What Are The Difference Rotary Hammers And Air Hammer?

When it comes to building and construction, the hammer is an important tool. There are different types of hammers, but today we will be focused on two types; the rotary and the air hammers.

Most people often think that these two are the same thing. So what exactly is the difference between rotary hammers and air hammers?

A rotary hammer is a much bigger and heavier tool. It is either powered by batteries or can be corded, meaning it uses direct current power to work. It is usually used in masonry or concrete work because it is fitted with drill bits that are long and heavy, which makes dealing with concrete easy.

An air hammer, on the other hand, is a much smaller tool. It is also lighter and is also known as an air chisel. It comes with an assortment of tools so you can pick one depending on the work you want to do at the time. The air hammer is also connected to an air compressor which is used to power the chisel.

Both these hammers use electricity, and so you will probably need a multimeter. A multimeter is a device that is used to measure electricity by combining different measurements in one unit. It can read the voltage, current, and resistance of the tools you are using. The multimeter will come in handy when it comes to measuring the amount of electricity you are using to know whether you are exceeding the limit or not.

Now since the two hammers, the rotary hammer and the air hammer cause confusion, we will dive into them. First off, we will look at them on their own, and then finally we will compare them against each other to see their differences.

The rotary hammer

As mentioned before, the rotary hammer is a big, bulky tool mostly used in concrete and masonry work. It is used in drilling holes in concrete. The hammer uses a lot of power to make it easy to drill holes in concrete. For it to work, it uses not only the rotating motion but also a push and pull motion to drill. This produces high impact, which causes the holes to be drilled quickly.

The hammer does not spin fast when it comes to RPM. It makes up for its slowness with its impact power. The hammer works well on hard and brittle surfaces like concrete. They are ideal for drilling holes in walls and concrete floors. This is because they use the drills spinning flutes combined with the right bit to pulverize materials and remove dust and debris.

They also have different modes that you can use, e.g., the drill and hammer, drill only or the hammer only mode. It functions like an air hammer when it is on the hammer only mode, which is where the confusion comes from.

The rotary hammer is mostly used for drilling holes in both concrete and wood, demolitions and when placing anchor bolts, pins and dowels in plumbing.

The air hammer

The air hammer is a much smaller, handheld tool. It is used to carve stones, cut or break metal objects. It can accommodate different tools, depending on the task at hand. It works by using air from an air compressor. This air is used to operate a piston which drives the tool shaft.

The air chisel is easy to use due to its size. The small and short-barreled hammer is suitable for light-duty while the longer air chisel is designed for much heavier work. The amount of work you can get out of it will depend on the air compressor. A good, high powered compressor will make work much easier than a weaker compressor.

The rotary hammer is used in work that requires chiseling. Due to their small size, they are perfect for metalworking shops. You can use the air chisel to cut sheet metals, leaving them clean without any burrs. You can also use them to flatten metals or to mold them into specific shapes.

It can accommodate an assortment of tools so that you can use it in metalwork, masonry, woodwork, and even rubber work. Rubber work includes taking apart shock absorber fasteners, rubber brushings when it comes to the garage. You can also use the chisel to scrape off paint, tiles or even excess mortar.

Similarities between the rotary and the air hammer

Though these two tools are clearly different, they have their similarities too. These include the fact that they use impact action. They both put a lot of impact on the surfaces they are working on. They also use oscillating pistons when they are in use. They also direct the force of their impact parallel to the direction of the tool shaft. They both also deliver the blows of their hammers directly on the material they are working on.

Differences between the rotary and air hammer

One of the major differences between the two tools is their size. The rotary hammer is a bulky, heavyweight tool while the air hammer is lightweight and small. It is a handheld tool that is used for much smaller jobs than the rotary hammer.

Another thing that stands out between these two tools is their accessories. The rotary hammer has been fitted with drill bits that is used for drilling. It has three different modes that allow you to either use the hammer only, drill only or hammer and drill mode. On the other hand, the air hammer has a varying assortment of tools that can be exchanged depending on the work at hand.

The last difference comes with how they are powered. The rotary hammer can be corded where it uses direct power from a power source, or it can use batteries and be cordless. The air hammer though uses an air compressor connected to it for it to run.

Those are the few differences we have found between a rotary and air hammer, and we hope you now know the difference.
