Hammer drills as the name suggests is the device which helps you to dislocate concrete or other materials with its strong hammering power. If you want to drill a hole so that you can fix something on the wall, then immediately you turn to this particular gadget which will permit you to hang your favorite painting. This tool has definitely proved to be a very essential in our lives. Initially it used to be mostly used by the carpenters but now the manufacturers have started producing such user friendly ones that hammer drills have made a place for themselves in every household.
There are a plethora of hammer drills available in the market. Sometimes it becomes difficult to decide which will suit your needs. These devices are very similar to the drill drivers except for the fact that they have a pulsating hammer effect which will facilitate to drill holes into hard masonry surfaces which are otherwise very difficult. You get the cordless as well as the corded hammer drills in the market. The cordless ones are very handy, compact and portable. They can be taken along with you on your outdoor works too because they are not cumbersome and will easily fit into your tool box. But in case you have to bore big holes into concrete then you will need a much more powerful 120 volts hammer drills and these are the corded ones. These corded ones are heavy duty and they serve dual purpose because at the flip of a small lever they change from hammer mode to a non hammer mode. So you are able to drill a hole into the concrete as well as a hole into the wood using the very same tool but with a small alteration.
Types of hammer drills
There are two types of hammer drills available in the market – percussion hammer drill and rotary hammer drill. In the percussion hammer drills the rotation of the chuck causes the hammer action, the chuck along with the bit moves backwards and forward on the axis of rotation. Whereas in the rotary drills both the chuck and the bit move independently of each other and is powered by compressed air (pneumatically). This particular type can be only used in the hammer mode and is very effective when it is used on hard surfaces. These tools have a specially designed clutch which permits the drill to spin and at the same time facilitates it to move along the axis of the bit so that it can punch in and out. The force of the blow and the distance traveled by the bit are comparatively very small but the hammering action is very fast. A large number of blows per minute will ensure that holes are drilled into the stubborn concrete or brick.
These hammer drills are invaluable tools which help you to bore through very hard surfaces which will otherwise be very difficult to achieve with the help of the regular electric drills. Since this is a powerful tool so it is always better to read the owner’s manual before using it.
Using A Hammer Drill
A harmer drill is a device that has been designed specifically for drilling. However, this drilling device does the drilling accompanied by a hammering action. This is the reason why it is called a harmer drill. Sometimes a harmer drill can also be referred to as a rotary harmer and even a roto-drill. In other cases it has also been referred to as a hammering drill. Therefore, when you come across all the terms that have been indicated above, just know that they are referring to the harmer drill. This tool has found a lot of uses in industry and even domestically.
When using the harmer drill it is advisable to always make sure that you have taken all the necessary precautions. Most of these precautions are based on the safety of the individual who is using the drill. Some the precautions include ensuring that the user is wearing safety boots. A drill may be used for objects that cause harm to the user’s feet. Therefore, wearing safety boots is not an option. Sometimes the user can also wear safety gloves; unless one is very sure that the fingers are safe during the usage of the drill. All these precautions have to be adhered to as strictly as possible to prevent accidents when using the drill.
Basically both a harmer drill and a drill work in the same way. However, the hammering action that is provided by the harmer drill is advantageous. This is because it provides a rather short but rapid force that is essential for the pulverization of very brittle materials. Therefore, do not use any other harmer when you are dealing with brittle materials. The harmer drill has been proven to be very effective in as far as the pulverization of brittle materials is concerned. Its short but rapid hammering action also enables it to provide a quicker drilling action with the application of less effort.
How is the harmer drill powered? In most cases, these drills operate with electrical energy. This can be sourced in any available methods; especially AC power and sometimes DC power when the battery is involved. Obviously plans are underway to come up with harmer drills that rely on other sources of electrical energy such as solar, geothermal and wind energy.
In terms of energy transformation, a harmer drill transforms electrical energy into mechanical energy. The mechanical energy is then used to drill the object until the required amount of drill has been achieved. Although the basic action of a harmer drill has been identified to be drilling, different types of harmer drills have been recognized. The main types of harmer drills are the Cam action drills and the Electro-Pneumatic drills. All the drills that rely on lower power units for their operation are called harmer drills for simplicity and their drilling action is usually cam in nature. Higher power unit drills are usually referred to as rotary drills. These drills have found a wider application in industry, especially in mass production technology.
