3M 7000118899 Psa Cloth Disc 30 Inch 36 Grit Ao

Product Description

The 3M 7000118899 is a heavy-duty PSA cloth sanding disc designed for aggressive material removal on a wide range of surfaces. The pressure-sensitive adhesive backing bonds firmly to backup pads or steel platens, enabling fast disc swaps with clean removal and no adhesive residue left behind. The disc uses aluminum oxide abrasive for fast cutting action and extended service life. A resin bond system protects the abrasive layer from heat buildup, keeping the disc cutting efficiently through long runs. At 30 inches in diameter and 36 grit, this disc is built for high-stock-removal operations where durability and consistency matter.

This disc is suited for heavy grinding and sanding applications in industrial, fabrication, and finishing environments. The X-weight cloth backing resists tearing and edge wear under aggressive pressure, making it appropriate for wide-belt-style or large-platen machine operations. It supports both wet and dry sanding, giving shops flexibility across different process requirements. Operators working on metal, wood, composites, or similar hard surfaces will find the 36-grit cut rate practical for initial stock removal and surface preparation steps.

Installation Notes

Ensure the backup pad or steel platen surface is clean and free of adhesive residue before applying the disc. Power down and lock out the machine before changing discs. Press the disc firmly across the full face of the platen to eliminate air pockets and ensure full adhesive contact. Follow equipment manufacturer guidelines and applicable facility safety procedures when operating large-diameter abrasive disc machinery.
