Rotary Hammer Drills Buying Guide
Rotary hammer drill or impact drill?
You can easily confuse a rotary hammer drill with an impact drill – they look almost the same.
Moreover, both machines have a pistol grip and can work with drill bits. Both the rotary hammer drill and the impact drill have a drilling function with a blow. The last similarity is that both machines can be wired or not.
However, the differences are also not to be overlooked.
Apart from the obvious that the rotary hammer drill can drill larger holes on many more surfaces (even concrete), there is a difference in how the impact force is applied to the drill bit.
This type of drill has improved drilling due to the two grooved discs located opposite each other.
These thick discs are asymmetrically arranged, which allows one of them to rise rapidly upwards with each rotation and then to return downwards while the other rises. It is these movements that add blow force to the drill chuck and make it easier to insert longer drill bits into harder materials than with a conventional tool.
Also, due to the impact function, smaller drill bits can be used for faster drilling in walls and concrete.
Impact drills are actually ordinary drills with an added blow function.
Rotary hammer drills
Rotary hammer drills have a more powerful impact, which is not performed by two grooved discs.
This is the reason why they are much better for the purpose than impact drills – inside them, there is a piston that compresses air and thus creates a strong blow.
Accordingly, in the case of rotary hammer drills, most of the blowing force comes from the piston and less from the rotation. The rotary hammer drills cannot turn the drill as fast as an ordinary drill tool, but they have a much more powerful blow. In fact, many models have an impact-only function, which allows them to operate without turning the chuck.
Simply put, the rotary hammer drill is like a small hammer, which also has the ability to drill.
Choosing a rotary hammer drill according to your needs
Good rotary hammer drills are those that perform excellently day after day in all kinds of tasks, such as drilling in concrete or walls.
But to choose the best rotary hammer drill for you, you need to consider what it will be used for.
Maybe you will just drill, or you will have to crush with it?
If you are unsure, it is best to focus on the most powerful model that falls within your budget. Larger and more powerful rotary hammer drills can withstand heavy daily use and thus save you money in the long run.
The rotary hammer drills with cable vary in price.
Smaller models are expected to be at the lower end of the price range, while more powerful ones can reach their upper limit. Of course, it is possible to find cheaper rotary hammer drills, but they will probably be from an unknown manufacturer and therefore of unproven quality.
Keep in mind, however, that the largest and most powerful rotary hammer drills are usually made and optimized for much heavier work.
Thus, an ordinary rotary hammer drill can have a drilling function only, which will allow you to use it without the blow. However, on larger models, you will hardly find something like this and the blow function will always work.
Rotary hammer drills are heavier and more expensive than ordinary drills. Think of them as an investment that will save you a lot of time when you have to drill a lot of holes, especially if they are in concrete or a wall.
What to look for in a rotary hammer drill?
The vibration control function is especially important when working with the rotary hammer drill all day. Vibrations are usually absorbed by a rubber pad and an additional softening layer.
The straight and reverse rotation mode of the chuck will allow you to remove the drill bit from the deep holes faster and easier.
You will also be able to unscrew and tighten screws, bolts, fasteners, and whatever else you can think of.
The demolition function allows you to work with the rotary hammer drill only on impact, without rotation. This way, by attaching various attachments to the chuck, you will be able to easily crush anything you want.
The control function automatically shuts off the machine’s motor in the event of a drill jam. This prevents the entire rotary hammer drill from turning and falling out of your hands. Such a feature may be useful to some or undesirable to others.
The ability to change the speed allows you to choose how fast the chuck rotates.
This is usually done with a pressure-sensitive trigger. Some models even have a locking mechanism that allows you not to hold the trigger constantly, but to drill at the set speed.
The slow start function rotates the chuck of the perforator slowly and gradually increases the speed. This is extremely useful from a safety point of view and also if you are going to drill into more fragile materials.
The built-in LEDs in some rotary hammer drills will allow you to see better where you are drilling, especially when working in low light.
Dust extractors allow you to collect dust and fine particles that fall when drilling. This is usually done in a bag built into the rotary hammer drill or by means of a vacuum cleaner attachment. Some manufacturers also offer additional accessories for their tools, which are usually purchased separately if needed.
Brushless motors in rotary hammer drills are more efficient and cooler, which allows them to last longer for continuous operation and also allows the installation of additional functions in the machine.
Blow button models will allow you to turn off the blowing function when you don’t need it, so you can use the drill as an ordinary one.
Corded or cordless rotary hammer drill?
Corded rotary hammer drills
Corded models are powered directly from the mains and will allow you to work continuously. They usually have a cable long enough not to interfere with normal operation.
Corded rotary hammer drills are also a little cheaper than cordless ones, especially if you need to buy additional accessories such as batteries, chargers, etc.
Cordless rotary hammer drills
These models are easier to use because you can pick them up anywhere and don’t have a cord to get in the way. A cordless rotary hammer drill would do an ideal job if you had to work on a ladder or scaffold.
Batteries that are in quality brands can withstand enough work with one charge. Usually from a 6 amp/hour battery, you can expect to drill about 200 holes in concrete with a single charge.
What to look for in a cordless drill:
- Fast-charging models can save you valuable time, which you would otherwise have to spend waiting for the battery to charge.
- Cordless rotary hammer drills come with different sizes of chucks, so keep this in mind when choosing.
- It is also good to check the accessories that come with the kit and whether you can buy more later.
- Brushless motors are also the more efficient option here because they will allow you to do more work with a single battery charge.
Rotary hammer drill accessories
Rotary hammer drills, especially those with a blow function, can use special addons to do anything above drilling holes in concrete.
For example, a tile addon will help you clean a tile wall very quickly and easily. In this way, the rotary hammer drill becomes an excellent choice for bathroom repairs.
A demolition addon can easily turn the rotary hammer drill into a small hammer with which to crush concrete and walls.
You can find all kinds of rotary hammer drill addons, even those that help you smooth out various surfaces and even break up heavily hardened soil.
How to compare different models of rotary hammer drills
Probably, after looking for the best rotary hammer drill, you already have some ideas of what it will be used for. In order to choose the right size and model, it is good to consider what holes you will drill with it.
The bigger they are, the more powerful model you will need.
Also, consider how often you will use the machine. If you plan to use it once or twice for repairs in your home – probably a smaller and cheaper model would do the trick.
However, if you make a living from construction work and will be used often – then do not hesitate to choose a high-end model.
This is the actual power of the motor, which is measured in watts. Very often, however, manufacturers give the input power, which is greater than the output. This is because factors such as drilled material, tools used, etc. affect the power of the motor directly during operation.
The power of the corded models is given in amperes, while the battery models are given in volts. For cordless rotary hammer drills, the average operating time can also be calculated from the battery indicator, which is usually given in amperes/hours.
Impact and speed
Like most blowing power tools, rotary hammer drills have a specification for blow strength. It is usually given by manufacturers in the form of joules and the more they are – the more powerful the blow.
The nominal speed of rotation is given in revolutions per minute and compared to ordinary drills, the rotary hammer drills are slower and rotate at speeds below 1000 revolutions per minute. A lower speed is actually a better indicator when it comes to a perforator.
The fact that a model is slower means that its impact is stronger, which is usually more important. The impact speed is given in the form of blows per minute and usually, the rotary hammer drills can reach 4000 or more.
Again, it is important to check this indicator, as you probably want the drill to do a good job for you when drilling. Usually, the maximum drilling diameter is given in millimeters.
Manufacturers often give different diameters depending on the surface to be drilled, such as wall, wood, metal, concrete, etc.
