Electronic equipment had seen a lot of revolution throughout these years. In a General sense, we can put a clear border between two major types of tools- power tool and hand tool. A hammer drill is one of the vastly used power tools by electricians, carpenters, plumber and literally any handymen.
In today’s post, we will provide you with a hands-on guide on what is a hammer drill, types of the hammer drill, use of them along with a few users’ tips.
What Is A Hammer Drill?
Hammer drill is also known as percussion drills or impact drills. It is a power tool which is majorly used for drilling in hard material. A hammer drill is nothing but a variation of a rotary drill provided with an impact mechanism to generate hammering motion in it.
Due to the Rapid repetition of short hammering forces, it can hold the materials and provide quicker drilling. Comparing to other boring and drilling tools, hammer drills take a lot less effort.
Turning off the impact mechanism in a hammer drill, you can use it as a conventional drill or screwdriver as well.
Have a look at how a hammer drill works-
How does a hammering drill work?
Right after the definition, let’s talk about the operation and how does it work in practice.
The mechanism that is used in hammering drill is called percussion hammering mechanism. Two sets of toothed gears are interacted with one another and that combined rotates the drill bit. There is a chuck and the chuck and bit move forward and backward to provide enough motion which creates rotation.
The clutch that you can find inside a hammer drill rotates around the drill bit and pushes it in and out. In this manner, a number of blows or impact is created which provide forces on a frequent basis. The frequency is there around 1000 blows in one minute.
This repeated blow is what you can get to break concrete and to create drills inside hard materials. For the same reason, a hammer drill is able to provide more impact forces compared to a regular drill.
Types of Hammer Drills:
Based on using, material and mechanism, hammer drills are of many types. Here is a quick list-
Dedicated hammer drill
Dedicated hammer drills are also called Rotary Hammers. When you have to do a lot of masonry drilling jobs, this is the go-to tool that you will need. The expense of this type of drill is quite off the mark. As a hobbyist mechanic, the price can be heavy on you.
Corded hammer drill
When you have to do an electrical job and you have power outlets available nearby, you would like to go for a corded hammer drill. In terms of rotational power (RPM), they are way higher than any other types of hammering drills.
Some of the brands are likely to produce portable versions of such corded hammer drills. For obvious reasons, they are powered by DC batteries.
Cordless hammering drill
The kind of hammering drill that we have talked in the previous section comes as a smarter version as cordless hammering drills. They are very handy when you have to do highly rotational hammering works and don’t have any AC power outlet nearby.
The battery power of cordless hammering drills is near around 18V. With a fully charged battery, you can easily drill 100 to 120 holes.
In terms of price, they are higher than corded hammering drills.
- To create holes and drills in hard materials, hammer drills are used with concrete screws, anchor bolts, and wall plug. For both household and commercial purposes, search users are frequently done.
- To create different sizes of holes in stone, concrete, ceramic and masonry, hammer drill sir frequently used.
- To create a concrete footing in order to pin concrete wall forms, hammer drills are used.
- You can turn a hammer drill into a regular drill for woodworking or metal working just by switching off the hammer clutch.
- When you have to place a bolt for the window or the door of your room, the first thing that you need is a hammering drill. With the conventional normal drills, it takes a whole lot of pressure and often leads to imperfection.
- To keep the drills uniform, smooth and straight, there is hardly any alternative of hammer drills.
- In some of the modern hammer drills, you get to operate them on battery power. So, no matter wherever the work piece is, you are ok to go.
Hammer drill has a long history of being the most favorite tools when it comes to percussive drilling. Brands are competing with each other you come up with optimal value in terms of performance and features.
Therefore, you have tons of options and models in the market to choose from. And the guide that you have just finished reading; he is expected to be your first guide to that.
