Frequently Asked Questions
Q: What grinder size are these 115mm sanding discs compatible with?
A: These sanding discs are designed for standard 115mm (4.5-inch) angle grinders with a 22mm arbor hole, which is one of the most common grinder sizes used in workshops, automotive shops, and metal fabrication environments.
Q: Can these sanding discs be used on both wood and metal?
A: Yes! The red steel paper abrasive construction makes these discs versatile enough for use on wood, metal, stainless steel, and other hard surfaces. Lower grits (P24–P40) are best for aggressive material removal, while higher grits (P80–P120) are ideal for fine finishing and polishing.
Q: Are these cross-hole sanding discs suitable for wet sanding?
A: These discs feature good water resistance, making them suitable for light wet-sanding applications. However, they are primarily designed for dry grinding and polishing tasks on grinder machines.
Q: How long do these sanding discs typically last?
A: Thanks to the wear-resistant red steel paper construction, these discs offer a long service life compared to standard abrasive papers. Longevity will vary depending on the material being worked, the pressure applied, and the operating speed of the grinder.
