Hammer Drills are equipped with a masonry bit and are usually designed to drill into concrete, stone, brick or mortar.
Best Cordless Hammer Drills
During its operation, the hammer drill rotates normally like a drill and at the same time has a forward and backward hammering action. Hammer drills are available in both corded and cordless form. The rotary hammer is a very specialized kind of a hammer drill which is dedicated and is considered a specialty tool.
It is required only when there is a lot of masonry work to be done. related drilling. For a DIYer, however, this would be too much expense and redundant capability. The regular Cordless Hammer drill should be fine for him/her. In case, there is an electrical outlet present whenever work needs to be done, a corded drill with a hammer option is usually enough. However, when work needs to take place at locations away from the electrical outlets, a cordless hammer drill is the best option available.
The cordless hammer drill action is currently found on a plethora of drills. In the beginning, when the hammer action was added to cordless drills, the movement of the hammer did not carry sufficient power and thus, it was not the kind of feature that could be relied upon. However, with time, as the power cell technology has made significant improvements and cordless batteries are now getting more popular than ever and gaining esteem as well.
Therefore, while it is true that traditionally, people were more prone to purchase corded drills,however, the popularity of cordless drills has now overtaken the one for the corded ones.

The Hammer Action
With the help of hammer action, the worker is able to drill holes into stone as well as any other kind of masonry type of material fairly easily. While the drill is rotating, the drill bit, as well as the chuck, is pushed in the forward direction by a spring. This spring sits on the eccentric flange inside the gearbox of the cordless drill.
This, in turn, produces a ‘forward and backward’ kind of movement which is the equivalent of a hammer action. When a hammer action takes place in a drill, the drill bit spins around and punches up and down very fast into the material as well. The bit does not move much. perhaps a fraction of an inch,however, the short but fast blows end up increasing the force and therefore, it becomes possible to drill even in extremely hard materials such as masonry.
The Cordless Feature
The cordless feature of the hammer drill stems from the fact that there has been a great enhancement in the technology related to power cells in the last so many years. Moreover, the batteries for such equipment are now very popular and people usually prefer cordless devices which can be charged to corded ones which cannot be taken too far away from an electrical outlet despite the high level of power output capability they have. This dreams that the cordless hammer drill can be taken to where the work needs to be done rather than forcing the work done to come near to the tool as in the case of a corded tool.
The cordless drills can be used in a variety of different ways. These drills are able to easily drill holes up to 1/2″ which are small holes in a variety of different type of masonry materials. The greatest advantage is that the workers do not need to acquire a separate corded hammer drill for boring only a few holes at a site. The cordless hammer drill comes in handy and is more than good enough for this kind of job.
The user needs to be cautious,however, about a few factors that are important when it comes to the use of the cordless hammer drills. As far as the design of the cordless hammer drill is concerned, the chuck gets to be pushed in the forward and backward directions thereby producing the hammer action. This movement which is additional to the chuck of a cordless hammer drill ends up giving a larger run-out or wobble.
This can, in some cases at least, lead to a dropin precision for the cordless hammer drill as a power tool. The addition of a hammer action to the cordless drill also leads to an increase in the overall weight and the length of the power drill which might not be the desired feature for many people,however, for those who really require hammer action as a part of their cordless drill, this is indeed a great feature despite the increase in weight and length of the tool as they would usually require this action for their routine jobs.
(we have also written a comprehesive guide about the Best Laser Levels).
Cordless Hammer Drill and the Cordless Pneumatic Hammer Drill
Some people have a preference for the cordless pneumatic Hammer drill. The cordless pneumatic Hammer drill uses mechanical action to push the drill bit forward by utilizing a mechanical piston. However, such drills are only required if a very force is required to bore very large or deep holes in materials such as concrete and other stone types of materials as such equipment utilize the pneumatic movement to do so. The professional cordless pneumatic hammer drills range from 18 V to 24 V and all the way to 36 Volts. On the other hand, the rotary hammers allow both drill bits and chisel to be used in them.
Ways to rate the Cordless Hammer Drills
There are many ways to rate the cordless hammer drills. The torque produced by these drills is a good criterion. Other criteria can include the battery power vs. the performance exhibited by these drills especially when they are subjected to tough jobs like requiring to drill holes in concrete. Moreover, the drills can also be rated in terms of the ergonomic nature of their design which enables the user to grip these with ease while the drill is working.
The cordless drills can handle very tough jobs as well. Most of the operators do require drilling in concrete beside drilling in much softer materials like wood or drywall which could even be accomplished with a drill/driver, etc. Concrete drilling can test how many holes the hammer drill is able to do and the time taken to drill these. Normally, it has been observed that the brushless hammer drills have a long battery life however, this decreases if concrete drilling is carried out.
Not to be used for screws
The Hammer setting on the cordless hammer drills is not supposed to be used for drilling screws. An impact driver is required to do that. The impact driver uses an impact type of action to give a boost to the rotational drive. Rotational impact drivers are used for driving in screws, nuts, and boots, lags but do not do the drilling work. For drilling Impact, drivers should never be used.
The right tool to use is a corded or cordless hammer drill. If the drill work has to be performed at places where the electrical outlets are either not available or far, the cordless hammer drill would be the right tool to choose. The cordless hammer drill,therefore, is the right choice for a large number of people who carry out drilling tasks at different locations.
