Frequently Asked Questions
Silicon Carbide is harder and more brittle, making it ideal for non-ferrous metals, glass, marble, and stone, whereas Aluminum Oxide is typically used for ferrous metals like steel.
For heavy stock removal and initial shaping of stone or concrete, we recommend coarser grits such as 40# or 60#.
Yes, these discs are specifically designed for use with hand-held angle grinders, featuring standard arbor sizes for easy mounting.
They are highly effective on marble, granite, concrete, building materials, and various non-ferrous metal alloys.
The hardness grade indicates the strength of the bond; "R" is a standard grade that balances the rate of abrasive wear with the efficiency of material removal.
Absolutely. We offer comprehensive OEM services including custom grit specifications and private label packaging for global distributors.
