The piston rides in a cylinder and creates air pressure when driven forward, and it’s the air pressure that actually drives the hammer mechanism. In a rotary hammer, a cylinder of air is compressed by a piston driven by a crankshaft, which in turn pounds the bit.
While both tools move the bit back and forth while it spins, the two have different mechanisms for achieving this. Now, let’s take a look at some of the main differences between the two tools. That mainly applies to materials that need “breaking” like concrete, bricks, etc. This rotary mechanism makes this type of tool much more efficient at creating holes than a normal hammer drill. Rotary hammer drills are hammer drills that use a piston and a rod to hit against the drill bit, which amplifies the effect of the power and therefore makes rotary hammer drills more powerful than their regular counterparts.

The tool is not designed for driving screws in (although it can do so) like an impact driver is, but for producing a hole much faster than a conventional drill. It can deliver thousands of blows per minute (BPM), helping the drill bit cut through extremely tough materials like concrete, stone or brick. What Is a Hammer Drill?Ī hammer drill is a drill that is specially designed to not only spin the drill bit, but to also punch it in and out. Hammer Drills and Rotary Hammers: The Basicsīefore trying to figure out which of the two tools is the right one for your job, let’s start with the basics – by looking at what each of the tools is. Continue reading to learn what the differences between the two are and which one will work better for the job that you need to get done. When it comes to working with concrete and other harder materials, the two most common types of drills are hammer drills and rotary hammers. The reality, though, is that just like there are various types of cars and other everyday products, there are also various types of drills.
