Score: 92/100Rankings
The Metabo HPT NR90AES1 is a highly reliable pneumatic framing nailer designed for heavy-duty construction, featuring a lightweight 7.5 lb body and a 5-year warranty. Its main trade-off is the need for regular oiling and a compressor, which limits portability compared to cordless options. It is best suited for professional framers and carpenters who prioritize durability and lightweight ergonomics.
The NuMax SFR3490 is a lightweight pneumatic framing nailer featuring a 34-degree clipped head design for accessing tight spaces like joists and trusses. It offers dual-mode firing (bump or sequential), tool-free depth adjustment, and anti-dry-fire protection to enhance safety and reduce fatigue during framing, sheathing, and pallet assembly tasks. It is best suited for DIYers and light professional contractors needing an affordable pneumatic nailer for occasional framing tasks.
