Frequently Asked Questions

Q: Which materials are these cutting discs best suited for?

These discs are specifically designed for cutting stainless steel (INOX), carbon steel, aluminum, cast iron, and other ferrous alloys, including rebar and structural tubing.

Q: What makes white aluminum oxide superior for grinding and cutting?

White aluminum oxide provides higher purity and sharper grains, which results in a cooler cut, reduced thermal damage to the workpiece, and a longer overall tool life.

Q: Are these discs compatible with all 4.5-inch angle grinders?

Yes, with dimensions of 115x3.2x22.2mm, they are compatible with almost all standard 4.5" electric angle grinders, air cut-off tools, and die grinders.

Q: What safety certifications do GRASSLAND abrasive products hold?

Our products are certified under MPA EN13743, ISO9001:2008, and ISO14001, ensuring they meet international safety and quality management standards.

Q: Can these discs be used for cutting stone?

While these specific aluminum oxide discs are optimized for metal, we offer specialized silicon carbide discs for stone applications to ensure the best performance and safety.

Q: What is the recommended safety gear when using these discs?

Always wear appropriate Personal Protective Equipment (PPE), including safety goggles, ear protection, and heavy-duty gloves, and ensure the grinder guard is properly installed.
