Metabo HPT NR3675DD 36V MultiVolt 3-1/2" Cordless Duplex Nailer

Think about the sheer amount of time and physical energy your crew wastes manually hammering double-headed duplex nails into temporary concrete forms, wood scaffolding, or foundation framing. It is tedious, exhausting work that slows down the entire jobsite momentum. This Metabo HPT NR3675DD eliminates that bottleneck by bringing the world’s first dedicated cordless solution to temporary wood structures. You get the blistering speed of a pneumatic production line combined with complete cordless freedom, no air compressors, no tangled hoses, and no loud gas fuel cells required.

The real engineering breakthrough here is the unique mechanical drive system. Unlike gas-powered nailers that require expensive, smelly fuel cartridges and constant cleaning, this tool uses a sealed compressed air system driven by a powerful brushless motor. It fires up to two nails per second with zero ramp-up time, sinking duplex nails flush against their first head every single time while leaving the top head perfectly exposed for effortless extraction later. Powered by high-capacity 36V MultiVolt battery technology, this nailer drives up to 900 nails on a single charge, keeping your team moving through large-scale concrete pours without interruption.

Safety and on-the-job convenience are built into every corner of this heavy-duty tool. It features a tool-less depth of drive adjustment so you can instantly adapt to different lumber densities, alongside a dry-fire lockout mechanism that stops the tool from firing when your nail count is low, protecting the internal firing pin from unnecessary wear. When it is time to strip the forms down, the integrated extra-wide pivoting rafter hook lets you securely hang the tool from scaffolding or a tool belt, keeping your hands free and your equipment safe from accidental drops.

Highlights:

• World's First Cordless Duplex Solution: Engineered specifically to drive double-headed duplex nails into concrete forms and temporary scaffolding at production speeds.

• Zero Ramp-Up Air Spring System: Uses sealed, pressurized air to fire nails instantly with the feel of a pneumatic tool, eliminating the lag time found in other cordless nailers.

• Eco-Friendly Brushless Motor: Delivers maximum runtime and motor life while running completely free of expensive, foul-smelling gas fuel cells.

• Massive All-Day Productivity: Drives up to 900 duplex nails per charge when paired with a standard MultiVolt battery, keeping downtime to an absolute minimum.

• Dry-Fire Lockout Protection: Automatically prevents the tool from cycling when the magazine reaches the last few nails, preventing blank fires and extending tool life.
