.An electric rotary hammer drill is a type of power tool that is used for drilling and chiseling concrete, masonry, and other hard materials. It is similar to a traditional hammer drill but with additional power and a specialized mechanism that delivers a rotary and hammering action simultaneously. This action allows the drill to break up harder materials more efficiently and quickly.
The drill is powered by an electric motor and is typically corded, though cordless versions are also available. It has a cylindrical housing that contains the motor and hammering mechanism, and the drill bit is inserted into the chuck at the front of the drill.
Some of the key features of electric rotary hammer drill include high power output, variable speed control, large torque, D-handle for greater control, and SDS chuck (slotted drive system) that allows for easy bit changes.
Overall, an electric rotary hammer drill is a powerful and versatile tool that is ideal for drilling and chiseling concrete, masonry, and other hard materials. It is commonly used in construction, remodeling, and DIY projects.

Different types of Electric Rotary Hammer Drill
There are several types of electric rotary hammer drills, including:
- Corded rotary hammer drill: This type of drill is powered by an electrical cord and is typically more powerful than cordless drills.
- Cordless rotary hammer drill: This type of drill is powered by a rechargeable battery and is more portable than corded drills.
- SDS-plus rotary hammer drill: This type of drill uses the SDS-plus chuck system, which allows for quick and easy bit changes.
- SDS-max rotary hammer drill: This type of drill uses the SDS-max chuck system, which is designed for heavy-duty applications and can handle larger bits.
- Rotary hammer drill with hammer only mode: This type of drill can operate in hammer mode only, which is useful for drilling into masonry or concrete.
- Rotary hammer drill with hammer drill mode: This type of drill can operate in hammer drill mode, which is useful for drilling into wood, metal or plastic.
- Brushless Rotary hammer drill: This type of drill uses a brushless motor which is more efficient than a brushed motor and has a longer life.
How does it work?
An electric rotary hammer drill works by using a combination of rotational and hammering motion to drill into hard materials such as concrete and masonry. The drill has a cylindrical chuck that holds the drill bit in place, and an electric motor that rotates the chuck and bit. The hammering motion is created by a piston that strikes the back of the drill bit, which provides additional force to break up the material being drilled.
When the drill is turned on, the electric motor rotates the chuck, which in turn rotates the drill bit. The hammering mechanism, which is connected to the electric motor, also begins to move up and down. As the drill bit rotates and the hammering mechanism strikes the back of the bit, the bit is forced into the material being drilled, breaking it up and creating a hole.
The hammering action of the rotary hammer drill allows it to drill into harder materials than a traditional drill, as well as providing a more efficient and faster drilling process.
What Should You Look Out for When Buying an Electric Rotary Hammer Drill?
When buying an electric rotary hammer drill, there are several factors to consider to ensure you get the best drill for your needs.
- Power: Look for a drill with a high power rating, measured in amps, to ensure it can handle heavy-duty drilling tasks.
- Chuck size: Consider the size of the chuck, which is the part of the drill that holds the bit. A larger chuck size will allow for larger drill bits and more versatility.
- Hammering action: Look for a drill with a high BPM (beats per minute) rating, as this will indicate a more powerful hammering action.
- Impact energy: Look for a drill with a high joules rating, as this will indicate a more powerful impact energy.
- Weight: Consider the weight of the drill, as a heavier drill can be more difficult to handle and may cause fatigue during prolonged use.
By considering these factors, you can find the best electric rotary hammer drill for your needs and budget.

FAQ about Electric Rotary Hammer Drill
What is the difference between a rotary hammer drill and a hammer drill?
A rotary hammer drill has a more powerful hammering mechanism than a traditional hammer drill. This allows it to deliver a higher impact energy per blow, making it more efficient in drilling into harder materials such as concrete and masonry.
Can I use a rotary hammer drill for regular drilling?
Yes, you can use a rotary hammer drill for regular drilling, but it is typically overkill for drilling into wood or metal. Rotary hammer drills are designed for heavy-duty drilling tasks, and are best used for drilling into hard materials such as concrete and masonry.
Can I use a rotary hammer drill with a regular drill bit?
Yes, you can use a rotary hammer drill with a regular drill bit, but it is not recommended. Rotary hammer drills are designed to be used with special SDS-plus or SDS-max hammer drill bits, which are specifically designed for heavy-duty drilling tasks.
