3M 7000118908 Psa Cloth Sanding Disc 8 Inch 36 Grit

Product Description

The 3M 7000118908 is a pressure-sensitive adhesive (PSA) cloth sanding disc designed for heavy-duty material removal in professional finishing and fabrication applications. Built on an X-weight cloth backing, this disc handles aggressive grinding and sanding without tearing or edge breakdown. The aluminum oxide abrasive grain cuts fast, runs cool with resin bond protection, and delivers consistent stock removal across a wide range of surfaces. The PSA backing bonds securely to a backup pad or steel platen and releases cleanly for fast disc changes during high-volume work.

This disc is suited for metalworking, woodworking, and composite surface preparation in industrial and trade shop environments. At 8 inches in diameter with a 36-grit cut, it handles aggressive stock removal, weld blending, and surface leveling. It is compatible with both wet and dry sanding applications, making it adaptable to different shop setups and material types. Sold in a box with a minimum quantity of 5 discs.

Key Features

• Pressure-sensitive adhesive backing adheres firmly to backup pads or steel platens and releases cleanly for fast replacement
• X-weight cloth backing resists tearing and edge wear during aggressive sanding passes
• Aluminum oxide abrasive delivers fast cutting action with long service life across multiple surface types
• Resin bond shields the abrasive layer from heat damage, extending disc life in continuous-use applications
• Compatible with both wet and dry sanding applications

Compatibility

Designed for use with standard PSA backup pads and steel platens that accept 8-inch diameter adhesive-backed sanding discs.

Installation Notes

Installation is performed by pressing the PSA backing firmly onto a clean, dry backup pad or steel platen, ensuring full surface contact to prevent disc slippage during operation. Inspect the backup pad or platen for debris or adhesive residue before mounting a new disc. Remove and replace the disc when cutting action diminishes or when backing shows signs of wear. Follow machine manufacturer guidelines for maximum RPM ratings when selecting a compatible sanding tool.
