Diablo D0604DH 6-1/2" 4-Tooth HardieBlade™ PCD Diamond Fiber Cement Circular Saw Blade

The Diablo D0604DH 6-1/2-inch 4-tooth HardieBlade™ circular saw blade crosscuts fiber cement lap siding, rips architectural exterior wall panels, trims soffits, and sections cementitious backer boards without abrasive edge dulling. Engineered with polycrystalline diamond (PCD) tips mounted via tri-metal shock-resistant brazing and rated for operating speeds up to 10,000 RPM, this 5/8-inch arbor disc delivers up to 75X longer cutting life compared to standard carbide blades. Featuring a specialized PCD Triple Chip Grind (TCG) profile with an ultra-thin 0.071-inch kerf that reduces respirable dust generation by up to 50%, alongside a Perma-SHIELD® non-stick thermal coating, it equips professional siding contractors, exterior remodelers, and finish carpenters with clean, chip-free cuts across corded and cordless 6-1/2" circular saws.

Best Used For:

Technical Specifications

Pro-Tip: When cutting fiber cement siding planks on a 6-1/2" cordless circular saw, maintain a steady forward feed and cut with the decorative face down; this positions the downward tooth stroke toward the finished surface to guarantee flawless, chip-free lap edges.
