The DEWALT DCN681 Cordless XR Brushless Stapler has a compact, lightweight design that is easy and comfortable to use but durable enough for a worksite environment. It is fitted with a brushless motor for optimum runtime and performance. Uses mechanical rather than gas operation for low running costs and consistent performance, even at low temperatures. Sequential mode allows for precision placement and the bump operating mode provides the user with production speed of up to 4 nails per second. The depth of drive can be easily adjusted using the thumb wheel depth adjuster.
