Aluminium oxide sandpaper assortment

This pack contains 25 sheets of 9 by 11 inch aluminium oxide sandpaper in a single box. The range covers grits from 60 to 220 so users can move from heavy stock removal through to fine finishing without changing brands. It suits woodworkers, metalworkers and DIYers who want one purchase to handle several preparation stages. Buyers who need waterproof wet-and-dry paper or specialised ceramic abrasives will not find them here.

Dry hand-sanding thermals and dust

The sheets are designed for dry hand sanding or use with a hand block so no power draw or fan noise is involved. Heat builds only from friction at the work surface and stays low during normal intermittent use. The resin bond holds the grit firmly which reduces premature shedding and keeps the cutting action consistent. The product is not suited to high-speed machine sanding where heat and loading would increase quickly.

Resin bond and standard sheet size

A resin coating replaces ordinary glue bonds to extend abrasive life across wood metal plastic and painted surfaces. Each 9 by 11 inch sheet tears cleanly to fit common sanding blocks or can be used full size for larger panels. The box packs 25 sheets flat to prevent curl and makes it easy to pull a single grit without disturbing the rest. No hook-and-loop backing is provided so the sheets cannot be used on random-orbit pads.

Questions about this item

How do I attach the 9" x 11" sheets to my orbital sander, and what step causes premature tearing?

Cut or fold the sheet to match the sander's pad size, then clamp it under the tension brackets; the step users skip is aligning the grain direction with the pad's motion, which makes the resin bond fail early.

When will the aluminum oxide grit on the 220C sheets need replacement during a refinishing job?

Replace a sheet once the cutting feel drops noticeably — typically after several square metres of wood or between coats of polyurethane — because the resin bond holds the grain until it dulls, not until the backing wears through.

What limits continuous sanding with the 220C grit before the sheet stops cutting effectively?

Heat buildup in the resin bond is the first limit; prolonged pressure on hard woods or metal softens the adhesive, causing the aluminum oxide grains to shed and the sheet to glaze over.
