Full details

The Bosch Expert Grout Segment Blade ACZ 85 RD4 is a professional-grade accessory designed for tilers, plumbers, and renovators who need a durable solution for cutting grout and abrasive materials. Featuring high-quality diamond grit, this blade delivers up to 10 times the lifespan of standard carbide alternatives, making it an ideal choice for heavy-duty mortar removal and cutting composite materials. Note that while this blade excels in abrasive environments, it is specifically optimized for soft tiles and grout rather than hardened stone or metal.

FAQs

Can I use this blade on granite or marble?

No, this blade is designed for soft tiles, grout, and abrasive composites; it is not suitable for hard natural stone.

How long does the blade typically last?

The diamond construction is designed to last up to 10 times longer than standard laser-melted carbide blades in abrasive conditions.

Does it fit non-Bosch multi-tools?

Yes, it is compatible with all Starlock-standard tools and most common oscillating multi-tools.

What is the grit size of the diamond coating?

The blade features a 40-grit Diamond-RIFF coating for efficient material removal.

Is the blade dishwasher safe or water washable?

While the blade is metal, we recommend wiping it clean with a dry or slightly damp cloth to prevent premature oxidation; do not put it in a dishwasher.

Troubleshooting

Blade feels loose or vibrates excessively

Ensure the Starlock interface is snapped in fully and the mounting head is free of debris.

Cutting speed has significantly slowed

The diamond grit may be clogged with material residue; clean the edge thoroughly with a stiff brush.

Blade won't fit the multi-tool

Verify if your tool is compatible with the Starlock system or if an adapter is required for your specific multi-tool brand.

Setup, Compatibility & Care

To install the blade, align the Starlock mount with your multi-tool head and press down firmly until you hear a click, indicating the snap-in mechanism is engaged. The blade is compatible with the Starlock system, which provides a rigid, 3D connection for optimal efficiency. After use, inspect the diamond grit for material buildup. You can clean the blade by using a soft brush to remove residual mortar or dust. Store the blades in the provided plastic case to prevent damage to the diamond edge between jobs.
