The idea of buying a cordless drill may arise any doubts or perceptions for that matter until it comes to deciding on what type of a drill you should buy. To most people, especially the first time buyers, drills may look quite similar by just looking at them, unknown to them is that they are way too different when it comes to the tasks they are designed to carry out. Going through cordless drill reviews guarantees to offer some knowledge about the same. So then what kind of drills are you supposed to buy? Let us look at some of the main types of drills.
Types of drills
- Drill driver: Drill drivers are the tools to go for if you are the type of person to only engage in simple drilling tasks that do not require too much sweaty action. They are most common among many household and come in handy for holes drilling in everything to do with walls, wood and drive screws. Their weight is manageable making them more effective for awkward to reach positions compared to heavier drills because most tasks require you to lift up your hands way above the head. Despite all the positive reviews about drill drivers, it is fair to say that they cannot manage tougher jobs since they do not have powerful motors.
- Impact driver: These type of drills are designed to drive screws mostly and not the usual hole drilling. They usually involve a combination of huge spinning torque and striking blows against the back side of the driver bits to powers screws into the toughest working surfaces. There is no much back and forth motion when it comes to working with this tool as compared to other tools such as SDS drills and hammers, not forgetting to mention that they are not usually hard on the wrists. It is also of importance to note that with an impact driver you do not need to drill a guide hole for screws because it is powerfully designed to do the job on its own without relying on any guide on where to drill or not for that matter.
- Combo drill: A combo drill is what you really need if you are into tougher materials such as concrete or even metal. They can handle any type of drilling and screw driving tasks and they provide improved torque for most demanding jobs and also include a few hammer involvement situations to help break through hard materials. They are more expensive compared to some standard drill tools.
- Hammer drill: These types of drills use more powerful forwards and backwards hammering action, with combined spinning drill bit which facilitates a successful strike through the toughest masonry or stone. That means that with a hammer drill, you should expect a bigger and bulkier drilling tool which of course is more costly compared to basic drills counterparts. You should also know that they are not friendly when it comes to your ears for they tend to be quite noisier.
- SDS drill: These tools which are also referred to as SDS rotary hammers are even bigger and bulkier compared to the standard hammer drill. They are usually designed for heavy duty jobs and that means a lot of power is key. The drill and driver bits are designed with small indentations at the back where they usually slot into the drill way too fast since there are no chucks required here, and they are held securely in place by the ball bearings in the SDS chuck, all this while hammering the bit back and forth. These drills usually exist in three main types; two-mode, three mode drills and finally three modes with interchangeable chuck. For the two-mode drills, you can only choose between rotary only and combined rotary or hammer action while the three modes have the option of hammer only action.

Soft clothing can clean the visible dirt while an air compressor can be used to blow away dust particles from the motor.
