This 4-inch flap disc features aluminum oxide abrasive grains bonded to a woven fiberglass backing plate, specifically engineered for grinding and weld cleanup on steel, stainless steel, and aluminum. The disc measures 100 mm in diameter and 16 mm in thickness, optimized for handheld angle grinders used in fabrication and maintenance workshops. The fiberglass backing is treated to resist heat and mechanical stress during continuous operation.
The abrasive grain is applied using a resin-based bonding system, which ensures even grain exposure and consistent cutting over the disc’s lifespan. Unlike lower-grade discs with loose or uneven flaps, this product uses a tightly woven backing with precisely cut flaps to reduce vibration and improve control. These discs are not designed for heavy stock removal but excel in light deburring and surface blending.
Primary buyers include metal fabricators, welding repair shops, and industrial maintenance teams in Southeast Asia and export markets. Packaging is bulk carton, typically 25 to 50 discs per box. Trade terms are FOB Medan, with lead times of 10 to 14 days. Buyers should confirm backing plate density and flap count per disc, as these directly impact performance and tool life.

Before ordering, confirm the exact flap count, backing density, and grit size of the batch. Request physical samples to test on your target materials and measure disc thickness variation with a micrometer. Ensure the backing is fully resin-coated and shows no signs of fraying or delamination. Do not rely on supplier claims without independent verification.
Trade terms are FOB Medan. Lead time is typically 10 to 14 days after payment. Payment is usually 50% advance, 50% against BL copy. Confirm Incoterms 2020 usage and whether packaging is palletized or loose. Request a copy of the export documentation format, including commercial invoice and packing list, to ensure compliance with your country’s import regulations.
Quality inspections should include checking for flap alignment, absence of grain shedding, and consistent backing thickness. Use a surface roughness tester on ground samples to verify finish quality. Retain samples from each shipment for comparison. Request a certificate of origin and material safety data sheet (MSDS) for aluminum oxide to meet customs and safety compliance requirements.
