The Cordless Alliance System (CAS) is the first cross-manufacturer 18-volt battery system on the market. Since its introduction by Metabo in 2018, 50 brands from a wide range of trades have joined. Every one of the over 500 machines within the system are fully compatible – from classic power tools to specialised industrial products.
For professional users, this means fewer chargers, lower costs and unbeatable flexibility on the construction site and in the workshop. The powerful Metabo battery technology ensures high endurance and fast charging times – for cordless work far from the power outlet.







Without cumbersome cables, work can take place faster, with greater flexibility and in confined spaces – free of tripping hazards and with no need to hunt for power outlets. This increases efficiency and ensures a smoother workflow.

The CAS battery system uses cutting-edge technology from Metabo. For over 45 years, the manufacturer has been pursuing its vision of the “cordless construction site”. CAS batteries are developed in Germany and can withstand even the toughest working conditions.






Since 2018, right from the start, ROKAMAT has been a proud partner of the Cordless Alliance System (CAS) and actively contributes to the development of innovative, cordless solutions for the construction and trade industries.
This strategic partnership combines Rokamat's expertise in surface treatment with CAS's advanced battery technology to enable craftsmen and construction professionals to work with even greater efficiency and flexibility.
We will continue to promote the exchange of ideas and the development of new products that meet the needs of the industry.
