DeWalt DCF899B Vs DCF899HB Product Review

Size and Weight 

When looking for an impact wrench, one tends to go for the one that is more compact and much lighter. The smaller and lighter it is, the more work can be done with less fatigue.

DeWalt DCF899B and DCG899HB have the same dimensions, 9.9 x 4.2 x 10.6 inches. It only shows that they are as compact as possible.

However, when it comes to their weight, one is much lighter than the other. DeWalt DCF899B weighs about 6.39 lbs while DeWalt DCF899HB weighs only 5.8 lbs. It only proves that DeWalt DCF899HB can be handled more conveniently when doing overhead works.

Nonetheless, both can be used even in tight workspaces. 

Motor and Battery

Another thing one looks into when choosing an impact wrench is the item’s battery life and overall motor efficiency and performance.

So, to address this, DeWalt launched DCF899B and DCF899HB brushless impact wrenches that are powered with heavy-duty 20V Lithium-ion batteries.

With their 20V Lithium-ion batteries, you will surely be able to do more work and worry less about frequently sitting out because of low battery. Plus, they both use a brushless motor that provides higher work efficiency and better performance. This motor type also protects your hearing by not making earsplitting noise.

Torque and Speed

Of course, the factor that mostly affects the user’s decision-making when it comes to getting his next impact wrench is how powerful the tool is.

DeWalt DCF899B and DCF899HB both have the same torque and speed. They can both deliver a maximum torque of 700 ft-lbs and a breakaway torque of 1,200 ft-lbs.

Both cordless impact wrenches are capable of removing or adjusting bolts and nuts at different speeds. It can complete a task at 2,400 IPM or depending on the user’s preference, one can choose between 0 – 400 / 1,200 / 1,900 RPM. 

Other Features

DeWalt DCF899B and DCF899HB are both under the line of cordless products of the manufacturer, which make them more desirable among users because of their portability.

These power tools also feature a three-speed gear to allow the user maximum control of its speed. Plus, they are both furnished with LED light at the base of their ergonomically textured handles to provide users the opportunity to work on poorly-lit areas. 


As you can see, these DeWalt cordless impact wrenches only differ in the type of anvil used. DeWalt DCF899B has a detent pin anvil while DeWalt DCF899HB has a hog ring anvil.

The anvil of your impact wrench serves two purposes. Its front part is where the bit attaches, and the rear part, which is usually inside the gearcase, is where the hammer strikes the anvil.

The detent pin anvil securely holds the socket, and to release it, one will need a small screwdriver. The hog ring anvil, on the other hand, allows users to put on and pull out impact sockets by hand.

Depending on what you’re working on, you may choose between which anvil type to go for.
