Product Description

The electric hammer is a multifunctional electric tool that combines rotation and impact force. It is mainly used for efficient drilling or chiseling on hard materials (such as concrete, masonry, stone, etc.). The following are its main functions and features:

1. Core function
Drilling (with impact)

Suitable for hard materials such as concrete, brick walls, stone, etc.

More efficient than ordinary electric drills through high-frequency hammering + rotation action.

Common hole diameter: 6-40mm (depending on power).

Chiseling (impact only)

Demolition, grooving, chiseling walls or floors.

Replaceable chisels (flat chisels, pointed chisels, etc.) for demolition operations.

Rotary drilling (no impact)

Drill holes in wood and metal like ordinary electric drills (impact function needs to be turned off).

2. Additional functions (supported by some models)
Speed switch
Adjust the speed to adapt to different materials or operation requirements.

Forward and reverse switching
Convenient to exit the drill bit or adjust the operation when the drill is stuck.

Safety clutch
Prevents the reverse torque from hurting your hand when the drill is stuck.

Shock-absorbing design
Reduces fatigue caused by long-term work.

3. Typical application scenarios
Install expansion bolts and anchor bolts (such as air conditioners and bracket fixation).

Wall grooving during water and electricity renovation.

Removal of tiles and concrete blocks.

Garden construction (such as drilling holes in stone slabs).

4. Differences from related tools
Tool type Functional features Applicable scenarios
Electric hammer Impact + rotation, strong force Concrete, stone drilling/chisel
Impact drill Small amplitude high-frequency impact, weak force Brick wall, lightweight concrete
Electric pick Pure impact, no rotation (high-power chiseling) Demolition, trenching
Hand drill Only rotation, no impact Wood, metal, plastic drilling
5. Precautions
Personal protection: Wear goggles and dust masks to avoid debris splashing.

Drill bit selection: alloy drill bit for concrete, twist drill for metal/wood.

Avoid idling: Do not turn on the impact mode when there is no load to avoid damaging the internal mechanism.

Regular maintenance: clean the carbon brushes and add lubricating oil (according to the instructions).
