The first of its kind, the Grex GC1850 cordless brad nailer is powered by 2 AAA batteries and fuel cell only. Capable of driving 18 gauge brad nails up to 2" in length, the Grex GC1850 is the only cordless brad nailer that is as small as a traditional air-operated finish nailer. An industry first, this cordless brad nailer is powered by 2 AAA alkaline batteries - that last at least 50,000 shots; and a fuel cell that lasts approximately 1,300 shots per cartridge. This Grex brad nailer eliminates battery related downtime - without sacrificing power. Watch and compare it to the competition here.
