SENCO says their new line of Fusion finish nailers, currently including 15- (FN65DA) and 18-gauge (FN55AX) models, combines the best of air and cordless technologies. Powered by an 18-volt Lithium-Ion Phosphate battery, the nailers can reach an 80 percent charge in 15 minutes. Between charges, in part due to the patented Reflex Shot design, the nailer can deliver up to 500 drives. It also provides an instant trigger response, with users choosing between sequential or contact activation depending on the job. “The air pressure is preset at the factory, permanently sealed and never needs recharging,” says product manager Joe Knueven. The depth of drive is adjustable tool-free on the 1/4" aluminum drive cylinder, which weighs in at six pounds. A nose-mounted LED surface light lets you see what you’re doing, while the EZClear removable magazine simplifies fastener removal. 2010 suggested pricing is $440 for the 15-gauge and $399 for the 18-gauge nailer.
