3M 7010327516 Sanding Disc 3 Inch P400 Grit Ao

Product Description

The 3M 7010327516 is a 3-inch coated abrasive sanding disc designed for high-production and general-purpose material removal across a wide range of surfaces. Built on a C-weight paper backing with premium aluminum oxide mineral, this disc delivers fast cut and consistent performance through extended use cycles. The open-coat construction and load-resistant coating help prevent premature disc loading, extending abrasive life in demanding shop environments. The Hookita attachment system allows fast disc changes and disc reuse without adhesive residue or alignment issues. Licensed tradespeople and production finishing operators rely on this disc for reliable, repeatable results.

This disc is well suited for sanding paint, primer, wood, metal, plastic, and composite materials including fiberglass. The P400 grit rating targets fine finishing and surface prep work where scratch pattern control matters. Applications include high-production sanding lines and general industrial or fabrication environments where both speed and surface quality are required. The 3-inch diameter fits standard random orbital and disc sanders equipped with a compatible Hookita-style interface.

Installation Notes

Disc installation and replacement should be performed with the sander powered off and disconnected from its air supply or power source.
