DEWALT DT2975-QZ Alligator Saw Blade 430 mm for Aerated Concrete

The DEWALT DT2975-QZ is a 430 mm alligator saw blade designed as a replacement for DEWALT alligator saws. It is intended for alligator saws, which use a reciprocating cutting action rather than the circular rotation of standard saws. The 430 mm length matches the original equipment specification for compatible models. This blade type is specific to alligator saws and cannot be interchanged with circular or standard reciprocating saw blades. Replacement blades restore cutting performance when the originals become worn or damaged after extended use.

The blade uses TCT (tungsten carbide tipped) teeth for cutting concrete materials. Tungsten carbide tipped teeth are chosen for their wear resistance when cutting abrasive lightweight concrete, which can wear down standard steel teeth more quickly. The TCT tooth design also produces clean, accurate cuts in these materials. This construction holds its tooth geometry longer than non-tipped alternatives in similar applications. The carbide tips provide a harder cutting edge than standard steel, which is needed for cutting aerated and cellular concrete blocks effectively.

• Suitable for aerated concrete, gas concrete, and cellular concrete blocks – covers three common lightweight concrete types
• Compatible with DEWALT DWE397, DWE398, and DWE399 – direct replacement for three alligator saw models
• Designed for construction, renovation, and masonry work – suited to typical lightweight concrete applications
• One blade per pack – a single replacement for restoring cutting performance
• TCT (tungsten carbide tipped) teeth – resist abrasive wear for longer blade life on concrete
