3M 7000120220 Aluminum Oxide Sheet 80 Grit 9x11 in

Product Description

The 3M 7000120220 is an aluminum oxide abrasive sheet designed for sanding and surface preparation tasks in trade and light industrial environments. Built on a D-weight paper backing, the open-coat construction reduces loading and keeps the abrasive cutting efficiently across wood, metal, and composite surfaces. At 80 grit, this sheet sits in the medium abrasive range, making it well suited for stock removal, leveling, and preparation work before finish coats. Each sheet measures 9 inches x 11 inches, a standard hand-sheet size compatible with most block and pole sanders.

This sheet is used in residential and commercial finishing applications where hand sanding or backing-block work is required. Typical scenarios include cabinet and millwork shops, drywall preparation, metal deburring, and general surface conditioning ahead of primer or topcoat. The open-coat aluminum oxide mineral limits clogging on resinous or soft materials, extending usable sheet life compared to closed-coat alternatives.

Key Features

• Aluminum oxide mineral provides consistent cut and durability across wood, metal, and composite surfaces
• Open-coat construction reduces loading and extends sheet life on resinous or soft materials
• D-weight paper backing offers flexible support for contour and flat surface sanding
• 80 grit for medium-duty stock removal and surface leveling
• Standard 9 inches x 11 inches sheet size fits most hand blocks and pole-sanding frames

Compatibility

Designed as a standard 9 inches x 11 inches hand sheet for use with compatible sanding blocks and manual sanding applications across woodworking, metal finishing, and surface preparation trades.

Installation Notes

No power shutdown or mechanical lockout is required for hand-sheet abrasive use. Secure the sheet firmly to a sanding block or backing pad before use to maintain even pressure and prevent tearing. Inspect the sheet regularly during use and replace when mineral breakdown or loading reduces cut rate. Dispose of used abrasive sheets per local regulations when loaded with hazardous materials such as lead paint dust.
