DEWALT DCF899B 20V MAX XR Brushless High Torque 1/2″ Impact Wrench Review
When it comes to the world of power tools, a formidable manufacturer is none other than DeWalt. But, does this DeWalt DCF899B Brushless Impact Wrench deliver the power you should expect from such a world-renown company?
We have reviewed the unit, and it comes as a bare tool, meaning that it does not come with a battery or charger, a common feature in power tools from the manufacturer with model numbers ending in letter “B.” It features a heavy-duty impact mechanism capable of handling a max torque of up to 700 ft-lbs and a maximum breakaway torque of 1,200 ft-lbs.
The impact wrench has a 3-speed selector switch for controlling drive/torque depending on your application. A bright LED light is also added to enable you to work in low light situations.
This DeWalt impact wrench model is a very well balanced and ergonomically designed unit. So, what are the features that we fell in love with in this unit?
An Anvil For Your Jobs
DeWalt offers us this mode with a detent pin. The detent pin anvil contains a retaining pin that you must press to release any socket from the impact driver.
The detent pin is perfect for those people who intend to work in elevated positions and will be driving nuts or bolts of the same size. This is a common feature in construction type projects such as building or bridge assembly and water tower assembly, where a detent pin prevents the socket from unexpectedly falling out.
At 6.6 pounds without the battery fitted, the first thing you will feel when you pick up this DeWalt tool is its compact assembly and balanced motor. However, it is not the lightest of compact drills.
The manufacturer has made a conscious effort to build this Brushless Impact Wrench into a small package that gives you pure power. Within a few minutes of powering up this unit and using it around your shop, it will be clear that DeWalt has indeed stepped up the bar when it comes to power.
The maximum tightening torque of 700 ft per lb and breakaway torque of 1,200 ft per lb are the numbers you should expect from a 3/4-inch impact wrench. At this power, expect to use the 3-speed selector quite often.
At level one, you get a slow 400 Revolutions per Minute (RPM) that’s nicely delivered for putting lug nuts back on vehicles in a manner that you are in control. Without using the hammering, you can center the wheel and tighten just enough to put a bit of pressure on a tire as you finish off installation with a torque wrench.
DeWalt has gone the extra mile to infuse a very solid feel into just about all their power tools. The rubber over mold feature on this model is a familiar sight that you would expect in many DeWalt drills.
A variable speed trigger on the impact driver is easy to control and precise, even at level three for your impacting applications – it is also easy to adjust, even when you are wearing heavy gloves. However, the LED is bright, maybe too bright especially if you are working on polished chrome or aluminum. Nevertheless, the placement is great since larger sockets are likely to block out light if it was placed any higher or closer to the anvil.
The LED work light is automatically triggered once you depress the trigger switch, and turns off 20 seconds after you release the trigger switch. If you continue pressing the trigger, the light remains on.
When you include a 5.0 Ah battery with this impact wrench, the runtime you get is of a professional grade. The combination of a high-capacity battery and the brushless motor offers you a machine that can efficiently run an entire day removing or tightening bolts
The power feels consistent even as the battery drains down. At 33 percent battery life, the impact wrench feels just as powerful as it was when fully charged.
Forward and Reverse Button
The tool features a forward/reverse control button for changing the direction as well as a lock-off function. The center of the button turns the tool off, and you need to ensure that the trigger is released when changing the control button position.
Who can use it? If you are looking for a professional, hardwearing tool, you cannot go wrong with this DeWalt impact wrench model. It is designed to make an easy task of your toughest job with the 3-speed setting offering you full control over your applications. You get more power when you require it, and more control once you turn it down.
DeWalt DCF899B: Final Word
The DeWalt DCF899B Brushless Impact Wrench features a pin detent and not a hog ring drive. What you prefer is a matter of personal opinion, but it is worth remembering that while ordering the unit. Users love its power, and many find it easy to use and really fast. It is a little on the heavy side, but that is expected when you are working with a high-powered impact drill like this.
