7. SDS Rotary Hammer Drill – This is a type of rotary hammer which uses a special SDS shank bit system.

Best Corded Hammer Drill

There are several factors which you should consider before choosing a corded hammer drill. These are:

Length of the power cord – If you work in a large area and there are no electrical outlets close by, you need a corded hammer drill which has a long power cord. This will allow you to work anywhere in the room or in the house without having to change the plug.

Number of speeds – The speed of rotation of any drill is measured in RPM or revolutions per minute. Most corded hammer drills come with two to three adjustable speeds. The more speeds it has, the more versatile it is. Capacity of the gear box – The gear has to do with the power of the drill which is transferred to the tip of the tool. For most corded hammer drills, the capacity of the gear ranges from 10 to 30 amps. Larger capacity means more power and torque but also larger and heavier tools.

Size and Weight – A lighter corded hammer drill is easier to control and operate for long hours.
