An impact driver is a tool used to tighten the screws that need more torque than a traditional screwdriver can provide. It is also used for loosening up corrosively frozen or over-torqued large bolts and nuts.
Impact drivers also function as effective drilling tools and can easily use big bits for boring large holes. They generally produce more torque than your normal drill. If you are looking for a tool specifically for drilling, a normal drill, or a hammer drill is a better option. Hammer drill provides more control while drilling into tough surfaces like concrete. Nevertheless, an Impact driver has a lot of applications that make it a good investment.
In manual impact drivers, the inner core is splined to the heavy outer sleeve. When the outer sleeve is struck with a hammer, the downward force on the spine produces a turning force to the core or the work bit or socket attached to itThe heavyvy rotational inertia of the sleeve is to the lighter core by the tool to generate a lot of torque. The cam out is reduced or even eliminated as the hammer blow forces the drivers down into the screw.
A cordless impact driver consists of an Anvil, Motor, Screwdriver bit, Speed control trigger, a gearbox, and a battery pack. In a cordless impact driver, electrical current from the battery is transferred to the motor through the speed control trigger by a switch inside the tool. The battery’s electrical current is converted into rotational energy by the motor which turns the chuck. The torque and speed combine to make power, which is measured in watts.
Now, the motor’s power is transferred through the gearbox to a hammer and anvil mechanism. In case there’s need of high torque, the hammer strikes the sides of the anvil which delivers a strong rotational force to the screwdriver bit to help drive in the screws.
Impact driver is a great tool for any professional or DIY enthusiast. you can use an Impact driver for your home projects. It can also be used for drilling. Before buying an Impact driver, you can consider the following things –
Generally, Impact driver produces a lot of toque. More torque means easier handling for you. It also ensures faster and effective functioning of the tool. Different models provide different speed settings to give you more optimal control for different tasks.

When it comes to Drills, there are all these different options available to the users, i.e., hammer drills, rotary hammer drills, etc., and these too come in different types such as SDS, SDS+, SDS max, etc.
You must be wondering what that stands for, and what it means when the product has SDS or SDS + along with its title. But, whatever you end up buying, it has to be right for your project.
Finding the right SDS Rotary hammer drill can be a real task with so many great options available in the market. However, if you’re aware of your own needs, it’s not that hard.
Determining your needs entails assessing the projects you mostly need the drill for, and the complexity they present. You also need to identify trustworthy manufacturers, and which one of the products that these sources have available fit your requirements. You don’t want to go overboard, but you also don’t get something that might fall short on output. You also need to aware of factors like design, specifications, special features, type (cordless, corded)(SDS, SDS- Plus, SDS Max), and so on, among other things.
In this article, we’re going to discuss the best of SDS Rotary Hammer Drills available for you in the market at the moment. Between the various options, you can figure out which is the right option for you. Before you can make the final judgment, let’s explore what it all means.
When you see a Hammer drill, or Rotary (Hammer) Drill with SDS along with its name, in this context, SDS stands for Special Direct System. Developed by Bosch in 1975 for hammer drills, it’s a system that is compatible with a cylindrical shank called SDS shank. SDS bits have indentations, which fit the chuck, and it goes on to the chuck, which holds the tool until released.
The diameter of an SDS shank 10 mm. SDS shanks and chucks are compatible with Hammering mechanisms of the masonry drills and are ideal for heavy-duty tasks, like drilling stone and concrete.
SDS bits come in standard sizes, which are as follows.
These two types are popular among users. Other than these, there’s also SDS Top, a 14 mm shank, which is not as common.
But the question remains. Why consider SDS at all? Let’s see.
In ordinary Drills, the functioning capability is limited, but for machines that have the hammering mechanism, an SDS bit can take the overall action to the next level.
SDS bits complement the tool in a way to make the task more efficient, meaning less energy and time spent on finishing up that particular project.
Now, since the SDS bits come in different sizes, users need to assess their needs to determine the right solution for them. Drills that support SDS Plus are ideal for comparatively lightweight applications, then SDS Max bits.
Still, SDS is a better choice if you require hammering action for your projects, as SDS bits compliments the tool in such a way as to optimize the hammering action and the overall performance.
Bosch is one of the recognized power tool manufacturers, bringing you quality options in the SDS Rotary Hammer Drills. This option from the company is also something you should consider. It is an SDS Rotary hammer that offers you multiple modes to choose from when you’re operating. It is a powerful option and is a well-received product in the market.
