Impact Drill - One of the common applications of impact drill is to drive the screws. It performs this work with intense speed and power. Usually, it doesn’t have a key less chuck, but it uses a collet that works on hex shanked driver bits. It can drive even the longest and fastest screws with high efficiency. This drill proves to be an ideal option for driving thick screws into the hardwood and removing the stuck screws.

Pros of using Impact Drill -

  • It is preferred for safety and accuracy factor in any job.
  • It applies the constant torque throughout the process.
  • It is compatible with almost all types of drill and screw driving bits.
  • It can be configured with additional accessories like wire wheel brushes and rotary sanders.
  • To adjust the torque parameter, it has the option of the slip clutch.
  • It comes at an affordable price rate.

Cons of using Impact Drill -

  • It can stall when driving long and large fasteners.
  • Sometimes it can strip the screws that are getting a drive.
  • There is a possibility of bits loosening in the chuck.
  • It can put a strain on the user while using the device.

Rotary Hammer Drill - Rotary hammer drill can perform heavy tasks such as drilling and chiseling hard materials. It is used for hammering brittle materials and ensuring quick drilling with smooth operation. It provides a lot more impact on energy and has high durability. The rotary hammer is meant for larger jobs like drilling holes in hardened concrete materials. It can also be fitted with all sorts of other attachments. Few of its accessories include chisels for breaking metals, breaking concrete, etc.

Pros of using Rotary Hammer Drill -

  • The drill has 3 settings drill mode, hammer drill and just hammer mode.
  • It is a more powerful tool than other drill types. Thus, it can drill the holes larger than the one-inch diameter.
  • It possesses a large piston to produce a large amount of power.
  • It is one of the comfortable tools. Users can experience very fewer vibrations by using this drill type.

Cons of using a Rotary Hammer Drill -

  • Rotary hammer drill is bulkier and heavier.
  • It is usually very expensive to purchase.
  • As the tool mostly uses SDS chucks, the bit needs to screw into the chuck twice.

Conclusion:

Based on the features and pros & cons of the devices you can relate and analyse which device is more suitable for your job requirement. From this post, we get to know that a rotary hammer is an advanced version of the hammer drill. Thus, it is more powerful than the hammer drill and is mainly used in the construction industry. In comparison, the impact drill is generally used for driving or removing the screws, nuts and bolts. Also, it can be used as a regular drill, but in that case, the user needs to use hex shank drill bits.
