The detent anvil mechanism is easy to maintain, requiring a rather simple procedure to inspect and repair when needed. The last difference between these two products is the maintenance and repair procedures. 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 hog ring anvil results in a slight weight increase for the DCF889HB.

This makes it convenient to use this in overhead applications for longer periods of time without straining the arms much. The DCF889B is slightly lighter at 5.8 lbs. This difference in mechanism also leads to a slight difference in weight between these two models. This model of impact wrenches is preferred by automobile mechanics and can be seen commonly on race tracks while quickly changing tires.

These types of anvils are preferred by mechanics who require speed over the retaining socket.Īs a result, they are operated lower to the ground to minimize the damage caused by the falling socket. The Dewalt DCF889HB on the other hand has a hog ring anvil. This type of mechanism is therefore preferred by those working at heights, such as in construction and elevated assemblies. As a result, this is preferred in situations where a falling socket may cause potential damage to persons working below. The Dewalt DCF889B has a detent anvil, which uses a detent pin to hold the socket to the anvil after removal. It is responsible for the transfer of torque from the impact of the rotating hammer to the socket.Īs 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 main difference between the DCF899HB and the DCF899B, both manufactured by Dewalt, is the anvil mechanism. Differences between Dewalt DCF899HB and DCF899B I was interested to know more about the differences between the two from a technical standpoint, which I have highlighted in the next section. This made me wonder what the difference between the two was.Īs suggested by the name, the DCF899HB stands for a hog ring anvil model, while the DC899B was the conventional detent anvil. That is when I came across the DCF899B and DCF899HB.Īt first glance, they looked alike but had a small difference in price. This was one of the main reasons that motivated me to look for Dewalt products in the impact wrench segment. 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. Dewalt DCF899HB vs DCF899Bĭewalt is one of the most well-known brands when it comes to power tools. While giving you my personal opinion about these two products, I will also list out the various features as well as the pros and cons in brief.Īt the end of this article, I am sure that you will have all the information you need to make a wise purchase when it comes to picking your first or next impact wrench.ĭisclosure: Some of the links below may be affiliate links. Read on as I then review these two impact wrenches individually. Being manufactured by Dewalt, I will also discuss the similarities between the two, including the technology and dimensions. In this article, I am going to discuss the differences between these two models in detail. This is an updated model of the DCF889B, which has a hog ring anvil and is the lighter model of the two.

The Dewalt DCF889B has a detent anvil and is slightly heavier than the Dewalt DCF889HB. Here is the quick answer for DCF899HB vs DCF899B comparison. I was then confused as to what the differences between these two models were. While doing my research, I zeroed down to the Dewalt DCF889B and DCF889HB. Recently, I wanted to change my impact wrench which had aged considerably. As someone who makes my living with power tools, I know just how important an impact wrench is.
