There are many reasons why an Impact Wrench is a practical tool to own. An impact wrench can help you loosen the lug nuts on your car tires if you need to change a flat. It can also come in handy if you need to remove nuts and bolts that have been factory installed or tightened. You might even find it very handy if you are building big carpentry projects such as a deck or gazebo.
Dewalt Impact wrenches are very handy to have if you are tired of using regular wrenches. Hand wrenches can be tiring to use and not tighten as securely as an impact wrench. Because the Dewalt Impact Wrenches are cordless. You will not have to drag around air compressors or extension cords when working on a project.
Dewalt makes two different styles of Impact Wrench. They are the DCF894B, which has a detent pin anvil and the DCF894HB, which has a hog ring anvil. The two cordless impact wrenches are pretty similar in every area except for the pin.
I. What’s the difference between a detent pin anvil (Dewalt DCF894B) and a hog ring anvil (Dewalt DCF894HB)?
The difference between the two types of pins is pretty simple. It has to do with how the socket is attached to the wrench.
The Detent Pin Anvil (Dewalt DCF894B)
Some people feel that the detent pin anvil is a more secure method of attaching the socket to the impact wrench. A detent pin anvil uses spring loaded ball bearings to keep the socket attached. This is a more secure way of keeping the socket attached, but it can be harder to remove it. This can be cumbersome if you are doing a job that requires multiple sizes of sockets.
The Hog Ring Anvil (Dewalt DCF894HB)
The Hog Ring Anvil uses a steel ring in the groove to fit the socket on o the wrench. It can be trickier to get the socket attached, but generally, they can be released easier. So, if you are doing a project with multiple size sockets needed, the hog ring anvil would be a good choice.
Now that we understand the difference between the two types of anvils, let’s take a look at the Dewalt dcf894b Cordless Impact Wrench with a detent pin anvil and the Dewalt dcf894hb Cordless Impact Wrench with a hog pin anvil.
