3M 7000045069 Psa Cloth Sanding Disc 3 Inch P240

Product Description

The 3M 7000045069 is a PSA cloth sanding disc designed for heavy-duty material removal in professional grinding and finishing applications. The pressure-sensitive adhesive backing bonds securely to a backup pad or steel platen for fast, stable positioning and releases cleanly when it is time for replacement. The disc uses aluminum oxide abrasive, which cuts aggressively and delivers long service life across a broad range of workpiece materials. A resin bond system protects the abrasive layer from heat buildup, helping maintain cutting performance through extended use. At a 3 inch diameter and P240 grit rating, this disc suits fine finishing passes in metalworking and woodworking shops.

This disc is suited for both wet and dry sanding applications on metal, wood, composites, and similar surfaces. The X-weight cloth backing resists tearing and edge wear under aggressive operating conditions, making it appropriate for production environments where discs see repeated, high-load use. It is commonly used with pneumatic or electric angle grinders and random orbital tools fitted with a compatible backup pad or steel platen. Typical users include machinists, fabricators, and industrial finishing technicians working in manufacturing or maintenance settings.

Compatibility

Designed for use with backup pads and steel platens that accept 3 inch PSA cloth discs. Verify platen or pad diameter and PSA compatibility before installation.

Installation Notes

Power down and disconnect the tool from its air or electrical supply before mounting or removing any abrasive disc. Clean the backup pad or platen surface of dust and debris to ensure full adhesive contact before pressing the disc into place. Inspect the disc for damage before each use and do not exceed the rated maximum speed of 10000 RPM. Installation and use of abrasive products in industrial settings should follow applicable ANSI B7 safety standards and the tool manufacturer guidelines.
