Diablo Circular Saw Blade D0770FM 7 Inch Disc (70T TCG TiCo Carbide 8000 RPM 20mm Arbor Thin Kerf Sheet Metal Steel Studs Roofing Siding Slicing Tool)

Diablo D0770FM 7" 70-Tooth Steel Demon™ TiCo™ Carbide Thin Metal Circular Saw Blade

The Diablo D0770FM 7-inch 70-tooth Steel Demon™ circular saw blade slices light-gauge steel framing studs, trims corrugated metal roofing panels, crosscuts standing-seam siding sheets, and sections thin-wall steel ductwork without generating hot slag or rough edge burrs. Engineered with proprietary TiCo™ high-density carbide teeth mounted to a 20mm (0.787 in) arbor plate and rated for operating speeds up to 8,000 RPM, this precision wheel delivers 50X cooler cuts than abrasive cutoff wheels in mild steels measuring 18-gauge (0.0478 in) or thinner. Outfitted with a specialized Triple Chip Grind (TCG) profile with a -5° negative hook angle, a thin 0.071-inch kerf, and a Perma-SHIELD® non-stick thermal barrier, it equips commercial drywall framers, metal roofing contractors, and HVAC fabricators with spark-controlled, burr-free cuts across corded and cordless metal-cutting circular saws.

Best Used For:

• Light-Gauge Steel Stud Framing: Slicing 20-gauge and 25-gauge interior steel drywall studs, track runners, and bridging channels without edge flaring.
• Corrugated Metal Roofing and Siding: Trimming prepainted steel roofing panels, standing seam sheets, and ribbed siding without burning protective zinc coatings.
• Thin-Wall Sheet Metal and Ductwork: Sectioning galvanized spiral HVAC pipe, sheet metal flashing, and steel electrical enclosures cleanly with minimal sparks.

Key Performance & Safety Features

• TiCo™ Hi-Density Carbide Teeth: Custom-formulated micro-grain carbide tips resist severe abrasive wear in mild steel to outlast standard abrasive wheels.
• Triple Chip Grind (TCG) Tooth Geometry: Balances chip load across 70 precision teeth to produce cool-to-the-touch, burr-free cuts ready for immediate installation.
• 50X Cooler Cutting Action: Produces clean metallic chips rather than hazardous airborne grinding dust, often eliminating hot work permits on sensitive job sites.
• Perma-SHIELD® Non-Stick Coating: Thermally bonded barrier shields the blade body from friction heat, gummy residue buildup, and atmospheric corrosion.
• Laser-Cut Thin 0.071-Inch Kerf: Narrow cutting width reduces power draw and motor drag to extend battery runtime on cordless circular saws.
• Laser-Cut Stabilizer Noise Vents: Polymer-filled expansion slots trap harmonic vibration and suppress high-frequency chatter to keep cuts straight and accurate.
• Tri-Metal Shock Resistant Brazing: Advanced silver-copper-silver brazing allows carbide teeth to absorb heavy mechanical shock without shearing off the plate.

Technical Specifications

Pro-Tip: When trimming corrugated steel roofing or thin metal siding panels, clamp a straight wood guide board over the cut line to prevent thin sheet flutter; maintaining rigid workpiece support allows the 70 TCG carbide teeth to shear through the steel cleanly without warping the ribs.
