Big projects call for big power tools, and the best rotary hammer drills will help you get the job done. They’re great for breaking up soil and concrete, removing tile, and drilling holes into concrete.If you’re renovating the house or working with concrete, this kind of tool can help. But first, what are the best rotary hammer drills, and what makes them so special?
What Is a Rotary Hammer Drill?
A rotary hammer drill, also known as a rotary hammer, has two functions. It usually has one speed for chiseling, and a piston within the tool is the source of its intense force. This setting is excellent for breaking up concrete.
Rotary hammer drills also do a fantastic job drilling into and through concrete (as opposed to breaking it apart). Its second function is to use rotations to drill holes. With the right bit, you can drill right through tough surfaces without much effort.
The best rotary hammer drills also have an SDS chuck, which has a design that prevents the bit from loosening over time. This makes it the perfect tool for intense drilling and hammering.
The difference between a hammer drill and a rotary hammer drill
When looking for the best rotary hammer drills, you’ll likely come across hammer drills as well. The names are almost identical, so it’s easy to mistake one for the other. However, there are key differences between these kinds of tools.
For one, hammer drills don’t have an internal piston. It's more versatile and lightweight with its variable speeds. This means that hammer drills can offer more blows per minute, but each strike doesn’t carry the same force as rotary hammer drills.
Hammer drills also typically have a standard chuck instead of an SDS chuck. Though this comes with the risk of the bit loosening over time, this kind of chuck is capable of ordinary DIY projects.
All in all, rotary hammer drills are better for more intense jobs, whereas hammer drills will do for the casual handyman.
Kinds of drill bits
If you buy rotary hammer drill bits separately from the tool, you’ll need to make sure they are compatible with the chuck. Generally, they’ll need to be SDS compatible. While there are several kinds of drill bits, there are five popular ones that work for most jobs.
For busting up concrete, use the cold chisel. The bull point chisel will start holes in concrete, and a scaling chisel will remove concrete and weld spatter, as well as rust. The tile remover, as the name implies, is perfect for removing tile.
The clay spade does a great job breaking up hard soil, but you’ll need an SDS-Max chuck to use it.
How to Use the Best Rotary Hammer Drills Effectively
Now, just because you have a large power tool, it doesn’t mean you can use it however you wish. Not only does this render the device ineffective, but it’s also dangerous. If you want to keep yourself out of the hospital and get the job done as soon as possible, be sure you use the best rotary hammer drills properly.
With a few simple tips, you can make every brand of rotary hammer drills effective and safe. This includes following the manufacturer’s recommendations, cleaning up along the way, and reserving your strength. By doing this, you’ll have more time to check off the rest of your to-do list.
Follow manufacturer recommendations
Most companies categorize their hammer drills by the largest hole it can drill. This doesn’t mean that they can’t drill bigger holes occasionally, but you shouldn’t do it consistently. This will wear out your drill faster than necessary because it’s continually working at its full capacity.
To find the best rotary hammer drills for you, you’ll first need to figure out what size hole you’ll be drilling most often. Once you know that, buy the rotary hammer that can start larger holes. This makes it so you don’t use the drill at its full capacity every time you use it.
If you need to drill a bigger hole every once in a while, start with a smaller one first. This puts less strain on the tool.
Clean up every so often
Technically, rotary hammer drill bits have a design that removes dust from the hole as you drill. However, it’s even better if you occasionally pull the bit away from the hole.
This will remove excess dust, which removes any unnecessary friction that will wear down the bit faster. Drilling through the debris will also put more strain on your tool. The best rotary hammer drills aren’t cheap, so you should do everything in your power to make them last.
Save your strength
Lastly, you should never push too hard while you use the best rotary hammer drills. This can break drill bits and even wear down the motor and gears. It also slows down the drilling process, so there’s no need to push as hard as you can.
However, there is a happy medium. With a bit of pressure, you can find the point where your rotary hammer will drill faster and more effectively. As you start drilling, add a bit of pressure until you find that sweet spot.
