    Lapping Film for Aluminum and Soft Metals

    This film quickly smooths out soft metal without clogging thanks to its silicon carbide abrasive. And since the abrasive is embedded in the film, there’s no mess like with lapping paste and slurries. Film is waterproof. Grit and microns are approximate.

    Sanding Sheets for Stainless Steel and Hard Metals

    Image of Product. Front orientation. Sandpaper. Sanding Sheets for Stainless Steel and Hard Metals.
    The abrasive on these sheets is hard enough to cut tough metals. They hold up when wet sanding or exposed to grease, chemicals, cutting fluids, and other solvents.
    Cloth Abrasive Backing—Flexible and tear resistant, it's good for contoured or rounded surfaces where a rigid backing could crack or rip.
    Aluminum Oxide Abrasive—The most versatile and affordable abrasive we offer is a good choice for most sanding jobs.
    Silicon Carbide Abrasive—Super sharp to cut quickly under light pressure. Silicon carbide is hard but brittle, so it tends to wear out sooner than other abrasives.
    Grit—The lower the grit number, the rougher the finish and the duller the appearance. The higher the grit number, the more polished the finish and the more satin or mirrored the appearance.
