DeWalt 115mm PCD Fibre Cement Saw Blade for DCS571

The DeWalt DT20421 is a specialist 115mm circular saw blade engineered for cutting fibre cement materials with the DCS571 cordless circular saw. Featuring synthetic polycrystalline diamond (PCD) teeth, this blade delivers the durability and cutting performance required for one of the most abrasive materials encountered on site.

Fibre cement board presents unique challenges for cutting tools due to its highly abrasive silica content, which rapidly wears conventional carbide-tipped blades. The PCD tooth construction of this blade is specifically designed to withstand these harsh conditions, providing extended service life when working with cement boards, fibre cement cladding, and similar composite materials.

With just four PCD teeth and a compact 115mm diameter, this blade is optimised for the DCS571's cordless platform, ensuring efficient cutting without excessive battery drain. The 9.5mm bore provides secure mounting, whilst the 5000 RPM maximum speed rating matches the saw's capabilities for safe, controlled operation.

Ideal for roofing contractors, cladding specialists, and construction professionals regularly working with fibre cement products, this blade delivers reliable performance in demanding applications where standard blades fall short.
