When it may not be suitable
This pad is specifically optimized for hard natural stones like granite and marble and may not be suitable for softer materials such as wood, plastic, or soft metals, as the diamond grit may cause excessive damage or clogging.

How to use
Attach the polishing pad to the velcro backing plate of your angle grinder, ensuring it is centered correctly to prevent vibration. Begin the grinding process at a moderate speed, applying even pressure across the surface. For optimal results, move the tool in a consistent pattern to ensure uniform material removal. After completing the initial pass with the 50-grit pad, proceed to finer grit pads in sequence to achieve the desired level of smoothness and finish.
What to consider before purchase
Ensure your angle grinder supports a 125mm diameter accessory.
Verify that your project requires a 50-grit abrasive for the initial stage.
Consider purchasing a full set of grits to achieve a professional polished finish.
Usage recommendations
For the best results, it is recommended to use the full range of polishing accessories, starting from the coarsest grit (50) and progressing to the finest (3000). To achieve a high-gloss effect, finish the process using dedicated BUFF overlays.
