Diablo Circular Saw Blade D0840X 8.25 Inch Finishing (40 Tooth ATB 5/8 Inch Arbor TiCo Carbide Hardwood Plywood Smooth Trim Crosscutting)

Diablo D0840X 8-1/4 Inch 40-Tooth TiCo Carbide Finishing Circular Saw Blade

The Diablo D0840X 8-1/4 Inch 40-Tooth Circular Saw Blade is a high-precision wood-cutting accessory engineered for ultra-smooth crosscuts in hardwood lumber, softwood boards, fascia trim, and plywood sheets. Formulated with TiCo High-Density carbide teeth in an Alternate Top Bevel (ATB) geometry operating at speeds up to 8,000 RPM, this 5/8-inch arbor blade eliminates tear-out on delicate veneer surfaces. Featuring a laser-cut 0.094-inch thin kerf, Perma-SHIELD non-stick thermal coating, and laser-cut stabilizer vents, this blade maximizes feed speed and battery efficiency across portable jobsite saws.

Best Used For:

• Hardwood & Softwood Trim Fitting: Slicing smooth, tear-free crosscuts in 1X finish boards, window casings, baseboards, and exterior fascia trim.
• Hardwood Plywood & Cabinet Sizing: Sizing cabinet grade plywood panels, oak veneer sheets, and melamine boards without top-layer splintering.
• Jobsite Decking & Fencing Crosscutting: Executing clean perpendicular cuts across pressure-treated deck boards, cedar fencing, and porch railing stock.

Key Performance & Safety Features

• TiCo High-Density Finish Carbide: High-density titanium cobalt carbide teeth resist abrasive friction wear to extend sharp cutting edge life.
• 40-Tooth Alternate Top Bevel (ATB) Pattern: Shearing tooth geometry slices cleanly across wood fibers to deliver smooth finished edges without splintering.
• Perma-SHIELD Non-Stick Coating: Fluoropolymer thermal barrier shields the steel plate against friction heat buildup, pitch gumming, and surface corrosion.
• Tri-Metal Shock-Resistant Brazing: Silver-copper-silver brazing layer absorbs severe impact force to prevent carbide tooth loss during high-speed ripping.
• 0.094-Inch Laser-Cut Super-Thin Kerf: Reduces material resistance and motor load to preserve battery runtime on portable circular saws.
• Laser-Cut Stabilizer Expansion Vents: Traps thermal expansion and absorbs mechanical vibration to keep cuts straight and minimize noise.

Pro-Tip: Set the blade depth so that only half a carbide tooth extends beyond the bottom face of the wood workpiece; maintaining minimal tooth projection reduces top-surface tear-out on delicate cabinet veneers.
