Real-World Pain Points Solved

1. Limited access to mains power on job sites

Construction and maintenance work does not always take place close to a convenient power outlet. Extension cords can also restrict movement and create additional handling issues.

This 20V cordless rotary hammer operates on a rechargeable battery platform, allowing users to work without being tied to a fixed mains power source. The two-battery configuration is especially practical for mobile installation and repair teams.

2. Standard cordless drills may not be suitable for heavier concrete drilling

A conventional cordless drill can handle many general drilling tasks, but heavier concrete and masonry applications require a tool designed for more demanding work.

With 990W rated power and a maximum drilling diameter of 28mm, this rotary hammer is intended for applications such as anchor-hole drilling, bracket installation, pipe support installation and other construction-related drilling tasks.

3. Frequent charging can interrupt continuous work

For contractors and installation teams, stopping work repeatedly to recharge a single battery can affect productivity.

This model includes two 20V / 4.5Ah batteries, allowing users to keep a spare battery available while another is being charged. The dual-battery setup is well suited to longer working sessions and mobile professional use.

Typical Applications

Construction

Suitable for drilling applications during building construction, renovation and installation work, particularly where mobility is required.

Concrete and Masonry Drilling

Designed for drilling applications involving concrete and masonry, including fixing holes for anchors, brackets and mounting hardware.

HVAC and Pipe Installation

Useful for creating mounting holes for pipe supports, brackets and related installation systems.

Electrical and Mechanical Installation

Suitable for drilling fixing points for cable trays, equipment brackets, mounting structures and other installation components.

Maintenance and Repair

The cordless format is convenient for maintenance tasks where power availability is limited or where operators need to move frequently between work areas.

Professional Contractor Use

The combination of two high-capacity batteries and a large carrying case makes the tool suitable for mobile contractors, service teams and professional maintenance crews.

Product Specifications

Two 20V 4.5Ah Batteries for Extended Working Flexibility

The standard configuration includes 2 × 20V / 4.5Ah batteries. This setup is practical for users who need longer cordless operation and want to reduce interruptions caused by charging.

For professional contractors, distributors and project buyers, a dual-battery package also creates a more complete retail configuration compared with supplying the tool with a single battery.

Large Plastic Carrying Case

The rotary hammer is supplied with a large plastic carrying case designed for practical storage and transportation.

The case helps keep the tool and accessories organized between jobs and provides a convenient packaging solution for distributors selling the product as a complete cordless power tool kit.

For wholesale orders, packaging details can be discussed according to target-market requirements.

B2B Wholesale and OEM Supply

This cordless rotary hammer is suitable for hardware wholesalers, power tool distributors, importers, contractors and private-label brands.

For B2B projects, the supply configuration can be discussed based on the target market and sales channel, including:

• Private-label branding

• Custom logo printing

• Customized housing colors

• Customized carrying case

• Customized product packaging

• Multilingual user manuals

• Accessory configuration

• Export carton configuration

• OEM / ODM production

For distributors building a cordless power tool range, battery compatibility and accessory configuration can also be discussed at the project stage.

What B2B Buyers Should Confirm Before Ordering

For professional importers and distributors, specifications beyond the headline power rating can have a direct impact on market positioning, after-sales service and customer expectations.

Before placing a bulk order, buyers should confirm:

• Battery cell specification and protection system

• Battery charging time

• Charger plug and certification requirements

• Tool holder / chuck specification

• Impact energy

• Impact frequency

• Product net weight and gross weight

• Concrete drilling capacity

• Available accessories

• Spare parts supply

• User manual language

• Product certification requirements for the destination market

• OEM logo, color and packaging requirements

These details should be confirmed according to the target market and final production specification rather than assumed from the nominal 20V or 990W rating.
