The "Net Grinding Disc" term, particularly with the "3S" designation, suggests a modern abrasive technology that may incorporate a net-like or mesh structure for the backing and/or abrasive grain. This design is often associated with:
Improved Dust Extraction: Allowing material to be ground and dust to be removed more effectively, leading to a cleaner work area and reduced clogging.
Uniform Wear: The mesh structure helps maintain a consistent grinding surface.
Safety: The net reinforcement contributes to the wheel's stability.
It is a multi-purpose grinding disc designed for users who need to work on a variety of different metal types, including ferrous (steel, stainless steel) and non-ferrous (aluminium) materials, with a focus on speed and cost-effectiveness.
