Key Features of a Hammer Drill
You have some great options when it comes to your hammer drill. All of these are at the top of their game, but you don’t just want to choose your drill based on what your friends have, or what the brand is.
You need to be sure that your hammer drill will work for your specific needs, with the power, speed, size, and comfort that you’re looking for.
The power of your hammer drill will impact how quickly you’re able to get your work done. If you get a standard hammer drill, you’ll usually have a 7-amp motor. Larger options have motors around 10-amps. Needless to say, the larger the motor, the more power you have.
Don’t just pick your power tools based on the power levels though. A heavier and larger motor means that you have a larger hammer drill. It will be bigger in your hands, and may actually be more uncomfortable to use.
Power is important, but so is the actual power source. When you’re using your drill at home for light tasks, cordless hammer drills work fine. They’re versatile and able to be moved around without you needing to adjust the cord with every angle. This makes it simple to get into hard-to-reach places.
There are positives to having a cord though. Corded options have more rotations per minute and generally more power. Jobs go by faster this way, and you can work with tougher materials like stone or concrete.
Torque and Speed
The power and speed of the drill are determined by the torque, which is simply the force behind the drill when it rotates the drill bit into position. With more torque, you get more power and force.
The drill speed is about the number of revolutions or rotations that the drill performs per minute. Basically, the more rotations, the faster the drill.
The faster the drill, the more power you have, so you can work with materials like metal of concrete. You'll generally have faster speeds for corded options since they have more power and stronger motors.
There are also drills have a variable speed option, which is valuable because they offer you greater control. You can be more precise in your work and get better results, in the end, not to mention that you can drill many more types of material with the same drill.
There’s nothing more important than safety. When you’re using a hammer drill, you want to be sure that your drill is safe to use, which is why you might like it if your drill has a side handle. This handle will provide you with more stability when you’re using it. If your handles are ergonomic too, with shock absorption technology, that will make it even more comfortable for you to use.
Depth and Chuck
Check on the depth gauge when you make your purchase if you’re planning on making a lot of holes of a specific depth. Having a gauge to guide you will make your work more consistent. The chuck will help you add to that consistency when you change bits to fit. A keyed chuck lets you tighten your bits so they stay in place properly, and don’t move at all during operation.
Ease of Use
Using your rotary hammer drill should be easy, meaning that you may want to look for a forward/reverse switch. This lets you control the direction of the drill just by flicking the switch. If your drill gets stuck then, just flick the switch and reverse the motion.
What To Choose: Corded or Cordless Hammer Drill
When it comes to choosing power tools, cordless seems to be the obvious choice. However, more consideration should go into the decision. Yes, cordless drills lack annoying wires and cables that get tangled and/or limit the user's range of movement, but, thanks to their internal power source, they can also lack adequate power. This is because their power comes from within, making maintaining a constant supply of power kind of tricky.
To make the final decision between corded and cordless, the most important things to consider are the type of job that you will be doing, how frequently you will be using the tool, and whether you have the patience to drag around bulky cords to benefit from all that the traditional corded devices have to offer.
Tips for Safety
In general, the terms "hammer" and "drill" don't usually invoke feelings of peace and safety. Combined, they can certainly strike fear into the hearts of newbie DIYers and handymen.
Thankfully, there are ways to work with hammer drills that can reduce both the risks and fears that come with using them. In the following portion of this article, we go over a few of the best safety tips.
Wear appropriate protective equipment
When working with the cousin of the rotary hammer, it's important to wear appropriate clothing. This means that to operate the hammer drill you should equip yourself with earplugs, a pair of work gloves, and of course, durable safety glasses.
Avoid loose clothing
Anytime you’re working with a motorized tool, you should be certain to avoid wearing any kind of loose clothing. Yes, your favorite flowy shirt might allow for a nice breeze to pass through, but it can also prove to be a safety hazard.
Loose clothing can become tangled in the cordless hammer, which, as a result, can leave you with unexpected injuries that could have easily been avoided had you worn more tight fitting clothing.
Hammer drills are very useful tools. They are hardy, handy, and generally quite easy to use. There are a plethora of awesome models and brands to choose from, factors to consider before making a purchase, and safety tips that can make owning a hammer drill a much more pleasant experience.
With any luck, this article has given you a new insight into the world of hammer drills and given you the information you need to feel confident purchasing, using, and mastering the trade.
