What is a Hammer Drill?

Hammer drills are power tools that are used to drill through concrete, stone or the masonry surfaces. They are used to deal with tougher materials and heavy tasks because of their rotary hammer movements. Besides, these drills can keep their RPM low and control the power at the same time, helping you reduce the surface damage and cut through the tough materials perfectly. A lot of hammer drills also come with variable modes, letting you switch between rotary-only mode and hammer-drill mode to navigate between tasks of varying intensities.

Difference Between Hammer Drills and Standard Drills

Though standard and hammer drills may sound the same, some factors differentiate them from each other.  Standard drills are majorly used for DIY and other lighter tasks and drilling needs, whereas the hammer drills are perfect for more complex use cases. Similarly, standard drills perform a single rotary motion, when hammer drills showcase forward and backward motion, making them ideal for piercing through tougher surfaces. 

For example, standard drills would be a great option for assembling furniture, creating holes, or fixing the shelves, as they’re generally lightweight and easy to handle. Having said that, a standard drill may not be sufficient if you plan to work on concrete or stone. A hammer drill would be the best option in such situations, because of its mechanism that creates powerful impacts.

What to Consider Before Buying a Hammer Drill? 

Speed

Speed is an important aspect to examine when planning to buy a hammer drill. In hammer drills, it is calculated by observing how fast the bit rotates and is usually measured in rotations per minute (RPM). Higher speeds are best suited when drilling on materials such as wood and metal, whereas concrete and masonry materials often demand moderate speeds.

Torque

The torque, however, can be defined as the force that a drill can produce. Durable materials often demand a higher torque since they offer greater power and stability. The majority of hammer drills come with an adjustable clutch to help you adjust the torque settings. But when it comes to the torque, manufacturers maintain no consistency, and hence, comparing the torque rating of hammer drills is more difficult. While some utilize inch-pounds to describe torque, others use Newton-meters.

Power

Just like speed, power is an essential factor that decides the effectiveness of a hammer drill. Power indicates how greatly a drill can perform and is usually measured in watts or volts. Heavy-duty operations like drilling into masonry or concrete often require a high-power drill, whereas a drill with less power will be enough if you are working on some lighter materials or simple tasks.

Chuck size and type

The largest drill bit size a hammer drill can accommodate is often determined by its chuck size. Commonly used chuck sizes fall between 1/2 and 3/8 inches. The larger the chuck size, the larger the options you have to use different drill bits suitable for different operations. If you’re planning to use the drill for multiple use cases, it is better to go with a hammer drill with a larger chuck size, as it offers you greater flexibility.

Corded v/s cordless options

Corded or cordless hammer drills? This is another crucial point to consider before buying a hammer drill to ensure you make the right choice. As we all know, hammer drills are available in corded and cordless varieties. If functionality and performance are the usps that you search for than portability, your best choice would be a corded hammer drill. They are often considered perfect for heavy-duty tasks as they offer consistent power flow. However, if you carry your drills often to job sites, it’s better to opt for a cordless drill as they are portable and convenient.

Ergonomics

Ergonomics is a factor that one shouldn’t overlook. You might have to hold the hammer drill for an extended period, sometimes depending on your work. Choosing a highly ergonomic drill helps you stay comfortable for long in such situations. Opt for a drill that’s easy to handle and comfortable to hold. Such drills can help reduce fatigue and improve your work efficiency. Additionally, you should also be mindful of the weight of the drill. Heavy drills may slow down your work at times, while lighter ones help you finish your work faster.

Impact rate

When choosing a hammer drill, impact rate is something that you must not miss. It is often represented in beats per minute (bpm), and indicates how frequently they can deliver strong blows on a material. The higher the bpm, the faster the drilling will be on materials like concrete. For simple, DIY tasks, a moderate bpm would be sufficient.

Auxiliary handles

The auxiliary handle is a part of the drill that not only takes care of your safety but also provides the required grip during the operations. By offering the grip, this handle reduces the risk of injury and improves precision in work. It prevents the drill from going out of control while working and makes it easier to handle the machine by distributing its weight. Hence, always choose a model with auxiliary handles.

Additional features

Though most hammer drills may look the same, some include additional features that distinguish them from others. For extra safety and control during drilling, consider opting for a model with a removable side handle. This allows you to use both hands for drilling and maintain a balance during work. Additionally, you can also look for an auto stop mechanism in the drills, especially when you plan to use them for heavy-duty work. This feature stops the drill automatically when it senses an over-rotation.

Common Applications of a Hammer Drill

Hammer drills can be used to perform a variety of tasks, not just drilling. Below are some other applications of these drills.

• Masonry needs: The right hammer drill can make your masonry work more manageable, whether you use it for installing shelves or for a stone project. These drills make your work smooth by efficiently drilling on machines.
  
  
• Concrete drilling: A hammer drill for concrete is your best option when working on construction tasks. Compared to regular drills, these drills provide more power and efficiency during work. Besides, they can drill quickly in hard surfaces, making them a perfect choice for heavy tasks.
  
  
• Installing tiles: A Hammer drill ensures your tile installation is proper, thanks to its precise operation. They ensure that the holes in the tiles are drilled properly without causing any damage. 
  
  
• Home renovations: Are you a DIY enthusiast? Then, you must have a hammer drill at home or in your workshop. These drills can be handy for a variety of tasks, from assembling furniture to installing fixtures.
  
  
• Plumbing: Be it a plumbing installation or repair work, owning a hammer drill can help you in a great way. These drills not only assist you in drilling through hard materials, but also do so with precision. 
  
  
• Professional construction work: This is one of the most common uses of hammer drills. They are used for drilling hard concrete slabs, inserting bolts, and other similar applications.

Power Recommendations for Various Tasks

The power recommendation for the hammer drills varies depending on the type and the task you intend to undertake. Below are some of the common suggestions. 

For home use: DIYers and occasional users of hammer drills are often recommended to opt for cordless drills with a 600–800 W power. Such models are usually handy and light, making movement easier. Some of them even come with variable speed options and even offer a hammer function, making your DIY work even more manageable. 

For medium tasks: If drilling holes in the masonry or concrete is your work scenario, a model within the watt range of 800–1200 is recommended. They not only drill smoothly through the surfaces, but also have more power. Besides, you may also find models with hammer-only mode as well as speed setting adjustments as additional features.

For heavy tasks: Drilling huge holes through concrete or granite surfaces may not be possible with a moderate power hammer drill. A high power drill with a watt range of 1200 might be needed in such cases. Such models are primarily designed specifically for handling tougher materials and come with advanced features. 

In conclusion, choosing the best hammer drill completely depends on your use case. There are several models available in the market and it is important to be mindful about the power needs as well for a smooth operation. For lighter projects, cordless drill with moderate power would be sufficient, whereas for heavy tasks, you might need a powerful model. You have to also consider factors such as the torque, chuck size, ergonomics, etc. as well before making a final decision.
