5-inch 120-grit sanding disc for power tools
This Ali Industries disc uses an aluminium-oxide abrasive bonded with red resin to tackle wood, metal, drywall, fibreglass and painted surfaces. The 120-grit rating makes it suited to intermediate smoothing and prep work rather than heavy stock removal or final finishing. It is sold as a single consumable for handheld or benchtop sanders.
Hook-and-loop attachment for quick changes
The backing uses a hook-and-loop fastening system that mates with compatible sander pads, letting you swap discs in seconds without tools or adhesive residue. This design keeps the work surface free of glue build-up and reduces downtime between grit changes. The disc simply presses onto the pad and stays secure under vibration.
Resin bond resists heat and humidity
The resin bonding agent is formulated to withstand the heat generated during extended sanding and to resist moisture absorption in humid conditions. This helps the abrasive grains stay anchored longer, giving more usable life per disc. No additional accessories or software are included with this item.

Questions about this item
How long does the resin bond hold up on the 120 grit disc during extended sanding?
The resin bond resists heat and humidity, giving the aluminium-oxide disc longer life under sustained use.
Does the 5-inch hook-and-loop disc run hot or create extra vibration on a random-orbit sander all day?
The resin-bonded construction reduces heat build-up, keeping the disc cooler and cutting vibration during long sessions.
What sander pad do I need to attach the 3723 disc?
A 5-inch hook-and-loop backing pad on your orbital or random-orbit sander accepts the disc directly.
