3M 7000118871 Psa Cloth Sanding Disc 50 Grit 2 Inch

Product Description

The 3M 7000118871 is a PSA cloth sanding disc designed for heavy-duty material removal in industrial and trade environments. The disc uses a pressure-sensitive adhesive backing that mounts securely to a backup pad or steel platen and releases cleanly when replacement is needed. Built on an X-weight cloth backing, it resists tearing and edge wear during aggressive grinding and finishing passes. The aluminum oxide abrasive cuts fast and maintains a long service life across a wide range of workpiece materials. A resin bond protects the abrasive layer from heat buildup, extending disc life in sustained use.

This disc is suited for metalworking, fabrication, and surface preparation applications where a 2-inch PSA disc format is required. At 50 grit, it handles aggressive stock removal and weld blending on ferrous and non-ferrous metals as well as wood and composites. The disc is rated for use in both wet and dry conditions, making it versatile across shop and field settings. Machinists, fabricators, and finishing technicians commonly use this disc on right-angle grinders and disc sanders fitted with compatible backup pads or steel platens.

Key Features

• Pressure-sensitive adhesive backing adheres firmly to backup pads or steel platens and allows fast, clean disc swaps
• X-weight cloth backing withstands aggressive applications without tearing or edge breakdown
• Aluminum oxide abrasive delivers fast cut rate and extended service life on a broad range of surfaces
• Resin bond dissipates heat to protect abrasive integrity during prolonged use
• Rated for wet and dry use, adding flexibility across application environments
• 15000 RPM maximum speed rating supports high-speed tool compatibility

Compatibility

Designed for use with backup pads or steel platens that accept 2-inch PSA-style sanding discs on right-angle grinders and disc sanders.

Installation Notes

Installation is performed by trade professionals such as machinists, metal fabricators, and finishing technicians. Before mounting or removing the disc, power down the tool and confirm the spindle has come to a complete stop. Peel the release liner and align the disc squarely onto a clean, dry backup pad or steel platen to ensure full adhesive contact. Do not exceed the rated maximum speed of 15000 RPM; confirm tool RPM against disc rating before use.
