CEDIMA STB ULTRA 125 mm diamond grinding wheel is a 125 mm abrasive disc for compatible angle grinders and power grinders. Designed for high-performance material removal and surface preparation, the diamond-bond construction delivers consistent cutting action and extended tool life. The wheel is intended for work on concrete, natural stone, ceramic tiles, mortar joints and similar mineral surfaces, offering durable performance for professional construction and renovation tasks.
Advantages
The diamond bond and abrasive grit combination provide durable wear resistance and stable cutting speed over prolonged use. Its 125 mm diameter and balanced design allow controlled removal rates while maintaining surface flatness. The disc is engineered to resist glazing and maintain consistent profiling, which reduces downtime for frequent replacement and supports predictable finishing results.
Suitable for
- Grinding and leveling concrete surfaces and screeds
- Removing thin-set, mortar residues and adhesive traces
- Profiling and dressing stone edges and architectural details
- Surface preparation before coating or tiling
- Use with compatible 125 mm (5") angle grinders and power grinders
When it may not be suitable
This diamond grinding wheel is not intended for use on metal, wood or other non-mineral substrates; using it on inappropriate materials will reduce performance and can damage the tool. It is also not designed for wet grinding; operating it in conditions with excessive water can impair bond integrity and increase safety risks.
Key specifications
- Diameter: 125 mm
- Suitable machine type: handheld angle grinders and power grinders compatible with 125 mm discs
- Abrasive type: diamond bond abrasive for mineral materials
- Primary applications: material removal, surface preparation, edge profiling, dressing
- Typical substrates: concrete, natural stone, ceramic tile, mortar
How to use
Fit the grinding wheel to a compatible 125 mm grinder following the machine manufacturer’s mounting instructions and safety requirements. Use appropriate personal protective equipment including eye protection, gloves, dust mask/respirator and hearing protection. Start at low to moderate speed and apply steady, even pressure; avoid excessive force that can overheat the bond or accelerate wear. Work in overlapping passes for even material removal and periodically inspect the wheel for wear or damage. Allow the tool to cool between extended runs if necessary.
What to consider before purchase
- Confirm compatibility with your grinder’s disc diameter and mounting type
- Verify that the primary work materials are mineral-based (concrete, stone, tile, mortar)
- Ensure availability of appropriate PPE and dust extraction for dry grinding operations
- Consider required grit/coarseness for the desired removal rate and surface finish
Usage recommendations
Use the wheel for controlled, dry grinding on mineral substrates with progressive passes rather than aggressive single cuts. Combine with effective dust extraction and appropriate respiratory protection to maintain a safe working environment and extend wheel life.
