In short: These 115 mm corundum fiber grinding discs are designed for use with angle grinders when working on metal, steel, stainless steel, concrete, or old coatings to achieve controlled material removal. The 50-pack is ideal for workshops, construction sites, metal fabrication, and regular renovation projects.
Fiber discs are used with a compatible backing pad. This allows them to work more directly and aggressively than many flexible abrasives, making them a particularly good choice if you're looking for grinding discs for angle grinders, 115-mm fiber discs, or grinding discs for metal.
| Diameter | Ø 115 mm |
|---|---|
| Abrasives | Corundum / Aluminum Oxide |
| Organizer | Vulcanized fiber backing for consistent material removal |
| Grit sizes | K16, K24, K36, K40, K50, K60, K80, K100 |
| Package Size | 50 pieces |
| Use | Metal, steel, stainless steel, concrete, non-ferrous metals, existing coatings |
Suitable for angle grinders with a 115 mm disc mount in combination with a compatible fiber disc backing pad, e.g., Bosch Professional GWS 115, Makita GA4530/GA4540, FEIN WSG 7-115, and comparable 115 mm angle grinders. Always check the backing pad, permissible disc diameter, speed, and machine manual.
| grit | Recommended Use |
|---|---|
| K16–K24 | Rough removal, rust removal, old coatings, and significant material removal. |
| K36–K50 | Smoothing welds, chamfering edges, preparing concrete or metal. |
| K60-K100 | Intermediate sanding and preparation for painting, coating, or finer finishing. |
The 115 mm diameter is the more convenient choice for edges, smaller surfaces, pipes, corners, and hard-to-reach areas. For larger surfaces and higher material removal rates, the 180 mm diameter corundum fiber grinding disc is the better option.
No. Fiber grinding discs are designed for surface finishing, rust removal, smoothing, and material removal. They are not intended for cutting.
