DEWALT, DT2974-QZ, 43 cm Alligator Tandem Saw Blade

This 430 mm DEWALT alligator tandem saw blade is a replacement cutting component for compatible DEWALT alligator saws used in construction, masonry, and renovation work. It is designed to cut Class 12 Poroton blocks, wood, plywood, chipboard, and drywall. Its tandem format positions two cutting edges in line for controlled cuts through dense building materials, producing clean results across these demanding substrates. Professional tradespeople and experienced DIY users can fit it to restore cutting performance without replacing the entire saw.

The blade has tungsten carbide-tipped teeth for durable cutting in abrasive masonry environments. It fits DEWALT DWE396, DWE397, DWE398, and DWE399 alligator saw models. Each pack supplies one replacement tandem blade. The carbide edges hold their sharpness through repeated use in Poroton blocks and plywood panels, so users can swap a worn blade and return to work without changing machines.

• 100 mm maximum cutting depth at 90° — handles thick Poroton blocks in a single pass
• 48 teeth — balances cutting speed with finish quality across mixed materials
• Tungsten carbide edge material — a hard edge compound for wear resistance in abrasive substrates
• 430 mm working length — tandem format matched to DEWALT alligator saw cutting geometry
