What is Hammer Drill?
A hammer drill is a rotary drill with a specific hammering action. It is extremely useful for drilling holes in masonry materials like concrete and stone.
Hammer Drills are some of the most common power tools found in both households and construction work sites. They are also known as rotary hammers and impact drills and they are often used to drill holes or chisel in hard mediums like stone, concrete, and masonry. Most of these perform all of the same activities, but they vary widely in terms of power and certain features that are better for dealing with certain types of materials. More power is not necessarily better depending on how the hammer drill will be used. Here are some general tips to consider before you decide to purchase a hammer drill.
1. How you will use the hammer drill
First of all, you need to really think about how you plan on using the hammer drill because that will determine what type you should buy as well as what features you will need to have. Generally, most people are able to suffice with a moderately priced, cordless hammer drill.
2. Try to stay with the major brands
Brand name does not always equate to high quality, but they tend to be some of the better made products compared to the generic ones on the shelf. Everyone tends to favour one brand or another based on their own personal experiences and preferences, but brands like DeWalt, Ryobi, Bosch, and Hilti are all pretty reliable brands that should provide a lot of bang for your buck.
3. Look for a strong grip
Since hammer drills are very powerful and they tend to vibrate very hard, it is important that you are able to find one that you can use comfortably. Some hammer drills have an anti-slip grip handle that will help you keep a grip on it during your work. Some handles may feel too, heavy, wide or slippery to grip properly when the hammer drill is on, so check to make sure that it feels comfortable.
4. Do not simply buy the cheapest model on the shelf
Never try to buy the cheapest model on the shelf because you usually get what you pay for. Try to look for a model that has the whole package, meaning that it is comfortable, moderately priced, and has all of the features that you will need.
5. More is not always better
A lot of people will compare the amount of power that a hammer drill has a means of selecting the best one, but in this case more is not always better. Usually, the hammer drills that tend to have more voltage and torque are much heavier than the other ones and they tend to have cords as well. It is not necessary to have that much power unless you are doing some heavy duty work with really hard materials like concrete. Most hammer drills have voltage that falls in the range of about 12V at the low end all the way up to about 28V at the high end. The mid range is usually about 18V for hammer drills and that should be enough for most jobs.
6. Cord vs Cordless
Hammer drills with and without cords all have their own advantages and disadvantages depending on your needs. A cordless hammer drill is the preference of most average users that may only use it around the house or for personal projects. They are relatively inexpensive, they get the job done, and they comfortable and lightweight. The downside of a cordless hammer drill is that they tend to have less power and they do not have long battery life. The hammer drills that have cords attached tend to be even more powerful, they have stronger motors, and they also tend to be better for heavy duty jobs. The problem with the cord is that they can restrict your movement, they are heavier, and they tend to be more expensive. Basically, cordless hammer drills are good for casual use around the house, but the hammer drills with cords are better for use in demanding professional environments to break up concrete and masonry.
7. Look for a warranty
Try to check and see if the hammer drill comes with a warranty. A lot of power tools usually come along with a 1 year warranty from the manufacturer that protects against poor workmanship and defects, but not accidents and misuse. The warranty should protect you just in case it does not work properly, so find a hammer drill that comes with one and be sure to register it as soon as you buy it.
Hammer drills have become quite common and many people need them to penetrate hard materials. All hammer drills are not created equal as it depends on how you plan on using it, so keep all of these tips in mind, consider your needs, and then select the best model for you.
