SDS hammer drills are quite similar to regular hammer drills with the exception that they are much stronger. These drills are very powerful and can be used to drill holes through any type of material. Unlike a regular drill that drills through rotational forces, a SDS hammer drill blows into materials such as bricks and concrete.
SDS hammer drills operate in three modes: drill only mode, hammer only mode, and drill and hammer mode. The drill only mode is used for any drilling and unscrewing need while the hammer only mode is used to chip off unwanted parts or to fragment materials. When SDS drills are used in the drill and hammer mode, they are the most lethal. Both modes work together to create a simultaneous hammering and drilling effect that can be used to drill through the hardest material.
The advantage of SDS hammer drills over regular drills is that they significantly reduce the time and strength needed to drill through hard surfaces. SDS hammer drills provide home users with flexibility and efficiency. Although they are larger than regular drills, they do a quicker job especially when it comes to breaking through bricks and concrete.
Bosch was the first to invent SDS hammer drills and to introduce them to the market. However, SDS hammer drills can be easily found and purchased at any warehouse or retail store that sells mechanical tools.
When buying SDS hammer drills, you need to make sure that you purchase one that has a safety clutch. This is very important. These drills are very powerful and if something goes wrong during the drilling process, you can encounter serious injuries if the SDS hammer drill that you are using does not have a safety clutch. Some SDS hammer drills only have one mode. Based on the type of work you will be using it for, you will have to decide if you need a SDS hammer drill with one mode or both modes. You would also need to take the weight and the overall power of SDS hammer drills as well as the warranty and prices offered by different vendors into consideration when buying SDS drills.
