When you know the difference between impact driver and hammer drill, it will help you to choose one of them that seems good for you. The impact driver is a cordless driver which is known as a popular portable tool to carpenters, handymen, electricians, and also for us. The functions and handling process of impact driver and hammer drill are different.
Hammer drill is used to drill hard surface but impact driver is used to installing or removing screws and nuts. So, it is better to know the features of two and distinguish them. Then take a decision what type of drills are suited for your work and what benefits you get from them. However, you can drill any hard materials with these two drills. In this article, we are going to explain you the difference between an impact driver and hammer drill and what is best to buy.
What is impact driver?
The impact driver is a small but strong tool which can rotate suddenly. However, mechanics use it to lose the screws and nuts. The outer sleeve of the impact driver is heavy and it surrounds an inner part. The user can strike the outer sleeve of this tool with a hammer because hammer forces it down into screws. It is a very essential and useful tool to do various tasks such as any Dry projects of home, repairing the car, etc. The impact driver is as like as traditional drills it has much rotational torque. If you manually want to unscrew a bolt, it will take a lot of time. But when you use an impact driver, it delivers 50 bumps a second and you get the screw easily.
What is hammer drill?
It is also known as a rotary hammer because it is the drill with a hammer. Hammer drill works rapidly to pound brittle material and provides you the quicker drilling without much effort. It can be an electrical one or works with battery power. The technology of it is similar to the demolition hammer or breakers. However, it is designed for drilling concrete, brick, mortar, and stone. When you operate a hammer drill, it will rotate as a normal drill. It is better to learn how to handle a hammer drill.
Mechanism of hammer drill and impact driver
Hammer drill makes direct force as like as a hammer. The hammering mechanism will be “cam- action” and “electro-pneumatic”. The cam- action mechanism is the mechanism where the chucks and bit move frontward and rearwards on the alliance of rotation. Rotary hammer uses electro-pneumatic mechanism and in this mechanism, the piston of the drill does not touch the hammer. In this case, the energy comes from air pressure.
On the other hand, impact driver uses torque, which is the same movement needed to unscrew or screw toggles or fasteners. However, we know that screwdriver needs torque and also the forward motion to set up a screw. You may not face any problem but it is better to know the restriction of the impact driver.
You will find two types of impact drivers in the market and they are motorized and the manual. However, the outer sleeve of the manual driver is heavy which surrounds the inner core. When the hammer strikes the outer sleeve, torque produces and it applies to the screws.
Impact cam driver is more effective for Philips screw and not so effective for slot head screw. But the motorized driver can replace the screws with a great speed and large types of screws can replace with it.
The advantages of an impact driver
An impact driver is an essential tool. It gives a strong rotational movement and also uses a hammer. It is also used to loosen screw what need to be taken away. However, you are wondering what advantages the impact driver has over other drivers in the market. Now see the advantages below:
Unlike the usual drill or driver, the impact driver allows the user to drill into all kinds of materials. It also allows you to work with various kinds of screws. However, you can loose or tight the screws with the impact driver.
Impact driver provides high torque level. It also includes the unique hammering action. It functions by rotational action and strong hammering action. The two actions work such way that right synchrony is completed while working. Here, rotational action works on a certain point before hammering action works. So, the power gets more and you can work with additional freedom. The impact driver is very helpful while working with hard materials. Moreover, it has no tendency to break screw heads during working.
The structure of the impact driver makes your work easier. The motion of the driver and the drill are not connected directly, hence you need not high experience to work with it. You also need less force to exert during the work. So, there is no possibility of suffering from muscle strains during working with an impact driver.
The combination of driver and hammer let you work with only one hand. It is very helpful when you need to grip the work piece in place. Besides, you need not strain too much. It is very easy to control the impact driver.
What is a hammer drill used for?
Hammer drill is a regular drill. But the hammering action is additional here. In the most hammer drill, you will find a switch on the back part of the drill to activate it for hammering action. The only benefit of this drill is that it can drill concrete, stone and some similar substances. You can also drill wood, plastic, and some metals. It is good for house projects and woodwork.
Basic difference between impact driver and hammer drill
Now let us know the difference between an impact driver and hammer drill. In the case of the hammer drill, the hammering action applied directly to the drill and it creates hammering action. So, it works well on rocks and stone. So, you can use it to create the anchoring spot on concrete.
On the other hand, the force of an impact driver is delivered at the exact angle from the bloc of the drill. So, it is a rotational hammering action. We use it to loosen the screws or tighten them on wood. You can also use it to loosen the bolts of the machinery. The impact driver is good for lighter work than the hammer drill.
However, to use a drill impact or hammer, you need to learn the difference between an impact driver and hammer drill because they are the tools for different works. Before using them, test them properly if you do not use them before. The two tools are essential for some household works.
