Performance

The Dewalt DCF899HN-XJ impact wrench is an extremely powerful tool that delivers up to 950 Nm of max torque and 700 ft-lbs of nut-busting torque. It utilizes Dewalt's efficient brushless motor that provides superior runtime and durability compared to brushed motors.

The impact mechanism generates 0-2100 impacts per minute, allowing you to drive fasteners quickly. Speed settings let you dial in the precise amount of power needed for the task. There are 3 speed/torque settings - 0-400 rpm/950 Nm, 0-1200 rpm/710 Nm, 0-2100 rpm/400 Nm. So you get the ideal balance of power and speed.

Despite the high power output, the DCF899 still provides excellent runtime thanks to the efficient brushless motor and large 5.0Ah battery. On a full charge you can expect up to 90 bolts per charge on the highest setting. The battery also has Dewalt's Fuel Gauge which displays remaining runtime.

Overall, the performance is best-in-class with professional power, speed, and runtime suitable for automotive, construction, and industrial applications. The variable speed settings give you precise control over the power delivery.

If you need a more compact impact wrench, check out the DeWalt DCF880N-XJ. This model measures just 3.94 cm x 9.61 cm x 6.3 cm, making it easy to fit in tight spaces. It delivers up to 339 Nm of max torque, which is suitable for most automotive and light construction jobs. The brushless motor provides excellent efficiency and runtime.

So if you need maximum power, the DCF899 is the way to go. But if you prioritize compact size for tight work areas, check out the DCF880N-XJ. Both utilize Dewalt's latest brushless motor technology to provide pro-level power along with extended runtime per charge.

When it comes to driving and removing fasteners, few tools can match the performance of these Dewalt impact wrenches. They combine several key features that pros demand - high torque output, variable speed control, efficient brushless motors, and long runtime. Whether you need to power through rusted bolts or precisely drive hardware, the DCF899 and DCF880N-XJ have you covered.

Design

The DeWalt DCF899HN-XJ impact wrench features an ergonomic and compact design that makes it easy to handle and maneuver. Despite its power, the tool feels well-balanced in hand thanks to its 5.70 lb weight and 9.53 cm height.

The rubber overmold grip gives you a comfortable, non-slip hold of the tool. This is important when using an impact wrench, as you need a solid grip to counteract the torque reaction forces. The grip fits nicely in your palm and allows you to hold the wrench steady.

The short length and slim body profile lets you work in tight spaces where a bulkier tool wouldn't fit. You can get the DeWalt wrench into small engine compartments, behind equipment, and other constricted areas. The compact head design also gives you good visibility of what you're working on.

Overall, the ergonomic shaping and grip make the DCF899HN-XJ comfortable to hold through extended use. The balance and handling allow you precise control as you power through tough bolts.
