When you hear the word jackhammer, we are just referring to a pneumatic or electro-mechanical tool that combines both a hammer and the chisels directly. Some of them are powered by gas while electric motors power others. Some of the people call it definite breaker or demolition hammer. Just like choosing other concrete tools, a jackhammer is one of the things that you cannot make the right choice quickly especially if you don't know what you should be checking. This is because there are some procedures to follow and things that you should know to make the right purchase. If not you might realize that it cannot serve you as expected and this might cost your integrity. Below is a list of some of the things that you will need to look into before you make your purchase.
You should know whether you will require electric, gas or pneumatic jackhammer. This will majorly depend with your intended use, the need for mobility and the need for power in your project. When you have a plan that will require continuous movement and high power supply it will be good if you buy the models that use gas. Besides, we have small plans that does not need mobility which is good with electric or pneumatic jackhammers. Generally gas models are always providing more power and versatility. We also have cordless ratchet models which are often cheap and lighter, but they require a constant connection to a source of electricity. We also have pneumatic models that use compressed air, are versatile, and they can best be used in breaking rocks and concrete walls. In this case, you should see the quality of the project before choosing one.
Besides, you should also consider percussion rate and impact. Percussion rate is the ability of the hammer to break the surface which is rates per minute. One thing that you should know is that the higher the percussion rate, the larger the motor and the higher the demolition power. Therefore, you should make sure that the electric jack hammer vs air that you choose has the capability that you want. It is always recommended that you choose the breaker that exceeds your requirements as this will help in prolonging the life of the equipment.
Besides, it is also essential to check the weight of jackhammer. With the weight of the breaker, you will be in a position to have a rough idea of the kind of duty it can handle. For the people who have significant projects that involve the demolition of harder covers, they should go for heavy concrete breakers. On the other hand, we have lighter jackhammers which are always handheld for the demolition of small projects such as ceilings, walls and other surfaces above the ground.
