for thin metal rather than using a general-purpose wood blade. The Diablo D0770FA combines 70 TCG teeth with a laser-cut blade body and anti-vibration technology, features designed to support stable cutting. Secure the roofing or siding properly and use a controlled feed rate to help maintain a consistent cut.

The Diablo D0770FA Steel Demon is a carbide-tipped alternative to abrasive cutting discs for suitable thin mild-steel applications. Its 70-tooth TCG design and TiCo carbide construction are intended for cutting corrugated sheets and other listed thin-metal materials. Check that the sheet is mild steel and no thicker than the specified 18-gauge limit.

The Diablo D0770FA Steel Demon is designed for thin mild-steel cutting with a compatible 7-1/4-inch circular saw. It has 70 TCG carbide teeth, a 5/8-inch arbor and a .071-inch kerf. Its listed applications include sheet metal, roofing, siding, decking, corrugated sheets and steel studs made from mild steel up to 18 gauge or thinner.

The Diablo D0770FA Steel Demon is a 7-1/4-inch carbide-tipped blade designed for thin mild-steel applications, including roofing and siding. Its TiCo high-density carbide teeth, 70-tooth TCG geometry and Perma-SHIELD coating make it suitable for these listed metal-cutting tasks when the material is within the specified thickness limit.

A carbide-tipped metal-cutting blade uses shaped teeth to remove material through a controlled cutting action, while an abrasive disc removes material through grinding. Diablo states that its Steel Demon blades can offer up to 40 times the life of standard abrasive discs, although actual service life depends on the material and working conditions. The D0770FA is designed for thin mild steel and requires a compatible circular saw.

A 70-tooth Triple Chip Grind (TCG) configuration uses alternating tooth profiles designed for cutting metal. The Diablo D0770FA combines this geometry with TiCo carbide construction for thin mild-steel applications. Tooth count alone does not guarantee a smoother finish, so choose a blade based on its intended material, thickness and cutting requirements.

Check the steel type and thickness first, then match the blade diameter, arbor, maximum RPM and application to your saw. The Diablo D0770FA is designed for mild steel up to 18 gauge or thinner and has a 7-1/4-inch diameter, 5/8-inch arbor and 5,800 RPM maximum rating. Do not use it for stainless steel or metal beyond its specified application.
