Screwing plywood and gypsum sheathing to metal studs is time-consuming and tedious. The SF150C pneumatic coil nailer is designed to speed up that work. It drives 1- to 1 1/2-inch ballistic-point helix-shank fasteners that penetrate and hold in 16- to 20-gauge metal studs. The large bugle heads won’t cut into gypsum sheathing. The tool has adjustable depth-of-drive, dry-fire lockout, and a rafter hook. Price: $399. COO: Taiwan. 800-343-9329.
