A Little Background
A tougher tool than a regular hammer drill is a rotary hammer, which is designed for precision and bigger concrete drilling and power. In fact, most people who regularly use hammer drills may sometimes switch to a rotary hammer for better performance and for larger projects.
However, because a rotary hammer only accepts expensive SDS or Slotted Drive Shank type bits, these are not the tools to have if you don’t have a lot of budget. But if you are really serious with your job and you absolutely need better power and accuracy in the long run then you can buy a rotary hammer for yourself or for your industrial day job.
How We Picked
When we chose the best rotary hammer out there, we considered the following in our decision:
The drilling capacity of the rotary hammer is important. You will most likely find a rotary hammer that is capable of drilling from 1 inch and above through concrete and masonry due to its unprecedented power. You should also know the drilling capacity on wood and metal, but that’s just a secondary thing. What you will want to know is the drilling capacity for concrete and masonry, that’s why it’s called a rotary hammer.
There should be at least 3 selectable modes on the rotary hammer. In most cases, a rotary hammer should have 3 options: rotation only, drilling only or both. This sets it apart from regular hammer drills because it can rotate, hence the name rotary hammer.
Tough and durable gear housing should enclose the rotary hammer for better tool longevity. You would not expect a rotary hammer to last long if the casing was not too sturdy or if it was too flimsy. A rotary hammer should be durable but should not sacrifice weight so it will maintain your strength while operating the tool.
The weight of the rotary hammer should be considered as well as the handle design. Even if it is durable, it should also be easy to carry. Ergonomically designed rotary hammers are a big plus for any workers because it reduces their user fatigue and allows them to work for more hours without getting tired and risking hand injuries. Working on any power tool is a stressful activity and this is why they will absolutely need a tool that will not give you too much vibration on your hands while working, so you can focus more on what you are drilling on and not on the numbness of your hands.
A keyless chuck rotary hammer is a big plus for easy bit changing. This is a feature that you will find on most rotary hammers out there and any type of drill for that matter. It is important even if you do spend a bit of extra for easy tool changing. This works well for those who operate rotary hammers for a variety of purposes and have a wide range of bits to choose from for various material operations.
The variable speed ranges of the rotary hammer should also be good for its price. Do know the BPM (blows per minute) as well as the RPM (rotations per minute) which pertain to the impact and speed of the tool respectively. They should be easily set using a dial system on the rotary hammer.
The motor’s power should be reliable to service the rotary hammer itself. Know the amperage of the rotary hammer so that you will know how much power it will give your rotary hammer on any operation whatsoever.
The impact energy of the rotary hammer should be known. It is usually measured in Joules or ft/lbs depending on the unit used and this refers to how much energy or power the rotary hammer can deliver onto your work piece.

Other Frequently Asked Questions
Q: What is the difference between a rotary hammer and a hammer drill?
A: According to Electrical Contractor Mag , in general, rotary hammers require more expensive bits such as the slotted drive shank or SDS bits and chucks, which ideally makes them more expensive than regular hammer drills.
In addition to that, most hammer drills are for regular concrete breaking but rotary hammers are designed for heavy duty work. In point of fact, bit slippage is almost none when it comes to operating a rotary hammer due to the unique design of the SDS chuck and bit system.
Q: What you should you consider when using a rotary hammer?
A: According to For Construction Pros , it is recommended that you do not force the tool too much and let it do its job. You should always be alert on its warning lights if it shows some signs of problems. What’s more, the bit shank should be greased every time you change the bits so it does not result to the decrease in the productivity. You should always clean up debris and dirt after drilling and you must consider the material and hammer size first before deciding on a bit size. In fact, the greasing should be done only with recommended grease by the manufacturer. Remember these safety tips and you will have a great operation with your rotary hammer.
