They are compatible with any 150mm orbital sander that uses a standard hook-and-loop (Velcro-style) fastening system.
P320 is a fine-to-medium grit designed for smoothing and preparation. For heavy paint removal, you would need a much coarser grit, such as P60 or P80.
This package contains 50 individual 150mm sanding discs.
The 7944 SiaOne series is primarily designed for dry sanding. Using them for wet applications may degrade the adhesive backing.
P320 refers to the FEPA grit standard, indicating that the abrasive particles are sized to produce a smooth, refined surface finish appropriate for fine sanding.
Check the hook-and-loop pad on the sander for worn-out hooks. Clean the pad with a stiff brush to remove embedded dust.
Reduce downward pressure and ensure the sander's dust extraction system is operating correctly. If sanding gummy wood or soft materials, clear the surface debris more frequently.
Ensure the sander is kept flat against the surface. Tipping the sander can cause the edge of the disc to dig in.
To set up these discs, ensure your orbital sander's backing pad is clean and free of dust. Simply align the disc holes with the vacuum extraction holes on your sander's pad and press firmly to engage the hook-and-loop fasteners.
Compatibility: These discs are designed for any 150mm random orbital sander utilizing a standard hook-and-loop pad system.
