Polycrystalline Diamond Track Saw Blade with 4 teeth — a purpose-built solution for cutting hard fiber cement and other dense materials. Designed to work with common track saws, this blade combines Longevity, precision, and speed to help you complete Hardie board projects—from siding and trim to panels—with consistent, professional results.\u003c\/p\u003e \u003cp\u003eThe secret is the polycrystalline diamond (PCD) edge. Unlike traditional carbide blades, the PCD edge resists wear and maintains an exceptionally sharp cut, which translates to longer blade life and cleaner edges even after repeated passes through Hardie board and similar cementitious substrates. The 4-tooth configuration delivers aggressive removal for quicker cuts through tough materials, while the slim 0.07\" kerf minimizes waste and reduces the load on your saw for smoother operation at higher RPMs.\u003c\/p\u003e \u003ch3\u003eKey specifications at a glance\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 6-1\/2\" (165 mm)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eArbor size:\u003c\/strong\u003e 20 mm\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eTeeth:\u003c\/strong\u003e 4\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eKerf:\u003c\/strong\u003e 0.07\" (thin kerf for efficient cuts)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polycrystalline Diamond (PCD)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMaximum speed:\u003c\/strong\u003e 8,800 RPM\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Bosch, DeWalt, Makita, Milwaukee, Ryobi track saws\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Clamshell\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBrand\/Sub-brand:\u003c\/strong\u003e Diablo \/ James Hardie\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWho this blade is best for\u003c\/h3\u003e\n\u003cp\u003eIdeal for professional remodelers, cabinetmakers, and serious DIYers who frequently work with fiber cement—especially James Hardie Hardie board siding, trim, and panels.
