Hole Alignment and Extraction Performance
Dust extraction on a dual-action sander depends heavily on how well the disc holes align with the backing plate ports. 6 inch DA sandpaper features a 150mm diameter and is available in 6-hole, 8-hole, or multi-hole layouts to match various sander brands. When ports are correctly aligned, dust passes through the abrasive face instead of clogging the surface. This clarity is crucial during body filler and primer sanding, where heavy dust loads can obscure the work surface. The abrasive material options include aluminum oxide or silicon carbide, running from P80 to P2000.
Backing and Sizing Limitations
Hook and loop or PSA backing options are offered, allowing quick swaps on standard DA tools. However, size compatibility is strict; a 150mm disc requires a 6-inch backing plate. Running a 150mm disc on a 5-inch plate causes the edge to overhang, which leads to uneven wear and lifted edges during rotation.
Body Shop Application
In collision repair, the discs step from P80–P120 for leveling filler, to P180–P240 for blending, and P320–P400 before primer. They also serve furniture manufacturing for broad flat panels, metal shops for pre-brush surface preparation, and wood coating operations between layers.
Factory Matching and Shipment
To avoid misfits, buyers can provide a backing plate sample, and Dongguan Sansha Abrasives Co., Ltd. will match the exact hole positions, diameter, and backing format. Bulk orders follow this approved sample standard. Small batch dispatches typically take three days, while larger volumes require about a week. The transaction requires a 50% deposit, with the balance due after inspection.
