Frequently Asked Questions
What RPM rating is recommended for this 5-inch fibre disc?
While specific RPM ratings vary by angle grinder model, ensure your grinder's RPM does not exceed the disc's maximum safe operating speed, typically indicated on the disc or its packaging.
What type of safety equipment is required when using this disc?
Always wear appropriate personal protective equipment (PPE), including safety glasses or a face shield, hearing protection, and sturdy gloves, when operating an angle grinder with this disc.
Can this disc be used for fine finishing?
No, the 36-grit abrasive is designed for coarse material removal and surface conditioning, not for fine finishing. Coarser grits are used for initial stock removal and shaping.
What is the backing material of this disc?
The backing material is a strong, flexible fibre, which provides durability and support during grinding operations.
How does this 36-grit disc differ from finer grit options?
The 36-grit disc is significantly more aggressive, designed to remove material quickly. Finer grit discs are used for smoother finishes and less demanding surface preparation.
