Frequently Asked Questions

Q: What angle grinders is this zirconia flap disc compatible with?

A: This 4.5" (115mm) double-side flap disc with a 22mm arbor hole is compatible with most standard 4.5" angle grinders. Always verify your grinder's maximum RPM rating — this disc is rated up to 15,300 RPM, so your grinder must not exceed that speed for safe operation.

Q: What is the difference between the available grit sizes (P40, P60, P80, P120)?

A: P40 is the coarsest grit, best for heavy-duty stock removal and aggressive rust or scale removal. P60 and P80 are medium grits ideal for general grinding, blending, and de-burring. P120 is a finer grit suited for smoothing and surface finishing work. Choose a lower number for fast material removal and a higher number for a smoother finish.

Q: Can this flap disc be used on materials other than metal?

A: Yes! While the zirconia alumina abrasive excels on metal and stainless steel, this disc is also suitable for grinding and finishing wood, stone, and plastic surfaces, making it a highly versatile addition to any workshop.

Q: What makes the double-sided design better than a standard flap disc?

A: The double-sided design allows the disc to grind on both faces, enabling it to reach into narrow grooves, slots, and gaps that a conventional single-sided flat wheel cannot access. This makes it uniquely effective for profile grinding and working in confined areas.
