Ultra-fine hand-sanding pad

This 3M 7448BULK pad uses silicon carbide abrasive in a non-woven construction rated at grit 2000 and 2500. The open-coat design resists loading and heat build-up during use. Gray colour coding identifies the ultra-fine grade for final surface preparation.

Buyers needing aggressive material removal

The ultra-fine grit range is not suited to heavy stock removal or coarse levelling tasks. Users who require a more aggressive cutting action should consider a lower-graded abrasive. Buyers needing a specific backing type or dimensions not listed here should verify compatibility before purchase.

Questions about this item

When will the silicon-carbide grit on the 7448 pad wear down enough to need replacing?

The ultra-fine 2000-2500 grit surface gradually dulls as silicon-carbide particles fracture; replace the pad once it no longer cuts cleanly or leaves an inconsistent finish.

What limits how long I can sand continuously with the 7448 hand pad before it stops cutting effectively?

Heat buildup and loading of the open-coat non-woven structure are the first limits; the pad resists heat but accumulated swarf reduces abrasive contact and cut rate.
