3M Company 1/4SHT5PK320 Quarter Sheet Sandpaper 320 Grit

Product Description

The 3M COMPANY 1/4SHT5PK320 is a quarter-sheet abrasive sandpaper designed for use with power sanders in finish sanding applications. Each pack contains 5 sheets of 320-grit abrasive, suited for ultra-fine material removal, surface prep between coats, and final smoothing on wood, metal, or painted surfaces. At 1.46 pounds per pack, the sheets are built for durability under repeated power-sanding cycles. Licensed trades and skilled finishers reach for this grit range when surface finish quality is the primary concern rather than stock removal rate.

This sandpaper is intended for use with standard quarter-sheet finishing sanders in residential and light commercial settings. Typical applications include final wood surface prep before staining or topcoating, scuff-sanding between paint or primer coats, and light deburring of metal surfaces. The 320-grit rating positions this product at the fine end of the abrasive spectrum, making it appropriate for finishing stages rather than aggressive material removal. It is sold in a 5-pack configuration and is available in cases of 20 packs.

Installation Notes

Secure the sheet firmly to the sander's clamping mechanism or hook-and-loop pad before operation to prevent slipping. Inspect the sheet for wear or loading and replace when cutting efficiency drops. Always disconnect or power down the sander before changing abrasive sheets. Follow applicable workplace safety guidelines for dust collection when sanding finishes that may contain hazardous materials.
