Standard hammer drills are powerful tools that can drill through a variety of tough materials, but even the best can’t make a hole beyond about ½ inch in diameter.

That’s when the rotary hammer drill takes over. These mighty tools have little trouble drilling through concrete slabs, concrete blocks, stone, and other tough materials. Drill bits that are a foot long or more are common. Flip a lever, and the same tool becomes a compact demolition hammer. It can strip tiles from walls, knock down brick walls, and break up asphalt.

A rotary hammer drill sounds like a fearsome tool, and some do have impressive capabilities. However, there also are very manageable models aimed at the DIY enthusiast. Keep reading to learn how to choose a rotary hammer drill for a variety of purposes, and check out the list of some of the best options on the market below.

How We Chose the Best Rotary Hammer Drill

A great deal of research went into making our selections, which is conducted by experts with years of experience and in-depth technical knowledge. I am an engineer by trade and understand the key features in determining performance. I also have undertaken two complete house renovations using this type of tool, so I know first-hand how a rotary hammer drill functions.

I believe the most important factors to look for in rotary drills are available power, recommended maximum diameter, and impact energy. These largely determine the force that can be applied to a particular task and differentiate DIY tools from pro models.

I also have given consideration to the manufacturers’ reputations. Certain brands have long-standing reputations for reliability and durability. That said, I was careful not to overlook a bargain even if the maker is not one of the big names.

What to Consider When Choosing a Rotary Hammer Drill

The popularity of rotary hammer drills gives the potential buyer excellent variety, but options can lead to confusion. The key performance and physical aspects will dictate the best rotary hammer drill for your specific needs, and ensure you obtain maximum value from your purchase.


Before considering the various technical aspects of rotary hammer drills, it’s important to know whether a corded or cordless model is best for your needs. Cordless models dominate the market for standard hammer drills, but it’s not quite so clear cut when it comes to rotary hammer drills.

Battery power is clearly the convenient option, but rotary hammer drills are power-hungry tools. The 18- or 20-volt battery used for standard drill/drivers, and rated for 1.5- or 2.0-amp hours, would offer very restricted runtimes. There usually are 3- or 4-Ah versions provided, but a spare battery is something of a necessity for those who want reliable continuous operation. An extra battery adds a substantial amount to the price, so a cordless rotary hammer drill often ends up being significantly more expensive than a corded model.

It’s worth mentioning that “bare tools” often seem like a great value, but they come without a battery or charger. If you already have other cordless tools from that manufacturer and the equipment is compatible, then you can save money by buying a bare tool. However, always check the specifications carefully before purchasing.

While cords can be inconvenient, and most of the time an extension cable would be required, they do provide consistent power for all-day working. As a result, around half of the best rotary hammer drills available are corded.


Corded tools are rated by the amps that the motor uses. Rotary hammer drills tend to be as low as 8 amps and increase from there. The most powerful models are 13 or 14 amps. While 15 amps is a theoretical maximum (the most a standard outlet can supply), most manufacturers allow a margin that reduces the chances of a breaker tripping if there’s a power surge.

Cordless tools are rated by voltage, and range from 18 to 36 volts. While the rating shows the maximum power available, it’s also important to consider the amp hours of the battery (or batteries). Amp hours can be compared to the amount of gas in the tank. For example, a 4.0-Ah battery will run twice as long as a 2.0-Ah battery. While this may not have a major impact on DIY users, professionals who want to maximize runtimes want the highest Ah batteries available.


Most hammer drills give a figure for rpm, but rotational speed isn’t very important for rotary hammer drills. Some manufacturers provide it, but many do not. Instead, the majority rate the tool’s capabilities by giving a maximum hole diameter. Sometimes two are given, one for a solid drill bit, the other for a core bit (often used to bore holes for pipework).

The other important performance figure is the impact energy, effectively the power of the hammer action. This is often given as foot-pounds but sometimes as joules (J), which is the international system for measuring energy: 1 foot-pound = 1.356 joules.

BPM or impacts per minute (IPM) are frequently quoted. It’s the speed of the hammer action. A faster speed can be assumed to mean more aggressive performance, but actual impact energy is a more accurate measure.


Most rotary hammer drills use an SDS chuck. These do not open and close like a standard three-jaw chuck. They have a sliding sleeve and a mechanism that clamps onto slots in the drill bit or chisel. It’s a very positive locking method with no chance of the bit slipping.

There are two sizes. SDS and SDS-Plus have a 10-millimeter shank. SDS Max has an 18-millimeter shank. While SDS bits will fit SDS-Plus tools, they will not fit SDS Max or vice versa, so it’s important to buy the right size bits.

There is an alternative on some hammer drills called a spline chuck. The bits have splines that lock them in place rather than slots. Spline chucks are much less common, and bits are not interchangeable with SDS.

Operation Modes 

One of the reasons rotary hammer drills have become so popular is their versatility, with three distinct operating modes available.

The first two are much like what’s found on any hammer drill. It can be used as an ordinary drill, which simply rotates. Operating a lever or switch adds a percussive hammer action. This is much stronger on a rotary hammer drill than on a standard hammer drill.

The third mode disengages the rotary action and the tool works entirely as a powerful hammer, to which chisels of different widths can be fitted. Broad ones can make short work of removing tiles from walls or floors. Narrower and pointed chisels can be used for demolition work, including breaking up concrete slabs or asphalt.

Design and Ergonomics

A rotary hammer drill can be quite a bulky tool, but they are usually well balanced. Handles are open to allow for use with gloved hands. A large trigger also helps make the tool easier to use. Rubberized areas increase comfort and provide a secure grip.

An auxiliary handle that can rotate 360 degrees is usually provided at the front, allowing it to be moved to where it offers the best additional support. A rotary hammer can generate a lot of torque, so the additional handle helps keep it under control. Not using it can risk a nasty wrist injury.

Given that these tools have a powerful hammer action, it should be no surprise that they vibrate. This can quickly prove tiring for the operator. Better models have vibration control, generally some kind of shock absorber between the main body and the handle.

Attachments and Accessories 

The main accessories for rotary hammer drills are the variety of SDS drills and chisels already mentioned above. These usually need to be purchased separately, though some tools include them. Many models have a handy depth gauge for use when drilling.

Rotary hammer drills often kick up a lot of dust, some of which has been linked to lung and kidney diseases. Even though some of the better rotary hammer drills incorporate dust ports that can be used in conjunction with other extraction equipment, always wear respiratory protection while using a rotary hammer drill. While this is a matter of personal choice for the DIY user, OSHA now has rules concerning workplace exposure, so it could well be a necessity for the professional.


The article above contains a lot of valuable information that explains the technical aspects of these tools and can help you choose the best rotary hammer drill for your needs. However, during our research we found a number of common questions that are of concern to potential buyers. The following section addresses those questions.

Q. What’s the difference between a rotary hammer and a demolition hammer?

Generally speaking, a demolition hammer is even more powerful than a rotary hammer. It is focused on demolition and does not have a drill function.

Q. What’s the difference between a rotary hammer drill and an SDS drill?

Largely they are the same thing. SDS describes the type of chuck. These are SDS, SDS-Plus, or SDS Max. The majority of rotary hammer drills are fitted with one of these, and a few use what’s called a spline chuck instead.

Q. How long does a rotary hammer drill last on average?

It is impossible to say how long a rotary hammer drill will last, because it is dependent on the amount of use it gets and how hard it works. For light DIY use, a rotary hammer can last many years. Used every day in a tough job site environment, then it may last perhaps 2 or 3 years.

Q. How do I maintain my rotary hammer drill?

Rotary hammer drills are rugged tools that don’t need much maintenance. Some need periodic lubrication of the hammer mechanism, though others are sealed. Those with brush motors will eventually need to have the brushes replaced. On average this is required every 7,500 hours. Check the manufacturer’s instructions for a specific tool’s maintenance requirements.

Q. What does SDS mean?

Some say SDS means Slotted Drive Shaft. However Bosch, who invented it, calls it the Slotted Drive System.

Q. What does 1-inch SDS mean?

The SDS dimension is the maximum recommended drilling diameter in concrete, though the actual maximum will depend on material. So 1-inch SDS means that the rotary hammer drill in question is capable of drilling a maximum 1-inch diameter hole. The biggest generally available is 1 9/16-inch diameter.

Q. Can I use an SDS drill bit in a regular drill?

No. A regular drill probably doesn’t have the power to use an SDS drill bit efficiently, but the main reason is that the regular chuck won’t hold them securely. Using them would be unsafe.
