Cordless tools have rapidly become the standard on modern jobsites, but not all battery platforms are created equal. Many installers find themselves juggling different chargers, incompatible battery sizes, slow charge times, and inconsistent power from tool to tool. The Cordless Alliance System, also known as CAS, is changing that problem entirely. With a single battery platform that powers hundreds of professional tools across dozens of brands, CAS is becoming one of the most important innovations in the professional tool market.

Now that major tile-industry manufacturers like Rubi have joined the CAS ecosystem, tile contractors finally have access to a truly unified cordless solution built for demanding installation work. Below, we break down why CAS matters, how it works, and why this battery platform is quickly becoming the future of cordless tile tools.

What Is CAS and Why Tile Installers Should Pay Attention

CAS is a shared 18 V battery platform developed in Germany and supported by over 45 professional-grade tool manufacturers. The idea behind the system is simple. Instead of being locked into a single brand for all of your cordless tools, CAS lets you use one battery type across hundreds of tools, regardless of manufacturer.

For tradespeople who rely on consistent, high-performing cordless tools, CAS eliminates the complexity of maintaining multiple battery systems. It brings stability, power, and cross-brand flexibility together in a way that no other battery platform currently offers.

Rubi’s Adoption of CAS Signals a Major Shift for Tile Pros

One of the biggest breakthroughs for the tile industry is that Rubi, a global leader in tile cutting and installation tools, has now moved to using CAS batteries. This is a major development, because it places Rubi tools on the same platform used by Metabo, Mafell, Eibenstock, Collomix, Fischer, Eisenblätter, and many other high-end European manufacturers.

With Rubi onboard, tile professionals now gain access to a cordless ecosystem where one battery can power cutters, grinders, mixers, polishers, and additional tools from dozens of brands. Tile ProSource will be at the front of this movement, offering CAS-powered Rubi tools as the platform expands in the coming months.

One Battery for More Than 400 Professional Tools

The biggest advantage of CAS is its scale. The platform supports:

• More than 45 professional brands

• Over 400 compatible tools

• One unified 18 V battery system

For contractors, this means a single battery type can run dozens of tools across multiple categories and brands. Installers no longer need several chargers, a drawer full of incompatible battery packs, or different tool lines just to stay cordless.

This reduces jobsite clutter, lowers long-term investment costs, and improves logistics for contractors managing multiple crews or work trucks.

Why CAS Delivers Better Performance Than Standard Battery Systems

Performance is where CAS separates itself from most cordless platforms. It uses advanced cell technology and engineering that is specifically designed for professional environments and continuous jobsite stress.

Advanced LiHDX Cell Technology

CAS batteries use “tabless” LiHDX cells that offer several benefits:

• Lower internal resistance

• Reduced heat generation

• Higher sustained power output

• Longer runtime before needing a charge

This means more consistent torque and smoother operation, especially on high-draw tools like grinders and mixers.

Designed for Demanding Jobsites

CAS batteries are engineered and manufactured in Germany to withstand real-world professional abuse. Tile, masonry, and construction environments expose tools to heat, dust, vibration, and moisture. CAS is built to maintain performance under these conditions without premature battery degradation.

Reduced Downtime and Fewer Battery Swaps

Tile installers who use grinders, mixers, and battery-powered cutters know how quickly standard cordless batteries can drain. CAS is built to minimize interruptions, giving pros more cutting time and faster workflow on porcelain, stone, and slab materials.

Why Tile Pros Benefit Most from CAS Technology

Tile installation requires precision, stability, and reliable torque across long cuts and heavy materials. CAS helps solve many of the challenges cordless tile installers face.

More Runtime on Grinders and Cutters

The high-efficiency cells in CAS batteries help power tile grinders and saws with fewer drops in performance, especially during continuous porcelain cutting.

Cross-Brand Flexibility

One CAS battery can be used on tools from multiple manufacturers, which reduces clutter and the cost of maintaining multiple tool systems.

Better Control and Lower Heat

LiHDX technology produces less heat under load, giving tile pros more consistent torque and smoother cutting action on dense porcelain and ceramic.

Fleet Simplification

For contractors with multiple installers, using one battery platform reduces fleet management costs and increases tool compatibility across teams.

CAS Is the Future of Cordless Tile Tools

With Rubi joining the CAS ecosystem and other manufacturers expected to follow, tile professionals now have access to a unified cordless system that delivers stronger performance, longer runtime, and unmatched flexibility. Instead of being forced into a single brand, contractors can choose the right tool for the task while keeping a single battery platform.

Tile ProSource is committed to helping professionals adopt CAS and stay ahead of industry changes. As CAS-powered tools begin to roll out, we will be stocking the newest cordless solutions that give installers more freedom and better performance on every job.
