Because it uses a 1/4-inch hex drive, the DC668KA easily handles the majority of fastening accessories, from screwdriver bits to nut runners. This versatile tool features a robust motor that won't overheat, thanks to the fan, and replaceable brushes. There's also a Versa-Clutch torque adjustment dial for straightforward set-and-go operation and protection against stripping and breaking. And dual speeds run either 0-900 or 0-2,700 RPM for precise results no matter what material your job requires. The DC668KA comes with two XRP 18-volt batteries, one-hour charger, no.2 Phillips bit, 5/16-inch nut runner, and a kit box.
From the Manufacturer
The DEWALT DC668KA is an industrial-grade cordless screwdriver that’s specifically designed to meet the demands of professional metalworkers, steel-frame carpenters, metal fabricators, and HVAC contractors. The ruggedly built tool is driven by an 18-volt XRP extended-run battery, which powers a two-speed, fan-cooled high-performance motor. The ability to choose between low speed (0-900 RPM) and high speed (0-2,700 RPM) provides superior screw-driving control in a wide variety of material thickness. And, the -1/4 -inch hex-drive screwdriver is equipped with DEWALT’s Vera-Clutch torque adjustment that lets you “dial in” the proper torque needed to efficiently drive virtually any fastener, without fear of stripping or snapping the screw. From framing steel-stud walls, to building and installing ductwork, the DC668KA can drive screws through cold-rolled steel ranging in thickness from 28 to 12 gauge. (It’s not intended for use with "red iron" or structural steel.) The DEWALT DC668KA 18-Volt Cordless Light-Gauge Steel Framing Screwdriver comes with two 18-volt XRP batteries, one-hour charger, No. 2 Phillips bit, 5/16 -inch nut runner, and storage case. It’s backed by DEWALT’s three-year limited warranty, 30-day money-back guarantee, and one-year free service contract.
