3M 7010328268 Abrasive Disc 320 Grit 12 Inch Wet or Dry

Product Description

The 3M 7010328268 is a coated abrasive disc from the Wetordry 431Q series, designed for precision finishing in both wet and dry sanding applications. Built on a C-weight waterproof paper backing, it carries silicon carbide mineral at 320 grit for fast material removal and a smooth surface finish. At 12 inches in diameter, this disc suits random orbital sanders and hand-sanding blocks used by auto body technicians, marine finish specialists, woodworkers, and metal fabricators. The adhesive backing allows quick attachment with no additional fasteners required.

This disc is suited for finish sanding on paint, primer, gel coat, metal, and wood surfaces in both professional shop and field environments. Running it wet reduces loading and extends the useful life of the disc, while dry use is equally supported by the durable paper construction. It is a practical choice for surface prep before topcoat application in automotive and marine refinishing workflows.

Key Features

• Silicon carbide mineral cuts faster than aluminum oxide and leaves a finer surface finish
• C-weight waterproof paper backing supports wet sanding to reduce loading and extend disc life
• 320 grit rating suited for fine finishing and pre-topcoat surface preparation
• 12-inch diameter with adhesive backing for direct attachment to compatible random orbital sanders
• Versatile for use on paint, primer, gel coat, metal, and wood substrates

Compatibility

Designed for use with random orbital sanders and hand-sanding applications that accept 12-inch adhesive-backed abrasive discs. Suitable for wet or dry use across automotive, marine, wood, and metal finishing applications.

Installation Notes

Attachment and removal of abrasive discs should be done with the sander powered off and disconnected from any power source. Ensure the sander backing pad is clean and free of debris before applying the disc to achieve full adhesive contact. When sanding wet, control water runoff to avoid contact with electrical components on powered equipment. Dispose of used abrasive discs in accordance with local regulations, especially when sanding lead-based coatings or hazardous materials.
