What’s the Difference Between a Hammer Drill and a Rotary Hammer Drill

From the terms themselves, it’s pretty understandable why people tend to be confused about these two tools. In one aspect, yes, they are the same – both are great tools for drilling masonry because they can produce a pounding force.

Yet, with their design and build, it’s actually pretty easy to identify one from the other. Hammer drills are more compact and lightweight; they look very similar to drill drivers. Rotary hammers, on the other hand, are typically longer and heavier that’s why they usually come with a 360-degree side handle for better control.

Moreover, when it comes to performance, rotary hammers are also more powerful. They offer a hammer-only mode, and usually come with an SDS chuck for better hammering.

In terms of internal mechanism, a hammer drill contains two discs with ridges similar to that of a poker chip. As one disc slides past the other, it rises and falls that causes the chuck to slam forward and back. Separating the discs is a clutch that stops the pounding action of the hammer drill.

In contrast, a rotary hammer is built with a piston that’s driven by a crankshaft. The said piston is the one that produces the pounding action of the rotary hammer. The piston rides in a cylinder thereby creating air pressure when it is being driven forward. Then, the created air pressure drives the hammer mechanism.

Rotary hammers are also generally preferred by professionals and intended for heavy-duty tasks because they produce more impact energy compared to hammer drills. Also, rotary hammers typically offer 3 different modes to choose from: drill mode, hammer drill, and hammer mode.

When it comes to bits and attachments, you don’t need to worry about needing to invest much for a hammer drill since it is intended for light masonry applications only.

For rotary hammers, on the other hand, an SDS chuck is usually included. Another common attachment is the SDS-plus and the SDS-max.

Other attachments available for rotary hammer is the clay spade, cold chisel, tile remover, bull point chisel, and scaling chisel. Each one is for a different purpose than the other so you need to study each one before buying to make sure that you have the right attachment for your task.

DeWalt DCD985B vs DeWalt D25263K

As mentioned above, DCD985B is a hammer drill while the D25263K is a rotary hammer. The first one’s a 20V cordless tool, while the latter is a 115V corded one. Nonetheless, both were built to be sturdy, durable, and to provide as much comfort to its user as possible.

As mentioned, the DCD985B hammer drill expectedly produces less power compared to the D25263K rotary hammer. The DCD985B is still for light masonry tasks while the D25263K can handle the heavy applications. Another difference is that the DCD985B is built with a 3-speed all-metal transmission from which you can control the tool’s speed; while the D25263K has a large variable speed trigger.
