These specific discs do not have pre-cut holes. If your sander requires hole alignment for dust extraction, you may need to use a punch tool or opt for a different disc model.
These discs are primarily designed for dry sanding. Using them for wet sanding may reduce their lifespan significantly.
P120 is a coarse grit used for aggressive material removal, leveling body filler, and smoothing rough surfaces.
Each pack contains 20 individual 77mm sanding discs.
Yes, they are highly effective for removing thick paint or varnish from wood surfaces, though they are quite coarse for final finishing.
Ensure the backing pad is free of dust and debris; check that the hook-and-loop interface is not worn out.
Reduce pressure on the sander and clear the surface of heavy paint or filler dust periodically.
Ensure you are keeping the sander flat; do not tilt the edge of the tool into the workpiece.
To set up these discs, align the center of the disc with your sander's 77mm backing pad and press firmly to engage the Hook'N'Loop material. Ensure the pad is clean of debris before attachment to prevent the disc from slipping. These discs are compatible with any 77mm orbital or rotary sander equipped with a hook-and-loop backing plate. For care, store discs in a cool, dry environment away from high humidity to prevent the backing material from degrading or the grit from shedding. If using for wet sanding, ensure your equipment is specifically rated for wet-dry applications, although these discs are optimized for dry use.
