Gangying Vulcanized Fiber Disc

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 provides stiffness for grinding and stock removal with an angle grinder. Match the 100 mm diameter, 16 mm bore and 80 m/s maximum speed to the machine and backing pad before use.

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.

The coarse-to-medium range is intended for grinding, blending and surface preparation rather than fine polishing.

Abrasive and backing

The abrasive is premium brown aluminum oxide for cutting weld seams, burrs, paint and rust. The 0.8 mm vulcanized fiber backing gives 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 - industrial grinding and surface preparation.
• Bamboo and wood products - finer grits can be used where the application calls for controlled removal.

Packaging and inquiry

GY98 fiber discs are packed 100 discs per box. The reference price shown above is for the listed 4 in / 100 mm format. Send an inquiry with grit mix, box quantity and intended machine use so the quotation can be matched to the 100 mm, 16 mm bore specification.
