3M 7000119282 Hookit Abrasive Sheet 320 Grit 3x4 Inches

Product Description

The 3M 7000119282 is an aluminum oxide Hookit abrasive sheet designed for sanding and surface preparation tasks in automotive, woodworking, and general finishing applications. Built on a C-weight paper backing, it offers a balance of flexibility and durability suited to flat and contoured surfaces. The open-coat construction delivers an aggressive cut rate while a load-resistant coating helps extend abrasive life by reducing clogging. At 320 grit, this sheet is well suited to fine finishing passes and between-coat sanding. Each sheet measures 3 inches x 4 inches and is sold individually.

This sheet is used in light to medium material removal and finish-sanding scenarios across automotive body work, wood finishing, and general-trade surface prep. The Hookit attachment system allows quick, tool-free sheet changes on compatible 3M Hookit backup pads and sanders, reducing downtime during multi-stage sanding operations. It performs reliably on painted surfaces, wood, primers, and similar substrates where controlled cut and finish quality are both required.

Installation Notes

Attach the sheet to a compatible Hookit backup pad by pressing the sheet face firmly onto the pad until fully seated. Ensure the sanding surface is clean and free of debris before beginning to avoid premature loading. Inspect the sheet periodically during use and replace when cut rate drops or loading is visible. Follow applicable workplace safety guidelines for dust control when sanding painted or coated surfaces.
