Rotary Hammer Drill Buyer’s Guide
What is a Rotary Hammer Drill?
A rotary hammer drill is a heavy duty drill machine used for purposes of boring deeper and larger holes through concrete and other masonry materials. In place of spinning discs in standard hammer drills where the hammering strike results from the up and down movement of the two discs, the striking action in a rotary hammer drill comes from a piston system which compresses the air and uses air pressure to generate greater force.
Anybody who has worked with both hammer drills and rotary hammers will know the difference. Rotary hammers can bore larger and deeper holes through different sorts of masonry material (stone, brick, poured concrete, etc.). So, this is the ideal tool when you are taking up bigger projects since it will require you to do less work and will, on the whole, make the job easier and less strenuous for you.
At the same time, rotary drills can easily be switched to hammer-only mode and this is useful when you are doing light demolition jobs. However, unlike hammer drills, they can never be used in the manner you use a conventional drill, i.e. to use it for woodwork, plastic or metal. Even at the hammer-only mode, the power of the machine is too great to let it work on timber.
What to look for in a cordless rotary hammer drill?
Cordless rotary hammer drills are just what they say—a rotary drill without a cord. This tool comes handy at situations where it isn’t safe to operate a corded drill or at places where it is not easy to access the power source.
Now, with cordless drills (both standard hammer and rotary hammer), the common notion is that they don’t pack as much power as corded machines do. This may have been true if we were talking of older models. But, the latest cordless models include heavy duty hammer drills and SDS rotary hammers and these machines pack just as much punch and power as their corded counterparts.
If you are opting for a cordless model, make sure to check if it comes with detachable energy packs. The advantage here is that you have at least two energy packs and this means that while one is at work, you can put the other on recharge and the batteries will commonly get fully recharged within an hour. This means no loss in terms of work time and therefore, no loss in revenues.
Cordless hammer drill vs cordless rotary hammer drill
The motor: (brushless vs non-brushless)
Many cordless hammer drills use brushless motors in place of the conventional brushed or non-brushless motors. Many manufacturers also refer to the brushless motor technology as the ‘smart’ motor. Now, there is a tendency to wave off the claim that brushless motors last longer than brushed motors as a simple marketing gimmick.
However, we can assure you that this is not so. What happens in case of brushless motors is that in place of the brushes (little carbon filament blocks), here an electric circuit board is attached o the motor shaft and this board supplies the current to the copper coils of the armature.
Contrary to the above, in brushed motors, two brushes are attached directly to the commutator of the shaft and when you switch the machine on (no matter whether corded or cordless one), the commutator passes the electric current generated by the brushes to the armature of the motor. Now, since the brushes are in constant physical contact with the commutator, there is a friction involved and this contributes to the gradual wearing down of the motor.
So, yes—the brushless motors do come with a longer life. However, as you may imagine, this type of motor is also more expensive since they involve the superior and more complex technology of the electric circuit and the sensors.
RPM, Torque, BPM
Torque is an important factor that you must pay close attention to when looking to buy the best rotary hammer drill. The torque rating refers to the twisting power of the drill. The higher the torque of your drill, the higher the twisting action it can produce.
Now, what torque rating you should go for depends largely on the kind of job you will perform most frequently with the machine. For example, if you are required to drill deep holes on a regular basis, you will need a rotary drill with higher torque which commonly comes with larger spline drive hammer drills.
Similarly, BPM and RPM relate to the drilling speed of a particular model. RPM or rotation per minute is more important when it comes to simple hammer drills where the higher revolutions per minute itself translates to stronger hammering action. On the other hand, the BPM or the blow per minute is more important for rotary drills. As a rule of thumb, an RPM of 1200-1500 is ideal for medium to heavy duty jobs. However, if you need a more powerful machine, you should look for models with over 2000 RPM.
The clutch is again an important component for all hammer drills. Today’s hammer drill models come with clutch-protected motors. This means that if you are drilling a deeper hole with not enough torque, it will create extra pressure on the motor. In earlier models, the motor itself would have worn down fast, but now since the motors are clutch-protected, the clutch itself will wear down and this may mean more downtime for your machine. For heavy-duty jobs, we would recommend you use a model with 24-position clutch which allows for higher torque regulation. Also, look for models that come with a unibody powetrain which is helpful for maintaining proper alignment between motor, gearbox and the clutch.
The Chuck: (SDS Bits vs regular drill bits)
Both corded and cordless hammer drills come with standard adjustable chucks. This means that you can use different varieties of bits for different jobs when you are working with your hammer drill. Rotary hammer drills, on the other hand, are outfitted with spring-loaded chucks that correspond directly to specific-sized bits. This means that with a specific chuck, you can only use bits that fit with that particular chuck. SDS bits are most commonly used in rotary hammer drills. Normally, there are two varieties in the SDS bits—the SDS Plus and the SDS Max. The former are ideal for drilling holes in a range of 5/32 in. to ¾ in. diameters while the Max bits are designed for drilling even larger holes—in a range of 3/8 in. up to 2 in. Compared to the above, the regular bits used in hammer drills (for masonry work) can typically drill holes with diameters from ¼-in. to 3/8-in.
When it comes to cordless drills, a stronger battery means that you will get more power from the drill. However, keep this in mind that stronger batteries will also make the drill heavier and less convenient to use. Commonly, an 18v or 20v battery will be fine for medium to heavy-duty applications. You may need higher voltage batteries for industrial applications such as 36v.
Also, make sure to check whether or not your drill accessory pack comes with a two-pack battery. This is important when working with cordless hammer drills since you can put one battery in charge while the other is in use. This is especially relevant for cordless rotary hammer drills as they are normally used for heavy duty jobs which may often take longer to finish than the capacity of a single battery.
If you are buying batteries separately, always purchase two-battery packs. This will save you a good bit of money than if you had bought them singly.
What type of material you’re drilling
Again, whether you will use a hammer drill or a rotary hammer depends partly on the material you’ll be drilling in. Both types are meant for poured concrete, stone block and masonry materials. However, if you will not be drilling a number of deeper and larger holes lying in close proximity to each other, you may not need a rotary drill after all. So, consider the jobs you will be performing before investing your money. The regular hammer drills, apart from being cheaper, can also work on materials such as plastic, metal and wood or timber. Rotary hammer drills, on the other hand, are meant exclusively for work on concrete and masonry.
1.What’s the difference between NiCad & Lithium Batteries?
Nickel-cadmium or NiCd batteries are what you will find with most older and some current cordless drill models. However, they are getting quickly replaced with Li-ion or Lithium-ion batteries. To start with, Li-ion batteries are more environment friendly. These batteries also recharge quickly and they provide the user with a more stable power source. The reason why some current models still include NiCd batteries is that the latter perform better when the drill is used fairly regularly for heavy duty applications. The NiCds are also slightly better when it comes to delivering high range power over the lifespan of the battery. However, the NiCd batteries are much more toxic and the fast improvement in the Li-ion battery technology may soon make the NiCd batteries completely obsolete.
2. Which drill voltage should I choose? 18v, 20v, 36V
You must choose voltage according to your job. A 18v battery should suffice for most medium size regular hammer drill jobs. However, if you want to be on the safe side, you may go for 20v. For heavy works and for working with rotary drills, the norm is the 18v. How about 20v then, you may ask? Well, to put it simply, 20v is a marketing gimmick and you would scarcely notice any difference between an 18v and a 20v battery. Also, when a model flaunts 20v, understand that it is actually referring to the no-load max voltage and not the nominal voltage of 18v. As for 36v batteries, they are meant only for professional grade jobs and are used in industry settings only.
3. What does the “ah” mean in cordless batteries??
“Ah” in a battery pack is an abbreviation of the amp- or ampere-hour and it is a measure of the capacity of a battery pack. Generally, higher values mean additional power and longer runtime, though this may vary depending on some other factors (For instance, Li-ion battery technology has advanced to the degree that it is possible to build same size cells with better performance and greater charge density.). Power tools such as cordless rotary hammer drills are compatible with high capacity, compact battery packs.
4. What does variable trigger speed mean?
Variable trigger speed in power tools such as hammer drills means you can set the tool to a certain torque speed or a speed range depending on the nature of your job. In all current models, you can control the speed with the help of a trigger. Further you pull back the trigger, the faster will be the speed of the hammer drill. According to different cordless hammer drill reviews, the best models will also include a pre-set stop feature as well as two or more variable speed ranges.
