3M 7000119551 Psa Abrasive Disc 80 Grit 6 Inch 100 Pack

Product Description

The 3M 7000119551 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface preparation, stock removal, and finishing work on a wide range of materials. This disc measures 6 inches in diameter and features 80-grit aluminum oxide abrasive, placing it in the medium grade cutting range. The C-weight paper backing provides a balance of flexibility and support, allowing the disc to conform to slightly contoured surfaces while maintaining consistent cut rate. Each disc uses a PSA mount system for fast, tool-free attachment to compatible backup pads. Sold in a 100-disc package, this part is used by metalworkers, woodworkers, and trade professionals who require a reliable supply for production or service environments.

These discs are engineered for use with random orbital sanders in both shop and field applications. Typical uses include paint and rust removal, wood sanding, weld blending, and surface conditioning on flat or mildly contoured workpieces. The aluminum oxide abrasive is suited for ferrous and non-ferrous metals as well as wood substrates. The 6-inch diameter is a standard size in HVAC fabrication shops, cabinet shops, and general trade service work where random orbital sanders are the primary tool. The Series 236U construction delivers consistent performance across the disc life.

Key Features

• 80-grit aluminum oxide abrasive for medium-grade stock removal and surface preparation
• 6-inch diameter fits standard PSA backup pads for random orbital sanders
• C-weight paper backing balances flexibility and rigidity for flat and lightly contoured surfaces
• Pressure-sensitive adhesive mount allows fast disc changes without tools
• No vacuum holes — suited for applications where dust extraction through the disc is not required
• 100 discs per package supports production volume and reduces reorder frequency

Compatibility

Designed for use with random orbital sanders that accept 6-inch PSA (pressure-sensitive adhesive) backup pads. No vacuum hole pattern, so dust port compatibility through the disc face does not apply.

Installation Notes

Attachment is performed by peeling the liner from the PSA backing and pressing the disc firmly and evenly onto a clean, dry backup pad. Ensure the backup pad surface is free of debris or adhesive residue from prior discs before mounting, as contamination reduces adhesion and can cause disc separation during use. Operate the sander at the speed recommended by the sander manufacturer for 6-inch discs. Discard any disc showing tears, edge lifting, or uneven wear to avoid workpiece damage or injury.
