What is a Rotary Hammer?

The rotary hammer is a heavy-duty tool designed to carry out works like drilling through or chiseling hard materials. It is often compared to the hammer drill since they are both great for drilling through concrete. However, this type of device is bigger and heavier.

They come with a piston mechanism in place of a special clutch. And thus, they can create deeper drills much faster as the mechanism provides a powerful hammer blow to the back of the bit. Utilizing the “Electro-pneumatic” hammering mechanism, they are able to generate high power. Usually, rotary hammers are electrically powered.

Rotary hammers are almost always used for masonry as it can drilling through concrete walls quickly and efficiently. They can also be used to make dowels. You require a special kind of bit for a rotary hammer as any other bits will not be able to handle the unrelenting force of the machine.

Although rotary hammers are mainly used for construction, masonry, or other heavy works, especially drilling into concrete, their utility is not limited to just that. Other functions of this type of drill include breaking concrete or drilling through bricks or CMU blocks.

This tool is also used in demolition and digging. Even rock climbers find some use out of the rotary hammer; they use it for installing bolt and harnesses. Here are some advantages and disadvantages of using a rotary hammer.

What is a Hammer Drill?

The hammer drill is a very common type of drill and is used by almost every worker. They are powerful drilling instruments, specifically designed to drill through hard surfaces like concrete or masonry. However, that is not their only use. These instruments are really handy and can be made use of by almost every person.

It uses a percussive mechanism. For this very mechanism, the drill performs successive bursts of hammer thrusts to drill through a material. That allows the machine to drill without needing much effort, making it ideal for drilling through concrete or other hard materials. With other types, it would take a lot hassle drilling through them.

Generally, hammer drills are pneumatic instruments. They can also be powered through gasoline or electricity. Gasoline or electrical forms of hammer drills are not very common these days.

A hammer drill is a versatile machine that can serve a lot of purpose besides drilling through concrete. It has a toggle that allows it to alternate between a hammer drill and a screwdriver or a conventional drill. With the flick of the toggle, you can essentially transform it into another tool.

Even though you can use hammer drills for light tasks as opposed to heavy jobs, they aren’t designed for them. These machines are big and heavy, which makes them harder to use for small screwdriver works. Other drills like the impact driver, screwdriver, or a traditional drill, can handle those tasks much better and cleaner than a hammer drill.

These tools can be a little expensive, but they deserve every penny. Hammer drills are very safe options when it comes to drilling through dense surfaces. Because of their utility and versatility, many people consider it as one of their first drivers. Some of its upsides and downsides are highlighted below.
