3M Company DISC5IN5PK320 Sanding Disc 320 Grit 5 Inch

Product Description

The 3M COMPANY DISC5IN5PK320 is a 5-pack of 5-inch power sanding discs engineered for use with random orbital and disc sanders. These ultra-durable abrasive discs feature a universal hole pattern and a 320-grit abrasive surface suited for fine finishing work. At 320 grit, these discs remove light surface imperfections, smooth between coats, and prepare surfaces for final finishing. Each pack contains 5 discs. Licensed trades professionals and experienced DIYers working on wood, composite, or painted surfaces will find these discs appropriate for finish-stage surface preparation.

These sanding discs are designed for power sanders in light finishing and surface prep applications. The 5-inch diameter and universal hole configuration make them compatible with a wide range of orbital and random orbital sanders used in woodworking, cabinetry, trim carpentry, and general surface finishing. The 320-grit rating positions them as a fine-stage abrasive, typically used after coarser grits have removed stock material and the surface requires smoothing before sealing or topcoating.

Key Features

• 320-grit abrasive surface for fine finishing and between-coat sanding
• 5-inch diameter with universal hole pattern for broad sander compatibility
• Ultra-durable construction for extended disc life under power sanding conditions
• Sold as a 5-pack, with 20 packs available per case
• Suitable for wood, painted surfaces, and composites at the finish stage

Compatibility

Designed as an OEM-style replacement disc for 5-inch random orbital and disc power sanders using the universal hole pattern configuration.

Installation Notes

These discs are installed by hand onto compatible 5-inch sanding pad backing plates. Ensure the sander is powered off and unplugged before changing discs. Verify the disc is seated securely on the backing plate before operating the tool. Follow applicable safety guidelines for personal protective equipment, including eye and respiratory protection, when sanding.
