The Gangying GY98 Vulcanized Fiber Disc is the heavy-duty disc in this group: a 100 mm disc with a 16 mm bore, premium brown aluminum oxide and a 0.8 mm vulcanized fiber backing. It is rated to 80 m/s and is positioned for angle-grinder stock removal.
The grit range is P24-P120, so this is a coarse-to-medium abrasive for weld seam and burr grinding, paint and rust removal, and hard industrial surface preparation. It also appears in bamboo and wood product applications at the finer end of the range.
Built for angle-grinder pressure
Fiber discs are different from paper sanding discs. The 0.8 mm vulcanized fiber backing gives the abrasive face enough stiffness to take pressure during grinding and stock removal. The product data specifically names angle-grinder work, and the 80 m/s max speed should stay visible in buyer discussions.
The 100 mm diameter and 16 mm bore are fixed specifications in this listing. Those dimensions matter because the buyer must match the disc to the machine and backing setup already in use.
Grit range from P24-P120
The P24-P120 range is much coarser than a finishing sheet:
- P24-P36 - aggressive removal, weld seam work and heavy burr grinding.
- P40-P60 - paint and rust removal where the surface still needs strong cut.
- P80-P120 - medium cleanup and preparation, including finer work on bamboo and wood products.
Because the whole range sits in a removal-focused band, it should not be described as a fine polishing paper. It is a fiber disc for grinding, blending and preparation.
Abrasive and backing
The abrasive is premium brown aluminum oxide. The existing product note emphasizes uniform grain that does not shed, which supports consistent cut on weld seams, burrs, paint and rust. The backing is 0.8 mm vulcanized fiber, giving the disc its working body and stiffness.
Together, those two specifications define the product more clearly than broad claims. Buyers comparing fiber discs will usually ask for diameter, bore, backing thickness, grit and speed rating; all of those are available here.
Application areas
- Weld seam and burr grinding - coarse grits remove raised metal and sharp edges.
- Paint and rust removal - medium grits clean surfaces before further preparation.
- Shipbuilding, automotive and bridge work - the product data names these as target industrial uses.
- Bamboo and wood products - finer grits can be used where the application calls for controlled removal.
