Frequently Asked Questions
No, stone cutting discs must never be used for grinding. They are designed exclusively for cutting and must always be presented to the workpiece at a 90-degree angle.
These specific discs are ideal for masonry, stone, concrete, and non-ferrous metals, utilizing Silicon Carbide for effective abrasion.
MPA certification ensures the disc has passed rigorous safety and quality tests, conforming to European safety standards (EN12413) to protect the operator.
The maximum working speed for this disc is 80 M/S. Always ensure your tool does not exceed this limit for safety reasons.
We offer grit sizes 24#, 30#, 46#, and 60#. Generally, lower grit numbers are for coarser, harder materials, while higher numbers provide a smoother finish.
Avoid applying excessive pressure; let the disc do the work. Maintain a strict 90-degree angle and ensure the disc is properly mounted on a compatible arbor.
