DEWALT DCF899B vs DCF899HB Review

If you are in need of a new, electric wrench, you may want to consider adding an impact wrench to your tool set. Impact wrenches are great for delivering high torque for difficult bolts, with little effort needed form the user. Dewalt makes two very similar high torque impact wrenches, but they have a few different features that you should know about before purchase. Let’s take a look at these two products, and see which one would be the best fit for your unique, electric wrench needs!

Dewalt DCF899B Impact Wrench


The Dewalt DCF899B impact wrench comes with a brushless motor to allow the product to work efficiently for longer periods of time. This product is heavy-duty, with a maximum torque of 700 feet / pounds. With a breakaway torque of 1,200 feet / pounds, this product has a lot of power.

For your convenience, a three-speed selector switch also comes with this product, so you have more control over your project. This is accompanied by an L.E.D. work light, so you can keep working no matter how dark or light the area is. This L.E.D. has a 20-second delay, to provide added visibility in dark places. With a battery fuel gauge, you can easily keep an eye on the amount of battery you have left and adjust accordingly.

This product does not come with a battery and charger, so these items will have to be purchased separately before use. The Dewalt DCF899B comes with a detent anvil, and is ½ inch in length. This product also comes with a comfortable grip to make working for long periods easier.

The Dewalt DCF899B has a lightweight and slim design, so you can easily reach into tighter spaces and continue working with ease. Despite its slim design, this wrench can withstand a 6 to 8 foot drop. The anvil is also resistant to breaking or shearing. For added convenience, the detent pin helps prevent dropping sockets by having strong socket retention.

Dewalt DCF899HB Impact Wrench


The Dewalt DCF899HB impact wrench is very similar to the previous product. This product also has a brushless motor for durability, and is made to withstand heavy-duty projects. With a maximum torque of 700 feet / pounds, and a breakaway torque of 1,200 feet / pounds, this product has a great deal of power.

This product also comes with a three-speed selector switch, allowing you to have great control while working. An L.E.D. work light is also included, with a 20-second delay for added visibility. Similar to the last product, the battery and charger do not come with this product and must be bought separately.

The Dewalt DCF899HB comes with a hog ring anvil, and has a ½-inch wrench size. The hog ring anvil makes socket changes easier if you have to switch sizes often. It doesn’t have maximum retention, making these switches smoother.

This product is designed lightweight, but it can handle a 6-8 foot drop. This product is also created with a durable coating, to withstand grease, cleaners, and chemicals—adding longevity to the product. The Dewalt DCF899HB fits into tight spaces, much like the previous product, for easy use wherever you may need it.

Both of these impact wrenches are designed to be durable, lightweight, and deliver excellent results for long periods of time. If you need a lighter-weight wrench with a detent anvil that is resistant to breakage and grips your sockets, then the Dewalt DCF899B may be the best choice for you. If you would prefer a wrench with a durable coating, and need a hog ring anvil to move quickly from socket to socket, the Dewalt DCF899HB is probably a better choice for your needs. Both of these products come with L.E.D. lights, cordless design, and heavy-duty durability. Neither of these products come with a battery pack or charger. With all this in mind, either impact wrench is a great choice for your work or personal project needs.
