The BOSCH GNB18V-12K14 18V concrete nailer is Bosch’s entry into the direct fastening market.  The tool is designed to fasten to concrete and steel using an air spring design.  Battery concrete nailers are somewhat new.  Hilit was one of the first followed by DeWalt and now Bosch.  Battery powered concrete nailers require no fuel cell or powder charges so there are instances where this will be the tool of choice.

The BOSCH GNB18V tool weighs in at 9 pounds and is just under 16” long and about 5-1/2” wide. The included magazine can handle up to 22 nails in lengths from ½” up to 1-1/2”. An optional 44 nail magazine is available for the tool. One thing unique to the Bosch battery concrete nailer is that you can take off the magazine and shoot single shot nails that you would typically shoot in powder actuated tools. Think of ceiling clips, EMT clips, studs and more. The tool uses an 18V lithium battery. Any of the current Bosch 18v batteries will slip into the concrete nailer but an 8.0 mah is recommended and included in the kit. Smaller mah batteries will run the tool and you will save weight but sacrifice run time. Bosch has nails for both concrete and steel applications. The NB series is for concrete and the NM series is for metal and are packed in boxes of 1,000.

The Bosch battery nailer, part #GNB18V-12K14 is comes with the tool, 22 nail magazine, single shot nosepiece, 8.0 mah 18V lithium battery, charger, utility hook and case.  If you already have a collection of Bosch 18V batteries and chargers, you can buy the tool bare, part #GNB18V-12N.  The bare tool does not include the battery, charger or case.
