What is the difference between hammer drill and a regular drill

When they are used on smaller and lighter screws, the impact driver will use the rotary power of the motor to drive the screw forward. In this sense, they operate a lot like any other power drill or driver. When the maximum force provided by the motor is not sufficient, the hammering mechanism actuates.

The hammering action primarily takes place in the direction of rotation resulting in higher torque output. Because it uses both rotary power and percussion power, an impact driver is sort of a mixture of both a hammer drill and a regular power drill. The hammer drill and impact driver differ in three key aspects; the purpose, design and working principle. The main difference between a hammer drill and an impact driver is what they are used for. You will go for a hammer drill when you need to drill holes into tough materials like concrete.

You use an impact driver when you want to rusted or over-torqued screws and to drive screws into a tough material. If you just need to drill into wood, just go for a regular, inexpensive power drill.

In terms of appearance, the two drills look similar, but upon closer inspection, you will notice some key differences. Hammer drills have a longer barrel and are just bigger in general.

On the other hand, impact drivers tend to be stubbier, especially around the barrel. Another key difference is that hammer drills have a 3 jaw chuck for those who are unfamiliar with the term, a chuck is essentially the front part of the drill, where bits are held.

The rotary hammer drills which are much more powerful usually come with SDS chucks. Where they prove less effective is on wood and metal drilling tasks or screwdriving , and it is rare to find SDS bits that are designed for anything other than masonry.

However, on most models the hammer mode can be switched off and some are supplied with interchangeable jawed chucks which make them suitable for use with all straight shank accessories as well.

SDS drills are well worth looking into if you primarily need to drill into bricks or concrete, and they are the only type of machine in this list that can be used for chiseling as well as drilling. Corded SDS drills may be available in v — for use with standard mains sockets, or v — for use with step down transformers.
