The Bosch GNB18V-12 PROFACTOR 18V Concrete Nailer runs on the PROFACTOR System, delivering the power needed for tackling heavy-duty interior steel framing or commercial drywalling jobs. The nailer has the capacity to sink up to 1.5 in. collated concrete nails into concrete. It is part of the PROFACTOR System, which pairs BITURBO Brushless Technology with a CORE18V High Power Battery. BITURBO Brushless Technology is a high-performance motor and drive-train system designed to deliver power comparable to high-demand corded tools. Using a single CORE18V battery, this cordless nailer is an ideal replacement for gas-powered concrete nailers, because it eliminates the need for consumable gas cartridges. It includes an air-spring design, which provides fast, consistent nailing. It comes with a 22-shot collated magazine (an extra-capacity magazine, which can hold up to 44 collated nails, is sold separately), and a single-shot magazine and nosepiece. This nailer features an open system, allowing for competitive collated nails and single shots to be used. In addition, Bosch will supply an array of branded nails ranging 5/8 In. to 1-1/2 In. for concrete, and 1/2 In. to 3/4 In. for steel applications. It has an easy-to-use depth adjustment into the workpiece, and it has an on-tool user display, which helps manage tool performance, troubleshooting and battery life status. The CORE18V 8 Ah High Power Battery is compatible with Bosch 18V tools, is optimized for PROFACTOR tools and delivers 2x more runtime than the CORE18V GBA18V40 Advanced Power Battery. This is a renewed product backed by a 90-day warranty.
