Changing a disc takes just 3 seconds


With the new X-LOCK system from Bosch Professional, changing from 115 mm to 125 mm cutting discs and grinding discs is now up to 5x faster. The new changing system requires no additional tool, and no longer requires a flange, nut or spanner.

An X-LOCK disc is simply pressed into the mount on a compatible angle grinder. The hobbyist simply listens for the audible click to confirm the disc is properly seated. After finishing work, a user-friendly lever mechanism can then be used to remove the grinding tool quickly and easily.

In scenarios where different materials need to be worked on successively and a perfectly matched disc always needs to be fitted to the angle grinder, this system saves time and avoids hassle. This makes it the perfect tool for metalwork shops, plant construction and the plumbing trade.

The pros who work at Motopark Academy also rely on X-LOCK and RHODIUS when it comes to cutting and grinding work on their vehicles during servicing and car repairs. It’s all about performance – with no compromises made on precision or quality.

Grinding tools for pros – quality made in German


At a disc thickness of just 0.8 mm, the thinnest cutting disc now available for X-LOCK is a RHODIUS disc. The innovative flap discs from the pioneering RHODIUS VISION series are now also available for the patented BOSCH changing system.

The extra-thin RHODIUS cutting discs, RHODIUS flap discs and high-performance RHODIUS diamond cutting discs help users to keep cuts virtually free of burrs, offer impressively high stock removal performance with a long lifetime, and always ensure full power is available to users across a wide range of applications – from stainless steel, steel and aluminium to concrete, ceramics and natural stone.

The X-LOCK discs from RHODIUS in the diameters 115 and 125 mm are compatible with angle grinders from a wide range of manufacturers, such as Bosch, Makita, Berner and BTI.

RHODIUS plus X-LOCK – a double helping of industry-leading technology


At RHODIUS, we’ve followed one basic principle for nearly 70 years: we want to offer our users grinding tools that make working with metal easier and more efficient. So what could be more appropriate than to combine our outstanding performance-boosting technologies with an innovative tool changing system?

The XTK8 X-LOCK offers us a great example here: at just 0.8 mm wide, the disc simultaneously supports lightning-fast tool changing. The cutting disc cuts easily and creates very little tarnish colour while keeping burr formation to a minimum.

The development and production of this extra-thin cutting disc for 115 and 125 mm angle grinders posed a particular challenge. RHODIUS is the first manufacturer to have mastered this challenge and developed a production-ready disc. This is where RHODIUS offers premium Made in Germany quality.

X-LOCK for flap discs and diamond cutting discs


No quick-release flange or locking nut gets in the way when grinding metal or during other work. The angle grinder can be set at a very flat angle to the workpiece. This reduces the risk of scratches in the metal – and time-consuming reworking – to virtually nothing.

The changing system also offers another advantage when using diamond cutting discs. When used on an angle grinder with an 22,23 spindle, diamond cutting discs must be mounted the right way around (i.e. in the direction of rotation as indicated). So it’s easy to make mistakes when fitting the disc. But with X-LOCK, these mistakes are a thing of the past: the diamond cutting disc can only be fitted in one direction and the recesses on the cutting disc are always a perfect match for the mount. So the diamond cutting disc always rotates in the right direction.

All RHODIUS discs for X-LOCK are backwards-compatible. Which means they can also be used on a traditional angle grinder with an 22,23 mount.
Safety first, however: Always follow the safety instructions. Always wear the recommended protective equipment, never use a damaged disc and always use a closed protective hood when performing cutting work. Detailed safety instructions can also be found on the website run by oSa®, the Organisation for Safety in Grinding Tools, at www.osa-abrasives.org
