Diablo Saw Blades D0704DHA-5 7-1/4 Inch 4-Tooth (5-Pack PCD Diamond HardieBlade 5/8 Knockout Arbor Fiber Cement Siding Cutting Circular Tool)

Diablo D0704DHA-5 7-1/4" 4-Tooth PCD HardieBlade Fiber Cement Saw Blades 5-Pack

The Diablo D0704DHA-5 5-pack of 7-1/4-inch 4-tooth Polycrystalline Diamond (PCD) tipped HardieBlade saw blades cuts fiber cement siding panels, backerboard underlayment, and trim boards with up to 50% less respirable dust. Engineered with a specialized Triple Chip Grind (TCG) tooth profile that delivers over 75X longer service life compared to conventional carbide blades, this 10,000 maximum RPM blade utilizes a thin 0.071-inch kerf to maximize cordless circular saw battery efficiency. Outfitted with laser-cut anti-vibration stabilizer vents, a 5/8-inch arbor with diamond knockout, and a heat-resistant Perma-SHIELD coating, it equips professional siding installers and general contractors with clean, chip-free fiber cement cutting endorsed by James Hardie Building Products.

Best Used For:

• Fiber Cement Lap Siding and Panel Installation: Slicing HardiePlank, Cemplank, and architectural fiber cement panels with clean, factory-grade edge finishes.
• Tile Backerboard and Cement Underlayment Cutting: Cutting dense HardieBacker and cementitious subfloor sheets without abrasive tooth wear.
• Exterior Fiber Cement Trim Fabrication: Trimming thick HardieTrim boards and soffits accurately while drastically suppressing airborne silica dust.

Key Performance & Safety Features

• Polycrystalline Diamond (PCD) Tipped Teeth: Spark-eroded diamond cutting edges resist the severe abrasion of silica cement, delivering over 75X extended cutting life.
• 50% Dust Reduction Design: Optimized 4-tooth configuration generates larger, heavier particles that settle quickly to minimize respirable airborne dust clouds.
• Triple Chip Grind (TCG) Geometry: Alternating flat and trapezoidal tooth shapes shear abrasive composite substrates cleanly to prevent blow-out and edge chipping.
• Thin 0.071-Inch Laser-Cut Kerf: Reduces motor resistance and cutting friction, maximizing cuts per charge on portable cordless circular saws.
• Perma-SHIELD Non-Stick Thermal Barrier: Proprietary protective coating shields the steel plate against frictional heat buildup, gumming, and corrosion.
• 5/8-Inch Arbor with Diamond Knockout: Fits standard circular saw arbors and knocks out easily for high-torque worm-drive saws.

Pro-Tip: When cutting stacks of fiber cement lap siding, keep your saw moving with a continuous, steady feed rate and avoid stopping mid-cut; consistent feed momentum allows the 4-tooth PCD geometry to eject heavy dust chips efficiently without creating fine airborne particles.
