The DEWALT DCD950VX 18-volt cordless hammerdrill/drill/driver is a powerful, super-versatile tool capable of drilling holes and driving screws in virtually any building material you’re likely to encounter: wood, plywood, composites, plastic, metal, steel and even poured concrete, stone and concrete block. It’s driven by a 18-volt XRP extended-run battery, which produces an impressive 450 unit watts out of power. And with three operating speeds (low: 0-500 RPM, medium: 0-1,250 RPM, and high: 0-2,000 RPM) you can work fast and efficiently. When switched to the hammerdrill mode for masonry work, the variable-speed tool combines bit rotation and concussive blows to produce: 0-8,500 blows per minute (BPM) on low, 0-21,250 BPM on medium, and 0-34,000 BPM on high. But wait, there’s more: What sets this DEWALT tool apart from similar models is that it comes with a vehicle battery charger that plugs into a truck or car cigarette lighter or 12-volt accessory outlet. That way, you can keep the tool charged up and ready to work anytime, anywhere, even while driving to the jobsite. Other features include: traditional pistol-grip design; 22 slip-clutch settings for precise screw driving; 360-degree rotating side handle; patented all-metal transmission for smooth operation and improved run time; heavy-duty, -1/2 -inch ratcheting chuck that prevents bits slippage; and a super-bright LED worklight for increased visibility in dark, shadowy spaces. The DCD950VX is an invaluable asset at the jobsite or in the workshop. It comes with two 18-volt XRP NiCad batteries, side handle, one-hour vehicle charger and storage case. It’s backed by DEWALT’s three-year limited warranty, 90-day money-back guarantee, and one-year free service contract.
