The 10 Best Rotary Hammer Drills For Heavy Duty

Here you can find out the top-notch rotary hammer drills for construction, DIY, or remodeling works.

Rotary hammer drills are high-performance power tools that use rotary mechanism and electric power to easily drill through diverse tough materials like drywall, concrete, stone, tiles, or bricks. They are quite useful while dealing with medium to heavy-duty projects.

Also, it can be turned to a compact demolition hammer (SDS hammer) by flipping a lever while dealing with demolition work, basement renovation or framing projects.

They are available in different shapes and sizes that differ from each other in terms of features and are used to do various heavy-duty tasks. This makes it a bit difficult to choose your right option.

Here is a quick look at key factors to consider before investing in rotary hammer drills.

• Type: Corded and cordless are two types of rotary hammer drills based on their power source. Each type has its own set of pros and cons. Corded models run by consuming power from a wall outlet and a powerful option that is used to drill thick concrete and masonry. Need to buy an extension cord to work at far distances. Cordless models run on battery, which is best to use for offsite and outdoor drilling. It is portable yet has limited runtime. Need to buy extra batteries for long time use.
• Power: Corded rotary hammer drills are measured by amps used by the motor from the outlet to run the tool. This rating will range from 8 – 15 amps, in which models with 13 or 14 amps are considered powerful. Cordless drills run on a battery, which is rated by voltage, and its range will be 18 – 36 volts. Also, consider the amp-hour of a battery to enhance its runtimes.
• Speed: Speed regulates the motor’s performance, and it is determined by the rotation and impact speed. Here the rotational speed is measured in RPM that ranges from 230 – 2300 RPMs, while impact speed is measured in BPM (blows per minute) that ranges from 2150 – 5800 BPM. Select a hammer drill with 1000 – 1500 RPMs and 4000 – 4500 BPMs for regular household usage.

To help you differentiate your best option, we came up with a list of some Best Rotary Hammer Drills (with description, best features, pros, and cons) along with a detailed “Buying Guide”. Read on to know how to pick your correct model as per your requirement.

Buying Guide for the Best Rotary Hammer Drill

It is a tough job to drill holes through hard materials in the masonry profession. There are several factors to consider while shopping for the rotary hammer drill. Here, we are providing a list of some key factors to seek out when choosing the best option, as per your requirements.

Let’s get into its details.

1. Types (Corded Vs. Cordless)

Based on their power source, corded and cordless are two types of rotary hammer drills. Both are electric-powered drills, in which corded runs when plugged in the wall outlet, whereas cordless runs with battery power. Though they exhibit similar functioning, yet you have to choose the right one based on your intended task and requirement.

• Corded : With their continuous power supply, these corded rotary hammer drills work well on hard projects like thick concrete and masonry. It is a powerful tool that has to be used indoors or in areas with a nearby power outlet. Also, a heavy-duty extension cord is required for operating far distances. You should be aware of its cord position, which affects the user’s concentration, and thereby the work.

• Cordless: With their portability and ease of use, these cordless rotary hammer drills are ideal to work for offsite and outdoor drilling needs. It runs with a lithium-ion rechargeable battery that makes it powerful, and strong. You have to wait for a few hours to recharge the battery or else invest in another battery to use it continuously. These models are a bit more expensive than their corded counterparts.

2. Power

As we already mentioned, corded (runs by electric-outlet) and cordless (battery-operated) are two power sources available to run these drills.

• Corded : The power of these tools is rated by the amperage (amps) used by the motor from a standard outlet. The power rating range of these rotary hammer drills will be 8 – 15 amps. The models with 13 or 14 amps are considered the best and powerful options. Most manufacturers allow a border to diminish the chances of tripping a breaker, even when there is a power surge.
• Cordless: The power of these tools is rated by voltage (volts, V), and it will range from 18 – 26 volts. This rating indicates the maximum available power, which means it is essential to check the amp-hours (Ah) of its battery (lithium-ion and Ni-cad). For instance, you can run a battery with a 4.0Ah twice as 2.0Ah battery. However, this Ah difference won’t have an impact on DIYers, yet professionals want to use the highest possible Ah batteries to maximize runtimes. Here lithium-ion batteries are the best to provide a stable power source that recharges quickly and is eco-friendly.

3. Speed (RPM and BPM)

The performance of the rotary hammer drill is determined by its speed, and it is measured in blows. Rather than a special clutch, these rotary hammers use a piston mechanism that delivers a powerful hammer blow. Measure the blows in joules (J) and blows per minute (BPM) is used to measure the speed of the blows. The rotary hammer with higher joules and higher blows per minute (BPM) will easily and effectively drill through masonry.

Impact speed and rotation speed are used to measure the translational and rotational movements made by the hammer at a particular time. Here the rotational speed of the hammer is measured in rotations per minute (RPM), which ranges from 230 – 2300 RPMs. While impact frequency will range between 2150 – 5800 BPM. If you are looking for a hammer for regular household usage, then prefer to purchase a rotary hammer drill with speed levels of 1000 – 1500 RPM and 4000 – 4500 BPM.

4. Operation Modes

Rotary hammer drills are versatile and offer 2 – 3 operating modes. A rotary hammer with two modes is quite commonly found in most hammers, as they perform two functions as rotary drilling and hammer drilling, which are small in size and make it a perfect option for metal or woodworking projects.

While hammer with three modes are heavier and perform three functions – rotary drilling, hammer drilling, and chiseling. These hammers offer chisels of different widths, which makes them useful for a variety of projects. For instance, narrow and pointed chisels are used for demolition tasks, while broad chisels make shorter tasks (like removing tiles). Multi-functional hammers feature a switch that allows the user to choose the required mode as per their requirement.

5. Chuck

Almost all rotary hammer drills use an SDS chuck, which won’t close and open as a standard three-jaw chuck. Instead, have a sliding sleeve and mechanism to clamp onto slots in the chisel or drill bit. Thus, it is considered a positive locking method that prevents slipping of the bit.

Usually, these chucks are available in two sizes – SDS and SDS-Plus (with 10 mm shank), SDS-Max (with 18mm shank). SDS bits fit properly in SDS-plus tools, whereas it won’t fit SDS Max or inversely. So, it is essential to purchase the right size bits that suit perfectly for your tool.

A spline chuck is the best alternative, in which bits come with splines to lock them in their place instead of slots. However, the usage of spline chucks is quite less common why because the bits won’t be interchangeable with SDS.

6. Design and Ergonomics

Even though a rotary hammer drill is a bulky tool, yet it is ergonomically designed to make it well-balanced and comfortable to use. Its handles are open, and have a large trigger that makes it easy to use with gloved hands. Also, its rubberized areas offer a secure grip and thereby maximize comfort.

It has an auxiliary handle with 360° rotation at the front part, which allows the user to move and adjust the tool till you find a proper balance and support to work effectively. This extra handle will control a lot of torque generated while using a rotary hammer. Without the proper use of this handle, you might be at risk of getting a wrist injury.

Also, with their powerful hammer action, these tools will vibrate a lot and thereby make the user quickly get tired. So, a few manufacturers designed their tools with vibration control, which acts as a shock absorber between the handle and main body of the tool.

7. Accessories and Attachments

A variety of SDS drills and chisels are the key accessories for these rotary hammer drills. Usually, some of these can be included with the tools pack or purchased separately. Most models feature a handy depth gauge to make it used for proper drilling.

A lot of dust is generated while using rotary hammer drills, which might cause lung or kidney problems. So, it is a must to wear respiratory protection (like a mask) when operating a rotary hammer drill, even some models incorporate dust ports to use them in combination with other extraction tools. It depends on the personal preference of the DIY user, while the occupational safety and health administration (OSHA) has set rules stating that it is a must for professionals to wear a mask, regarding workplace exposure to protect their health.

Most manufacturers offer not just a bare tool (drill itself), but more than it. Some models come in a kit having extra features as a depth gauge, LED lights, handy carrying case, chargers, or additional batteries to make your work effortless. For instance, LED lights will help you to work in low-light areas.

8. Torque or Twisting Power

It is vital to consider the torque rating before buying a rotary hammer drill, why because a model with a high torque rating will offer great twisting actions and thereby enhance the drill performance. So, the torque rating of a drill will decide its twisting power, which is essential for a hammer drill.

9. User-Friendly Features

Apart from the power and performance, you have to check how comfortable and easy it is to operate the drill before making its purchase. Since it is a heavier power tool, it is quite common to have several kickbacks and vibrations. So, purchase a model with a lot of user-friendly features.

• Handle Grip: Choose a model with a soft and comfortable to hold handle grip. For this, visit any hardware store or local power tool dealer to check several drill models and pick the one that fits perfectly in your hands. Most drills offer anti-vibration technology to make the handle easily absorb most vibrations.
• Trigger: Having proper control over the trigger is crucial while operating the rotary hammer drill. So, check whether your index finger will fit comfortably around the trigger or not before buying the drill. It is particularly useful while drilling into concrete or other tough surfaces.

10. Versatility

A versatile tool will allow you to do several tasks easily. For instance, a hammer with variable speeds offers higher productivity. While a drill with a speed control lock will increase safety by locking the operating speed level. Also, the usage of a cordless compact hammer will provide easy access to tight spaces and thereby accomplish multiple bit angles.

11. Price

The price of rotary hammer drills will range from $100 – $250 (or more). If you want to use the hammer for light masonry or drill into thin concrete, then prefer to choose models that come within the $150 – $250 range. They have less powerful motors that run on 7 – 10 amps. If you want to use the tool for a longer time and want to drill 3/4 – 1-inch holes, then go with models having a $250 or more price range that offers powerful motors.

12. Durability and Warranty

Check the warranty duration offered by a given rotary hammer drill before buying it. While most options out there come with a 1-year or a 2-year warranty, some more reliable and durable options come with a 5-year long warranty. Alike warranty duration, you have to check the build quality of a given rotary hammer drill. Choose a hammer drill that is built well to withstand wear easily even while using it against hard and rough surfaces.

Tips to Use the Rotary Hammer Drills:

Here are a few tips to follow for safe and effective usage of rotary hammer drills.

• You have to ensure this tool must obey OSHA standards, which regulate consumer products about their safety and quality control.
• Prefer to tackle small areas at a time and occasionally take short breaks while operating a rotary hammer. Thus, it not only cools down the machine (not heat up quickly) but also let you experience hand fatigue.
• It is important to protect the nose and eyes while using this drill. If not, dust and debris may enter into your nose or eyes. Also, this protective gear will prevent dust inhalation and thereby the risk of causing any injuries.

Benefits of Using Rotary Hammer Drills:

We are benefitted in several ways by using the rotary hammers. Here we have mentioned a few amazing benefits offered by using this hammer.

• Powerful: This rotary hammer is a powerful tool that offers more impact energy, which makes it an ideal option to do tasks, requiring drilling large holes into tough or hardened concrete. Alike lighter jackhammers, they are good at hammering and doing demolition or construction works.
• Different Settings: These hammers offer more than one setting, that lets you set the drill mode, the drill/hammer mode, and the hammer mode. For instance, if you set hammer-only mode, then the tool won’t rotate and works perfectly for carpentry or light demolition work. So, a rotary hammer with a different setting lets you do more tasks quickly and accurately.
• Comfortable: It provides a proper grip and vibrates less. It has a large rear handle and adjustable front handle to maximize its stability and let you work for a long time. Though its rate of blows is slow, yet offers more powerful impacts, which makes you apply less force for doing more work.
