Dewalt DCF899HB vs DCF899B
Dewalt is one of the most well-known brands when it comes to power tools. Over the years, they have been at the forefront of development and innovation in the field, helping make these tools more efficient and user-friendly.
This was one of the main reasons that motivated me to look for Dewalt products in the impact wrench segment. That is when I came across the DCF899B and DCF899HB.
At first glance, they looked alike but had a small difference in price. This made me wonder what the difference between the two was.
As suggested by the name, the DCF899HB stands for a hog ring anvil model, while the DC899B was the conventional detent anvil.
I was interested to know more about the differences between the two from a technical standpoint, which I have highlighted in the next section.
Differences between Dewalt DCF899HB and DCF899B
The main difference between the DCF899HB and the DCF899B, both manufactured by Dewalt, is the anvil mechanism.
It is responsible for the transfer of torque from the impact of the rotating hammer to the socket.
As a result, it produces high amounts of turning torque in a short burst of time, allowing for forces greater than humanly possible to be applied onto nuts and bolts.
The Dewalt DCF889B has a detent anvil, which uses a detent pin to hold the socket to the anvil after removal. As a result, this is preferred in situations where a falling socket may cause potential damage to persons working below.
This type of mechanism is therefore preferred by those working at heights, such as in construction and elevated assemblies.
The Dewalt DCF889HB on the other hand has a hog ring anvil. These types of anvils are preferred by mechanics who require speed over the retaining socket.
As a result, they are operated lower to the ground to minimize the damage caused by the falling socket.
This model of impact wrenches is preferred by automobile mechanics and can be seen commonly on race tracks while quickly changing tires.
This difference in mechanism also leads to a slight difference in weight between these two models. The DCF889B is slightly lighter at 5.8 lbs. This makes it convenient to use this in overhead applications for longer periods of time without straining the arms much.
The hog ring anvil results in a slight weight increase for the DCF889HB. Weighing around 6.4 lbs, it allows for a more stable operation for longer periods of time, while helping minimize the vibrations of operating this tool.
The last difference between these two products is the maintenance and repair procedures. The detent anvil mechanism is easy to maintain, requiring a rather simple procedure to inspect and repair when needed.
On the other hand, the hog ring anvil requires a couple of basic tools like hammers and screwdrivers, which makes the process of repair and maintenance a slightly more cumbersome one.
Similarities between Dewalt DCF899HB and DCF899B
The Dewalt DCF899B and DCF899HB both have the same dimensions of 9.94” x 4.25” x 10.73”. This combines well with the oversized grips that give the users a comfortable and large gripping surface. This helps use the product for longer periods of time as a result.
Coming to the performance aspect of both these models, they both have brushless motors that offer the same amount of torque and output figures.
They also come with the three speed control setting that allows you to choose the exact speed that you require to get the job done.
Coming to the features that these products share, they both have a battery indicator that allows you to check how much battery is left from time to time. This can be crucial in situations where you do not have regular access to power.
Both these models also have an LED light that allows you to work in low light conditions. This allows you to sight your workpiece quite effectively, allowing you to get the job done much more effectively.
The DCF899B and DCF899HB are both compatible with the 20V MAX battery range from Dewalt.
This gives customers with existing Dewalt products a wide variety of batteries to choose from. With stellar performance and long life being trademarks of this battery range, it gives users the confidence to utilize this tool for long hours at a stretch.
