2025-07-22

A cordless rotary hammer drill is a versatile and powerful power tool that combines the functions of a traditional drill with a hammering action, all without the constraint of a power cord. Here is a detailed introduction:

Features

Power Source: Usually powered by rechargeable li-ion batteries. For example, the ETBRH01-26 SDS Plus cordless rotary hammer drill is equipped with a 21V/4.0Ah li-ion battery, which provides the tool with sufficient power and has the advantages of high energy density and long lifespan.
Motor: Many cordless rotary hammer drills use brushless motors, Its brushless motor has a no - load speed of 1,100 rpm and an impact rate of 3600bpm, offering high - efficiency power output and a longer service life.
Chuck System: Commonly equipped with an SDS-plus chuck, which can quickly and easily replace drill bits.
Function Modes: Generally has multiple function modes. For example, our cordless rotary hammer drill has four functions: drilling, hammer drilling, hammering, and chiseling, and it is equipped with an easy - to - use side - mode selector, which can meet different construction needs on concrete, metal, etc.
Auxiliary Equipment: Often comes with a 360 - degree auxiliary handle and a depth gauge. For instance, our ETBRH01-26 SDS Plus cordless rotary hammer drill has these accessories, which can help users better control the drilling direction and depth and improve work accuracy. Some models are also equipped with built - in LED lights to facilitate work in low - light environments.

Advantages

Portability: Without the limitation of a power cord, it is very convenient to use in outdoor work, areas without easy access to power sockets, or large - scale work areas, enabling users to move freely.
High - efficiency in Drilling: The combination of rotation and hammering can quickly drill holes in hard materials such as concrete, brick, and stone, which is much more efficient than traditional drills.
Versatility: It can not only be used for drilling holes but also for chiseling operations, such as removing old tiles, knocking down part of the wall structure, etc., with a wide range of applications

Applications

Concrete Drilling: It is mainly used for drilling holes in concrete walls, floors, etc. For example, when installing curtain rods, wall - mounted shelves, or electrical conduits in concrete structures, a cordless rotary hammer drill can quickly and accurately complete the hole - making job.
Masonry Work: Suitable for drilling and chiseling operations on bricks and other masonry materials, which is very useful in building construction, renovation, and other projects.
Wood and Metal Drilling: Not only being used on hard materials, it can also be used for drilling holes in wood and metal.
